Although image shows effects of sag on a rear axle under a heavy load, similar improvements will be made when the Timbren SES is installed on a front end.

The resistance from Timbren's Suspension Enhancement System works with the Mercury Mountaineer's factory suspension to keep the Mercury Mountaineer level, thereby improving your driving performance. When a truck bed is loaded, the rear of the Mercury Mountaineer will sag under the load, and the front will sag under the burden of heavy equipment such as a snow plow. In this case, the axle is handling not only the weight of the load, but more of the Mercury Mountaineer's weight as well. Because less weight is on the opposite axle, those tires are making significantly less contact with the road meaning there is less traction and therefore a decrease in overall control, handling and stopping.


Install diagrams of Timbren hollow rubber springs

The Timbren system has a Mercury Mountaineer-specific bracket that will be bolted onto each frame rail above the front axle. Hollow rubber springs are bolted to the bottom of the bracket, hanging down so that the bottom of the spring is touches the axle. Because the spring is already making contact, it is working at once to cushion and support the Mercury Mountaineer's existing suspension.


Animation of a standard Timbren rubber spring

Timbren Suspension Enhancement Systems are designed to work progressively. When the hollow rubber springs are compressed, the convoluted design causes them to quickly collapse along the folds. Once the folds are compacted, the stacked barrel shape provides increased resistance, stiffening the suspension and keeping the Mercury Mountaineer level.

Timbren suspension system works to prevent body roll

Each hollow rubber spring works independently to support the driver's or passenger's side of the Mercury Mountaineer. This is helpful when you swerve or make sharp turns. Each spring is activated when it is needed, so body roll is greatly reduced. The independent action also works well when hauling off-center loads.

A snowplow mounted to the front of the truck will require extra suspension support for the front axle.

Timbren's Suspension Enhancement System will raise the front of the end of the Mercury Mountaineer when heavy equipment, such as a plow, is attached. Headlight beams will be pointed in the right direction and tire wear will be reduced. If the plow is off center or has an extension, the hollow rubber springs will automatically compensate for this as well.


An empty truck on a bumpy road without Timbren

Another great feature of the rubber construction is that the springs absorb most of the road shock, creating a smoother, more stable ride overall. Wear and tear on the factory suspension is also lessened as the rubber springs work to prevent bottoming out on rough roads.


Compared to the competition:


Timbren's suspension enhancement systems are much easier to install than air springs - no air hoses are needed to be run, no compressors or gauges to hook up, and no manual adjustments necessary. The rubber construction causes Timbren's springs to be more elastic than similar products constructed of micro-cellular urethane. More elasticity allows for a more comfortable ride because the rubber has more travel.

Video Transcript for Timbren Front or Rear Suspension System Installation - 2001 Ford Explorer

Today on our 2001 Ford Explorer well be installing the Timbering Suspension Enhancement System part number TGMFK10. First, well need to go ahead and raise the vehicle and remove the manufacturer bump stop. To do this well remove the nut off the top of the bump stop stud. First, well go ahead and spray down the fastener with some spray lubricant. This will assist us in removing it because over time its gonna build up rust, dust, dirt, and debris. Quick tech tip, it may be necessary to go ahead and put a block of wood in between the axel and the bump stop so that it holds it in position.

Youll notice theres a small nipple in the top of the bump stop that goes into the frame to stop it from spinning. Now well go ahead and put our block of wood in place and were ready to go ahead and start removing the fastener. Now, with the fastener removed well go ahead and remove the block of wood and our bump stop and here you can see the nipple that protrudes into the frame. Were ready to install the new Ion rubber spring. Before we put it in place lets go ahead and assemble it.

As the spring is already assembled well need to assemble the hardware and top plate. Weve got the new bolt thats provided with our install kit. Well go through the center of the ion spring, through the ion spring washer, and up through the top of the ion spring. After the bolt passes through the spring, well install the top plate provided with our install kit. Now were ready to go ahead and install it into the frame.

Once in the frame well install a flat washer and lock nut to secure it. Next, we can go ahead and tighten it down. Now with everything tightened down well go ahead and repeat the same process on the drivers side. And with both ion springs installed that will complete the installation of our Timbren Suspension Enhancement System part number TGMFK10 on our 2001 Ford Explorer.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I have attached the Timbren product to my 2012 Dodge Ram and am very impressed with the product. etrailer answered my question that I needed to know if the Timbren product would take the squat out of my truck when I hook up my 5th wheel rv. The proof is in the attached pictures I took to share with you and potential customers. Your customer service & product knowledge is outstanding and that is why I am a faithful customer. As far as the installation of the product, I could not find an easier thing to do....It's harder to change a light bulb! Of course your installation video was very informative which made things a lot easier. 79715

Fantastic....The truck drives like a dream! If and when I hit any potholes or bumps, of course you still feel them, but the control is there with no fish tailing. As far as pulling my 5th wheel, it feels like everything is one unit and floats right along!

Very good illustration and explanation. I have a 5th wheel and am experiencing the squat problem. Question: Is the installation strictly a friction fit or do I have to install a bolt with nut?

For John T. They are a friction fit, installed mine in less than 15 min. Slight harder ride when unloaded, but they work perfectly for carrying the load of the trailer. Highly recommend.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I finally had a chance to try these out and they work great. Granted, I do have what they market an ultra-light travel trailer, but for my configuration of my 2007 Dodge Durango (4.7L), this trailer totals out about 75% of my towing capacity. That being said, this vehicle has an abnormally smooth ride for it's size. Because of this, the weight at the hitch creates a slight sag in the rear when weighted over 400 lbs. It also created some suspension characteristics I didn't like, like the slow bounce over undulations. I was advised my shocks were in perfect condition and utilizing stiffer shocks would not prevent the sag and would make the overall ride too tight for me. This was the reason for looking into this option. Installation was as simple as it gets (pull off the old and put on the new). The only tools (if you want to call it that) are possibly a couple of 2x4 blocks (of course you're going to need a jack to jack up your vehicle). 4 inches total was needed to properly seat them. It took a total of 30 minutes, but 20 minutes was me pulling out my jack and jack stands, finding blocks, and taking my sweet time. My Durango rode as level as expected after installation. Photos would not show anything noticeable without actually measuring it (about 450 lbs on the tongue with my particular trailer - see photos). I also didn't have to adjust my mirrors, which was inherent in the slight sag I had before. It took bumps well and the ride was not as bouncy as before, more firm and controlled. The ride without the trailer is noticeably firmer, and with little bumps you can tell they're making contact. Mostly noticeable over speed bumps where my Durango would normally float over them due to the long travel. My Durango inherently didn't ride like a truck or large SUV, more like a sedan. Now, it "sorta" rides more like a truck. Not a deal breaker, but if you like your truck to keep riding smooth, these might not be for you. Pros: Works as advertised. Easy installation. Keeps your vehicle level. Firmer more controlled ride. Removed annoying bounces. Great quality build. Cons: With the clearance from your axel to your bump stop now ~1.5 inches, bumps will be felt if making contact (-1 star for me, but if this is not an issue for your application, you should add the star back). Overall, I would highly recommend this product, even for a smaller SUV like my Dodge Durango. That being said, it won't have the same smooth ride with the long travel as before, but definitely worth it if you're towing with the same type of vehicle. 489147

The Timbren rear suspension enhancement system did help my 2003 Ford F-150 a lot, I am extremely satisfied with the product and the rest of other products I purchased before from www.etrailer.com . It was an easy set up that didn't take more the 20 mins. to install. I will definitely recommend it and will continue to shop from this place, customer service is a big +, I'm really happy with them. 243021

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


i recently added a power lift to my 2002 mazda mpv to carry my husbands new power chair. i needed these to prevent the sagging that occurred when just the class III hitch was installed. we loaded the chair on the lift once and i knew we could not leave the sagging that way. i did not want the maintenance of air shocks, air bags or air springs so i ordered these and am very happy i did. it keeps everything level with the full load on the rear and does not affect the ride when loaded or empty (with just the hitch). i would recommend these if you just put people in the back of any van. Installation was very simple. jacked up van with floor jack i have with tire 1" off ground. i am not sure if my stock bumpers fell off or were stolen in the past but they were not there. i took off the one bolt (14mm), assembled the timbren ses with supplied long bolt (17mm) and left stock bumper mount on top (same orientation), used a deep socket (17mm) stuffed with a paper towel and short 3/8" extension and started the bolt by hand. then placed the 3/8" ratchet on and tightened it up. NOTE: I visited the hardware store before I started, with the assembled timbrens in hand. I bought two 7/16" washers and two 7/16" split lock-washers because it looked like the bolts would bottom out on the un-threaded portion before fully tightening them up. Sure enough, on the passenger side i had to add a 7/16" lock-washer to get it to snug up. There was alot of slack/play after the threads bottomed out on the un-threaded part of the bolt shaft. On the drivers side it did not need a lock-washer added. it tightend up without any play. I will check them periodically to see if they are coming loose. if so, I will place the lock-washer and the other flat washer I bought on both bolts, then assemble the rest and tighten up again with thread locker on the threads. The install went so fast if I had to take them down to add anything it would only be a few minutes for both sides. Nice stiff, controlled cornering without the roll. wish I added these years ago to make my minivan with the heart of a sports car even sportier. Thanks e-trailer, Carol S 162579

I have a 2016 Ford F150 Regular Cab with 6.5 foot box and 5.0 engine, 6400 lb payload package, 9.75" ring gear with 3.73 gears with a locker. (Hard to find!) Ease of installation is easy, with even minor mechanical skills. I took my time and it was 40 minutes to install both sides. Took some measurement of the factory bump stop distances to the axle - 6.5 inch's approximately. (Would take a lot of weight to compress it that far!! Have hauled some rocks before, almost 1 ton and it was still 3 inchs from touching the axle!) After installing I took some measurement of the gap between the plates and the rubber that will come into contact with when the suspension compress's. Left side (Driver) was 1.25 inch. (Full gas tank.) Right side (Passenger) 1.50 inch. Have not driven it yet to see how the suspension will ride before these Timbren Rubbers will come into play. Purchased these to help when I haul a 700 Yamaha Grizzley ATV (750 lbs approx.) and tow a camp trailer with a 550 lb tongue wt. approx. Separately the truck would be level, but with both it was squatting it to much. I am hoping this helps in that situation & to help stabilize the ride. Gave a 3 for easy of installtion, but yet to be determined how well it will help when towing & or hauling ATV or both, and how the ride will be empty. 471198

Thanks for sending in your product review! I spoke with my Timbren representative, who tells me that its likely the full tank of gas is causing the 14 inch space differential between the driver/passenger Aeon spring and the axle. They do have spacers available that are as small as a half inch, but all that would do in your case is make the other side 1/4 inch closer to the axle. Any load thats capable of compressing the suspension so the springs contact the axle would cause both springs to contact at the same time, so that small differential wouldnt be anything to be concerned about. Let us know if youre interested in the spacer, Timbren will send you one if youre interested.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


The order and shipping process was flawless -- the Timbrens arrived exactly when E-trailer said they would. An hour after they got here, I had them completely installed. As of this date (7/30/13), the posted instructions (and the ones that came with the Timbrens) are not quite correct for a new Tacoma, as I verified with a Timbren tech. (These are Tacoma-specific issues -- they may not apply to other trucks.) Do not jack the truck up. I ran the back tires up onto blocks (to give myself more room underneath) and set the parking brake. I put a jack stand under the differential -- probably not needed. I crawled under and did one side at a time -- loosen the u-bolts, remove the old bump stop, stick in the new Timbren, and tighten. Not technically demanding at all. My crawler dolly was very helpful. Some tips: use a 9/16 socket with an extension to put the nut onto the bolt inside the Timbren rubber spring and then tighten the bolt with an Allen wrench. When loosening the Tacoma's u-bolts, use a 3/4 socket. Depending on the clearance between the leaf springs and the frame, you may need to remove one side of the u-bolt assembly to install the Timbren because the angle of the baseplate is greater than the angle of the OEM bump stop. I was told that the u-bolt nuts on a Tacoma should be re-tightened with a torque wrench to about 70 foot/pounds. I found it a little tiring to lay on my back and torque the nuts, but then again I am verging on elderly. A young person in decent shape should have no trouble. I don't know yet if the Timbrens will help my saggy rear end when I am towing a trailer, but others have said that this will be very helpful. This is my second major purchase from E-trailer -- I am impressed with their selection, service, and pricing. 92404

To say I'm very happy with this product is an understatement. First off, shipping was fast and the communication from George was top notch. Secondly, installation was as easy as it gets. Find a safe, flat area to jack your truck up by the frame (this creates space between the factory bump stops and the axle) then remove the factory bump stops. You may need a flat head screw driver for this to pry the old bumps stops out (easy)... insert the new Timbren Suspension System...a 6 inch long 2x4 would be helpful here....safely place the 2x4 atop the axle directly under the Timbren system, then slowly lower the vehicle. The weight of the vehicle will force the Timbren system up into the receiving end and this should complete the install. It took me longer to dig out my floor jack, cut a small piece of 2x4, then installing the Timbren system. Lastly, I immediately hooked up my camper a 24' (27' all in) Forest River and instantly saw my 2016 RAM leveled out. I have a 3 hr trip planned in the coming weeks and will offer some feedback on the ride with this new Timbren system in place. Pretty impressed thus far 426206

Just what the truck asked for... I’m a Farrier, I carry a full workshop in the bed of my truck 24/7. I drive a 2001 Toyota Tacoma 4x4. After a couple months I redid the entire front and rear suspension and added heavy duty rear leafs. After about a year of driving and also adding more tools the truck began to sag a little bit. Ofcourse, the first thing anyone suggested was “airbags” but they didn’t know the use of the truck or where the truck goes from day to day. Being a Farrier, I travel on everything from paved freeways to down and dirty “4lo” back roads. I needed a maintenance and care free system that would allow for over extension and hold the extra weight of my tools and sometimes even a trailer. I did a ton of research and even talked to the Technician Staff at each company. I ultimately decided to go with Timbren SES Kit. It’s easy to install, maintenance free, free floating, and has the best warranty in it’s category. Since I have a custom setup (Ubolt Flip Kit from AllProOffroad) I had to design and build some landing pads to allow for an “interference free” contact with my system. After the first day of working, I am COMPLETELY satisfied with its performance and how my truck feels and drives. As for ”Etrailer” I am very happy with all the information and excellent customer service. I received my parts 2 days before it’s orignal date which makes me super Happy! 570702

A heavy workload on a Ram 1500 will cause the truck to squat with just 1 inch of clearance in the wheel-well. The stock suspension is soft and it feels precarious when under load. I would not say that Ram dropped the ball on their suspension since many of their 1500 customers do not load the truck down to use it to its rated capacity and the soft ride appeals to a large segment of drivers who cannot find it in other trucks. However, it seems that the Timbren bump stops are what should be on the truck if you are not getting a 2500 or 3500 but need to tow and haul. The Timbren rear enhancement system immediately improves the handling on the Ram 1500 and stands up even when placing it under load. It is almost like buying a whole new truck. I cannot compliment this product enough and I am extremely pleased with how the truck handles both loaded and unloaded. It is not too stiff and it does not feel bumpy like other enhancements might. But it feels sturdy and the truck feels stronger almost right away. I could have gone with a different distributor for these parts but etrailer.com is more than just a distributor. You can find official etrailer.com videos on most of their products which will give you honest information on their products and explain how to install and use those products. If you have a question, you will get a reply from them with an expert on the subject. They are interested in finding you solutions first and the sales are just a byproduct from their expertise. I did not find these parts cheaper anywhere else, but I still would have gone with etrailer.com even if they cost a little more. I chose etrailer.com because I know I can trust them to get me the good stuff. 510713

Ordered these (6,000 lb Kit) to cure getting too nose high when towing after installing a Bilstein 5100 Level Kit on my 2016 F150 SuperCrew 4x4 (front struts set on max 2.10" setting sitting nearly perfectly level). Tow a 29' overall length travel trailer (~5,500 lbs) and for work we use a 20'x8' enclosed trailer (~9,000 lbs when loaded). Use a WD hitch, but still get the nose up when pulling both. Install was easy. Read through the instructions and watched a video before they came in. Crawled underneath and installed in about 30 minutes after I received them. Didn't remove the spare or the heat shield like the video I watched showed. A lift would have made it easier of course, but can be done in the driveway if you like doing stuff yourself. Used the included spacer and have about a 1" gap, which falls in the advised .5" to 1.5" range from the instructions. I haven't gotten to use them with the work trailer, but I have pulled the travel trailer and they do exactly as advertised, cures the sag, and nose doesn't go up at all. May be slight nose up with the work trailer, but I wouldn't believe it will be like before. Driving while hooked up feels smoother, too, with less body roll/lean in turns. So, overall satisfied with the purchase. The only reason this is getting 4 stars is that, like others have stated, the parts that were painted left a lot to be desired. Very sloppy with some areas that were already flaking off and one part had a spot that was completely missed by paint. The piece that goes underneath the axle to secure the contact plate is not even painted, it's just raw metal. So, I'm curious about what that will look like after one salty winter here in MO. I may find some time before the winter hits and take everything off and do some painting myself, but for $215 you'd kind of think that wouldn't be something to worry about doing with a brand new part. 543563

The Timbrens are great. I have not had the truck with a full load yet but I anticipate they will help bring the truck back to level. The install went well but we were not able to use the additional spacer even with the longer bolts. We were not able to put enough pressure on the bolt to get the nut started. I don’t believe I will need the spacers so it should be ok. The directions didn’t include the amount of torque that was needed so I sent e-trailer an email. They checked with Timbren and the torque is 1/4 turn after they are tight. Ive attached some pictures of the completed install. 566262

The package arrived in only a few days, sooner than I had expected. I was impressed with Etrailer, the vendor. Opening the brown shipping box however, I was somewhat set off by seeing the Timbren SES box taped up like it went through WW3. It looked like a box that someone had opened once before and someone made an attempt to reseal it with another yard of tape. Opening the SES box confirmed my suspicions that someone had indeed attempted to install these once before and returned them as the 1 paragraph's directions were covered with greasy fingerprints . The parts looked OK so rather than wait for a second pair I just installed them. I have to say that the Timbren supplied written directions left a lot to be desired. I consider myself an above average home mechanic and I had difficulty understanding how to dissassemble the Jeeps front suspension. At the price I paid for these devices, Timbren should at least have made a better effort to create clearer directions. There was no directions on how to get the old bumpers off their perches (they are pressed in . They will only come out using some heat and a lever) , nor how to get the old cups off their perchs (there is one bolts holding each one into the perch, but bolts were so rusty I had to torch them off. I doubt the average Joe would have the knwledge, tools and determination to ge the old ones off). Don't try to do this job without using spring compressors to get the springs out. You'll never do it ! I had to google Timbren installation instructions on the internet to get peoples installation tricks off of a Jeep site. The customer who had this box before me likely gave up due to the complexity of the removal of the old units and likely sent these back to Etrailer (not Etrailer's fault). 162442

These are the second set of Timbren SES I have purchased, the first being for a 2006 Nissan Titan and these for a 2013 Dodge Ram. Both were purchased in order to pull a fifth wheel camper and minimize the "squatting " issue. I am very pleased with the result. Installation on the Dodge was literally a 5 minute breeze as there are no nuts and bolts to remove. Just popped out the old ones and pushed these into place. Lowering the fifth wheel onto the bed secured them into place. The ride is impacted slightly when not pulling the camper, but as these install so easily, I will be able to put the OEM parts back into place with ease when not towing to soften the ride. I highly recommend for anyone pulling heavy loads. 87257

Hi Jerry, you just reinforced my decision. My wife bought a 7000gvw horse trailer bumper pull, so my lil 2wd ram short bed swatted at the sight I bought and installed these ant the tow levels changed immediately. The empty weight can be a bit jarring and I was considering the same, take them out for the next 3-4 months winter in mass. And stick em back in in the spring. Glad I saw your review. Thanks, Mort T

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


The Timbren rubber springs are a great addition to the truck 2013 Super Duty Lariat Crew Cab 172" 4x4. The truck has the 20" wheel option which requires the factory to place a 2" leveling block up front. That makes the truck level of course, taking away the rake, however in doing so makes it look like it's squatting when loaded. Before installing the Timbren springs I loaded the truck with a pallet of pellets and the wheel well sat at 38 5/16" from the ground. After the installation the same load was placed in the bed and the wheel well measured 39 9/16" from the ground. The Timbren springs saved over an inch of squatting meaning more weight on the front for steering and breaking. The ride improved from the motion of the ocean leaf spring ride while pulling our travel trailer to a more smooth but firm at the same time feel, a better ride than empty which does not engage the Timbren springs. This product is the fraction of the price of air bags and far less complicated/ less parts and things to go wrong. One of the original bump stops gave me a hard way but wasn't too bad. I installed the Timbren springs 19 March 2016. 373655

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Having purchased a cargo trailer, I thought it might be wise to beef-up the rear suspension on my 2000 Tacoma. I found the Timbrens on etrailer, and it sounded like they might work well, so I purchased a set and installed them. According to the instructions, there should be about a 1/2" gap between the top of the springs, and contact with the bottom of the Timbren - unless you have a CAP on the truck! The gap pretty much evaporated because of the fiberglass Leer cap. So, I'm getting contact a lot of the time. Result is, my ride has become stiffer than I'm used to, but not so much that it bothers me. Like my wife said, " It's a truck! Hello!!" (OK, I'm satisfied with the product.) 110248


Comments

Keep in mind that the gap Timbren refers will diminish as the springs wear. Since the truck is a 2000, it probably has some miles on it and if it has hauled heavy loads in the bed or has pulled a trailer, then the leaf springs may just be worn.

A year later and 5,304 miles pulling the trailer, I think the Timbrens are a good investment. With a typical pull of 2,555 lbs of trailer and load, and approximately 300 lbs of tongue weight, Im finding the truck actually rides better than it does with no load. And, theres no maintenance whatsoever!

Product installed easily into 2015 Honda Pilot Touring 4WD. Both sides took a little over an hour to install. I've noticed minimal ride quality difference when not under load, and a stiffer ride under a 430 pound tongue weight but less sag in rear suspension. 259855

Etrailer did an excellent job. 2 day shipping for less than $8. No brainer. Staff was helpful on the phone answering questions. I ordered online and that was easy as well. Product: these went on 16 F150 4x4 supercrew with tow package and e rated upgrade tires. I use the vehicle to pull 7000 lb travel trailer. Purpose for the purchase was to help with sway and slight sag in the rear. I use a wdh with sway but that was not performing good enough. I choose these after some research. Install: easy. I didn't use a jack or lift. I just assembled with one inch spacer. I had an inch between the bottom of the timbren and the stop plate. I am no mechanic. Unloaded was pretty much what I expected. You hit a big bump, you get some jarring. 90% pleased. First tow with 16'6" boat (full windshield). The timbren was not engaged from the weight of the boat. Bumps were a little ruff. Added weight from equipment will take care of the space and ride should be better. 85% pleased with towing the boat. Travel trailer tow. Almost completely leveled truck with combination wdh and timbren. Was able to comfortably tow. Took out most of sway I had experienced. Almost 0 bounce, even at low speeds. Basically did everything I wanted it to do. 95% pleased. 4 stars because the unloaded ride is stiffer than I would like and pulling the boat maybe a tad ruff without equipment. This will be especially true in ruff roads. But at half the cost of air bags and ease of installation I do think they are worth the money. Would recommend to those that do not mind a rougher ride every now and then. 377432

This is the second time I purchase and install these, the first was for my 2013 F150 and now on my 2017 F150. I towed my 9600lb bumper pull RV with the new 2017 truck before i ordered this second set, just to see if i noticed the difference. I loved the last set but heck, life is about experiences right? Those of you who have these are laughing right now as you know what I'm going to say. HUGE difference, noticed the absence right away. Got home from that camping trip, straight on my computer to order this latest set. As far as I'm concerned this is the best $200 bucks you'll spend. You have extra cushion when it matters most and it doesn't affect your ride at all when you don't. They are very easily to install and you don't have all the extra equipment etc as with an airbag system. I'm not the kind of guy who works on his truck, I don't consider myself mechanical at all yet i didn't have any problems with the installation. The only "issue" i had was when attaching the stop bumper to the metal mount. The screw is just long enough so i could get the tension i needed to get it threaded (the head of the bolt would drop slightly within the socket). I was able to get it threaded by using my index finger to hold the bolt and my ring finger to turn it, just enough to get it started. After that I was fine. As i mentioned, I'm not mechanical so my tool options were limited. Just bring some patience with you and you'll be fine. The instructions are good. As long as I'll be towing a camper, I'll have a set of these on every truck I own. 400940

Self Installed on my 2017 Super Cab F150 4x4. Stock unloaded ride height was 9 3/4" clearance from top of tire to bottom of rear fender arch. I pull about a 5500 lb travel trailer with WD hitch. This lowers ride height by 1.5" to 8 1/2" clearance. Installation was straight forward, only issue for me is that the lower bracket that goes around the differential/axle was unpainted raw steel. I shot some matt black enamel on it to help with rust before installing. I did not use the extra rubber disc, as there would of been only about 3/4" of axle travel unloaded and I did not want an overly harsh ride. A test drive unloaded, showed that the ride was only slightly more stiff, and not enough to make much of a difference of a stock ride without. There is about 2" of gap or free travel of axle to rubber stopper when the truck is unloaded. Loaded/towing my trailer, the ride was improved over stock -no Timbren. I have about 1 " of travel before contact is made with the rubber stoppers. This smooths out the 'bucking" or sway motion that you can sometimes get while towing on uneven surface roads at speed. I would only recommend adding the extra rubber spacer disc if you regularly carry a large payload. This is a good product for a great value, that will make your towing, or load carrying more comfortable and safe. I would've rated 5 stars except for two reasons: the unpainted brackets and the thread area on the rubber mounts that is fully loaded with paint and makes threading the rubber mount bolts more difficult than it should be. 472157

First Trip with my new Rockwood Extreme Sport to San Diego went well although I had a lot of sag in the rear. Camper place said I did not need a weight distribution for my 03 Jeep Liberty so I got online and found the TJRL4. I ordered it and had my mechanic put them in. We had to call the help desk as they were slightly to big to pop in so he had us shave the top down a bit to fit. My last four trips with the TJRL4 on my Liberty have been outstanding, sag is not an issue and a much better ride. I think if you do not do a distribution hitch , this is much easier way to go. It raised my jeep up slightly also without the trailer on so that is a plus too. The main result was I feel very confident pulling my trailer with a Liberty which went from Arizona to Montana and back, up hills, down hills etc with no problems at all and I was in total control at all times. I credit this to the way the TJRL4 corrected the sag issue. Great Product. 410027

Fast shipping. Installed the Suspension Enhancement System myself in about 35 minutes on my Tacoma. Very happy with the result! Truck leveled nicely and SES definitely added noticeable stability with a 3200 pound travel trailer. Great staff at e-trailer! Couldn't be more pleased overall! 130274


Comments

Since purchasing the Timbren Vehicle suspension product I have towed my 3000 pound R-Pod travel trailer, with a 4 door Toyota Tacoma 4.0 6 cylinder, 2 WD several times and could not be more pleased. The product was very easily installed by me, with a cup of good coffee and about 35 minutes and has performed very well. With my light trailer and this product, I did not feel the need for a more expensive and cumbersome weight balancing hitch. I would highly recommend this product to anyone with a similar towing situation. Hooking up the trailer is quick and easy with nothing extra to do! When not towing, you dont even know the axle bumpers are there. They also come into play when carrying a heavy load in the bed. Thank you very much for checking back.

I just purchased a 2018 Chevrolet 3500 drw to replace my 2015 truck that was identical. I had air bags in my previous truck but decided to give the Timbren rear enhancement system a try. I watched the video about them as well as the install and decided that for the price as well as the ease of installation that I would give them a try. my only reason for using anything on the rear suspension is to eliminate the added "squat" that these trucks are known for. Ordering was simple, I called with a question and spoke to Angela, not only did she cheerfully answer my question, but also offered to place the order for me. I took her up on the offer and after completing the call I had an order confirmation email, and within 30 minutes I had a shipment confirmation email. I have ordered from Etrailer a few times and I must say that they are one of a few companies that I never worry about having a bad experience, they are always on top of their game. I received the product within 5 days using the free shipping. I installed them on Saturday, and to my surprise it was as easy as the video shows, within 20 minutes I had both sides installed and was cleaned up and hooking to the trailer. I was thrilled when I hooked up and checked the level on my trailer to find out that I was sitting exactly at the height that I did with 50#'s of air in the airbags on my other truck. I jump in and take a run around the block, making sure I hit a railroad crossing and I will say I am very pleased. Great job Timbren, Angela and Etrailer !! 499444

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


This Timbren SES kit is quite complete and seems like a great way to help the old springs in my '95 Dakota. My research shows the theory is correct anyway. I just finished the install and will have to give it a real test in a few days. I didn't even have to raise my truck as recommended in the instructions and was able to do it all laying in my driveway on my back. The install took much longer on the first unit as I could not get them to properly tighten up to the frame. Not being able to see directly what the issue was, it took me a little while to discover the Grade 5 bolts supplied were about 5/16" too long for my application. Fortunately I have a lathe and was able to machine them down rather than going to a big box store to buy replacement hardware, most likely of suspect quality. Someone else may not be so fortunate. The unthreaded shank portion of the stock bolts still needed two washers to be able to adequately tighten them through the frame and beefy plates on the SES. Once I got all of the bolts shortened and determined the correct amount of additional spacer washers needed (2), they went right together. I spent over an hour on the first side, but the second side was done in 15 minutes, as I expected. Perhaps my situation was unusual and I was accidentally supplied the wrong hardware. If the 1-1/2" long bolts are standard for this kit, the Dakota frames are too thin (about 1/8" or so) to to use this long of a bolt. A 1" bolt would be more appropriate for this application. 81456

Installed the Timbren SES suspension aid on a 3500 Sprinter-based Winnebago motorhome. The ride/handling around town is improved - but have not experienced highway use yet. Installing these is very difficult. Required 4 hours for frustration and hard work. You must install one end of rubber mounting tab into bracket on frame and then "work" other tab into the frame bracket using large screwdriver, small wrecking bar, or both. Timbren recommends soapy water - others have used silicon or WD40 (which Timbren does not recommend). It would be nice of the instructions provided more detail on installation technique. 57832

I am going to install the Timbren MBRSP35A - Rear Axle SES Suspension Upgrade on my RV, but until they arrive, I re-installed the original that I took out for dimensions. I did quickly discover the difficulty of re-installing it, but also found a trick that helped and once found it installed fairly easy. As mentioned above, install one end of the rubber mounting tab into the bracket on the frame. Next, dont try to get the opposite tab in all at once...start with the inside corner of the tab, and with a large screw driver, begin working from the inside towards the outside, stuffing it just a little at a time...no soap, no lube...it just slipped right in.I hope that helps. I think the MBRSP35A - Rear Axle SES Suspension Upgrade will even be easier because you at least have the full body to grip and apply pressure as you work the screwdriver.

2010 Nissan Frontier with Timbren suspension components. Trailer is a Jayco X17Z with close to 450lbs of tongue weight. Pictures are a before and after view of the rear suspension droop. 52393


Comments

Since the Timbren install we have towed the camper on back roads with stop and go traffic as well as on the highway at 65 mph. The Pro4X does ride level and handles the added weight well. I wish I had a longer wheel base and a tandem axle trailer as on occasion we develop a slight up and down oscillation until the suspension settles down. It is noticeable when driving over long bridges. This is mainly due to the truck setup and not the Timbrens. We had this problem before the install and the Timbrens are making a difference.I have also hauled an estimated 780 lbs of hardwood flooring in the bed at 65mph and the truck handled it with no problem. It remained level and stable.

-- comment by: Rick S - 01/29/2013

You might be able to adjust the tongue weight of the trailer and get that oscillation to settle. You want your tongue weight to be about 10-15% of the trailer total weight. Also if the trailer does not ride level, looking into getting a different drop length ball mount that will get the trailer level or even slightly nose down.

The timbren did a great job on my 2012 RAM hauling a 28' travel trailer. When the truck isn't heavily loaded you'd never know they were there. Once loaded up they stop the dreaded saggy RAM butt and keep the truck much closer to level without complicated airbags. I moved them onto my new RAM last year and they're just as successful there and I'm fairly certain will prevent the premature rear shock failure that occurred on my 2012 that came as a result of squashing the rear end during backing of my travel trailer after the Reese weight distributing hitch (also recommended) was disconnected for tight corner backing into campsites. Also prevented dropping the RAM too low if heavily loaded with lumber or whatnot as the original stops are very soft and will bottom out your shocks. If you occasionally find your RAM sitting on the rear bump stops, don't overthink it, just buy these. You'll still hit the stops, but they'll be sturdy height maintaining stops instead of a squishy shock busting stops. The ride gets a little bouncy when you're bottomed out on the timbren, so if you're looking to run your RAM at full capacity over long distances you'll probably want to get airbags or springs. But for occasional heavy loading for short distances these can't be beat in quality or price. Also etrailer was helpful in finding me a solution to use these on my 2012 Outdoorsman RAM which has a slightly higher ride height than the standard RAM. 512990

I read the recommendation to another buyer and decided to try this product on my 2012 Ford F250 Superduty. I needed help for my 25' goose neck trailer. EASY to install. Worked perfectly with 15K of hay + 6K of trailer weight. The rear of the truck barely set down on the factory overload springs. Empty ride does not seem to be affected as the Timbren pads do not contact the overload stops. Thanks for a perfect solution without great cost and installation hassle! 62416

I had trouble with my browser called and spoke with Karen. She took my order. Then turns out I had two orders of the same thing. Karen took the time to call my home and ask is I really wanted two of the same thing. Great company, great customer service. How many companies in today's world would have made the extra effort. This is the second pair of Timbren I have bought. I love them. Used them on a 2010 Silverado, and now on a 2014 Express Van. Not only help the 'bottoming out' effect, but great for stability during towing and when fully loaded. 146117


Comments

After a year I still like them for heavy loads. I have found the bottoming out when hitting a bump with no load painful and uncomfortable. I actually cut two coil off them to allow the normal suspension to work when having no load. They still work for heavy loads. They are not the panacea for suspensions, but they definitely work when you have a heavy load.

I bought these for my Xterra to help eliminate sag when towing. I don't tow a lot and I liked the idea that these units wouldn't affect the ride the rest of the time. First impressions of the quality. The thickness of the steel brackets is great almost look heavier than they need to be. The rubber springs are very solid and seem like they will last a long time. The included hardware seemed to be of good quality as well. My only complaint was the finish on the brackets. At this price point I was hoping they would be powder coated but they are painted. Not a huge deal but right out of the box some of the paint was flaking off like the parts weren't prepped properly. I ended up scuffing them down and spraying two coats of bedliner on them. I am hoping that will help keep them rust free. Installation was very easy and I had no problems getting them pretty centered over the axle. I did have the opportunity to tow since the install and they really did make a huge difference. I gained about 2 inches of height when fully loaded. The ride of the vehicle was very good and the handling was very stable. I drive this vehicle every day and when not towing it is a little stiffer at times, but certainly not enough to be a problem. I am at 60k now and plan on replacing my shocks shortly so I am hoping that will help. Overall, it was a worthwhile upgrade and I would do them again in a minute. 399984


Comments

These are still holding up great a year later. I’ve pulled a loaded trailer twice in the last month and it keeps the Xterra perfectly level. I have not noticed any harshness in the ride with a loaded trailer, but when not towing it can get a little bumpy on rough roads. Not enough to cause any controversy problems and I still think these are an easy solution.

I drive a 2010 Chrysler Town and Country and tow a pop up camper. In addition to that I also carry my wifes 200 lb power chair in the back of the van. Needless to say the back end of my van was bottomed out. That caused the front end of the van to be up in the air thus giving me less control of the front wheel drive vehicle. After installing a new set of shocks and the Timbren rear suspension on my van What a difference it made. I was a little concerned about the price but the results outweighed the price by a longshot. Now with my wifes power chair and the pop up hooked up, my van sets perfectly straight and my vehicle has better control making the trips a lot safer. The best thing is, I did it all myself and saved a ton of money on labor. 239323

I was pleasantly surprised to find the installation procedure to be even simpler than the instructions sent with the "Timbrens". So easy even a cave man could do it. Same with the mirror extensions, very simple to install. I can't provide useful feedback (or a meaningful rating) regarding how well these products work. I haven't had a chance to use either the timbren system or the mirrors. My first trip with the trailer will be late September. I'll let you know when I get back....thanks. Dave G 99667


Comments

Unfortunately, I ended up returning the timbrens and replaced them with the Firestone Air Shocks. The Timbrens worked fine when hauling the trailer. However, without a load on the truck, the timbrens prevented the shock absorbers from engaging when needed and the resulting ride was very uncomfortable. The air shocks are the way to go if you only need the extra suspension on occasion. Thanks. dg

These "enhanced" bump-stops have definitely improved the ride quality of my 2013 Ram 1500 quad cab when pulling our 7500 lb. 29 foot travel trailer. The trailer probably has 500+ pounds of food, clothes, kids toys, etc inside as well. The truck bed probably has another 800'ish pounds of equipment in it that compresses the suspension before I even hook the trailer up. With the stock stops the rear suspension hardly moved. After adding the new stops, the rear suspension had travel again and the steering felt less twitchy. Unloaded truck will hit the new stops only if I hit a pretty harsh bump but it's only noticeable if you're paying attention to it. With a loaded bed (no trailer) hitting the stops is more noticeable but you still need to hit a decent bump for them to touch. They are very easy to install. Take the time to read the instructions and watch the installation video before you pay someone $50-$75 for a 15-20 minute job. I would buy them again. 482362

I have a 2013 Chrysler Town &Country that I load down with a roof and a rear rack storage. I was having issues with the rear sitting so low that I couldn't see the top of the rear tires and would occasionally bottom out. Now that these Timbrins have been installed I lose about 3/4 of an inch ride height compared to the 3+ inches I was losing before. It's still a little too early to determine if I'm completely satisfied, so I'll try to provide an update after traveling from Houston to Michigan and back during the holidays. The ride is definitely more firm(when loaded down with the extra storage), which is to be expected, but wouldn't call it jarring. The wife and kids will let me know soon enough. ;) One thing to note about the installation video linked by etrailer in regards to these Chrysler/Dodge minivans... I don't have access to a full vehicle lift, so I had to use a coil spring compressor to pull the coil springs, which is not a big deal because they can be rented(for free with some places) from your local auto parts store. But, they don't just pull out like the video suggests. Also, as others have recommended, disconnect the shock from the bottom, NOT the top. I'm not a mechanic, but not a complete novice. I experienced a few hiccups from following the etrailer video, but was able to work them out with the right tools and patience. 459059

I have a Half-Ton Jayco Eagle Lite 5th wheel. My brother installed Timbren SES on his truck and with his encouragement, I purchased a Timbren SES from eTrailer. It took only 20 minutes per side to install. Before Timbren, my truck suspension would lower 2-3 inches with the 5th wheel. After Timbren, my vehicle is perfectly level at all times, the ride is very smooth. I strongly recommend this product to anyone that needs to enhance their vehicles' rear suspension. A great product. My only regret is that I did not make this investment sooner!!! Frank P., Chattanooga, TN 133107

This review is on a timbren air spring ,I bought this on a Saturday night ,went out of town Monday morning and got in on Thursday afternoon ,wife said the box had arrived Tuesday and put them on this morning on our 2006 Chevy k-3500 ,my guy had the truck in our shop for an oil change and I asked him to put it on, came back 45 min later and he was done with the spring installation and the oil change ! I asked him how hard it was and he said it took him longer to figure out which parts in the kit he needed that the actual install ,said it was about as easy as it gets .Well ,now for the test drive we drove the truck empty ,pretty much as stock ,rode real well.Then we put a Gaylord box that weighed 4506# and drove the truck ,WoW ,What a difference ,truck rode great and handled well ,went over railroad tracks,really handled well and rode great ,I wish I'd have done this years ago ! I highly recommend this product and commend etrailer on their good service and what made me decide to purchase the timbren product was the you-tube video ,after I saw that ,I placed the order ,it looked so simple to install and it went on just like on you-tube 283142

Received the product promptly arriving yesterday. Was a little hesitant to take off the u-bolts on the axle but they came off with no problem and went back on easily. It made installation easier by removing the wheel on each side as I was installing them. The Tacoma will now hold a good load without the sag. Have had previous experience with this product with very good results. The truck now has no dip or sway when driving on rough road. Very good product for a firm and stable ride. 105069


Comments

The product is still working very well. The Timbrens give a very stiff ride when the bed is not loaded, actually a rough ride. When the bed is loaded or pulling a trailer is where the value is most notable. On the Tacoma, the frame rests on the Timbrens even before a load is applied. I dont mind the rough ride so they have worked out very well for me.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I ordered these on July 4th (Wed) and received them on Friday. As always I got very fast shipping from etrailer.com. I installed these today on my 2009 Sierra 1500. I pull a 20ft enclosed trailer all around the mid-west and up and down the East cost. I've continually been adding things to the trailer so lately the rear of the truck has started to sag a bit when towing. This product seemed like a reasonable way to help remove the sag. I measured the truck in a couple of places near the back with the trailer hooked up prior to installation. After installation the sag was reduced by an inch to inch and a half which is what I was looking for. The truck is now very level with trailer attached. Installation was very easy as the mounting point is easy to get to. I did one side at a time by jacking up that side and removing the tire/wheel. I probably could have done it without removing the wheel, but this just made it that much easier. Remove one 10mm bolt on the original bump stop and then bolt on the new part. Tighten and you're done (well, I had to put the wheel back on, etc.) I did the whole thing in about 40 minutes. I haven't pulled the trailer yet with these installed, but I've already gotten the primary result out of the purchase which is to remove the sag in the truck when the trailer is attached. 47122

Purchased for a 2008 5.7 l Toyota Tundra. As advertised. Installed in one hour. Performed as described with an unload bed- slightly stiffer with less recoil over rough roads. Hitched the fifth wheel to the Tundra and took a one hour trip over varying road conditions. Performed exactly as I hoped. Couldn't be happier. ETrailer processed the order on the same day and I received it on the afternoon of the third day. Could not be more pleased. 109677

Thank you for your follow up inquire on the Timbren suspension parts for my 2008 Tundra. I used the vehicle for the past year to tow a Heartland fifth wheel. The parts worked as advertised and I have been happy up til I sold the Tundra. The service I received at Etrailer led me to purchase towing base plate and bar for my dinghy on our next RV. Its a pleasure dealing with Etrailer!

2017 Raptor SCREW. With a 100+# tri-fold tonneau cover, full tank of gas and no cargo the axles will be slightly up against these modified bump stops. That being said the vehicle is still soft over pot holes, small curbs, etc. The vehicle doesn't squat anymore under launch and the back end handles more like a standard F150 with a tow package yet no where near as hard as an unloaded F250. With 9,400 pounds of boat and 800 pounds of tongue the rear only sags about an inch from unloaded. Installation is straight forward and a ratcheting boxend will speed up the process. The design will also allow you to uninstall these as needed for off-road trips. For my purposes they will stay in year round. 448657

I am writing this shortly after completing the install so I am trying to tone it down a bit. Reviews of this product install suggested 20-30 minutes to complete. It took me about 90 minutes. My biggest initial concern was removing the factory bump stops. I soaked the bolts with liquid penetrant a few days before the install. The bolts came out easily. The bolts which attach the rubber spring to the bracket would not tighten completely. The nut is tack welded to the underside of the mounting plate. On both brackets, the nut was not centered on the hole and the tack weld deformed the nut. I had to chase the threads first to be able to install the bolt and complete tighten the rubber spring. One of the brackets was labeled left with an arrow pointing to the front. The left side terminology in the instructions could be more clear with driver side notation. Overall, this should have been an easy install. Product quality could be better. I am a bit concerned with proximity of the brake lines. I will have to seen what it looks like when loaded. Performance when loaded still to be evaluated. 528960


Comments

I took a look at your photo and I can not tell if the spring is directly above the axle but if it is, the spring will hit the axle before it hits the brake line. There are elongated holes in the brackets that allow for some adjustment. The best thing you can do is move the spring as center over the axle as possible.

Product arrived a day early!!...install took 15 minutes. Worked as advertised, stiffened up the rear end of my truck and made the ride while pulling 8000lbs of travel trailer much smoother. Worth every penny!! 199349


Comments

I have a T.T. 8,300 max. loaded rating, am usually 8,000 like you with 825 lbs tongue weight, have Sherline tongue scales. Went from 1998 Ram 2500 HD suspension 60 leaf springs. 312/15 got 2015 Ram 1500 with coil springs. Truck is loaded to capacity. When hook up trailer got really serious sguat to it. I tow at 60 to 65 max. Stay at 60mph for better fuel economy with V-6 Ecodiesel. Have only towed 767 miles avg. 18 mph. Nick did you by chance take measurements before and after on your truck squat. I use Reese weight distribution set up. I am still tweaking my W.D. set up, new truck sit about 1.25 to 1.5 lower than old Ram 2500. By the way what are you towing with ?

I did not write down any measurements before or after spring install sorry. I have a WD hitch as well by EZ load I pull with a 2013 Ram 1500, 5.7 L Hemi. Sorry I couldnt be more help, I took measurements when installing the springs but I didnt write them down and its been a few weeks so I dont remember. My recollection is that they took about 0.5 inch of squat out, and the ride was MUCH smoother.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


A year ago, I added Timbrens to my '09 F350 to help carry a '09 Lance 915 camper. Since my truck is a CC LB diesel model, the truck payload and loaded weight of my camper are similar. I found the Timbrens a cost effective way to limit the suspension sag and improve truck/camper sway. When unloaded, I rarely notice the Timbrens as they are ~1.5" away from the spring pack stop and only engage on large bumps. I also like the maintenance free aspect of Timbrens. To further enhance the loaded ride, I am replacing the thin factory contact pads on my overload springs with larger ones. I found that adding the Timbrens limited suspension travel such that it prevented adequate overload spring engagement with the factory pads. The replacement overload pads from Torklift and Supersprings are 3" (too much IMO as they contact the overload spring nearly all the time making for a rough ride). I am cutting down a set of Superstops to ~1.5 - 2" for the right amount of overload spring contact and Timbren engagement but still maintaining unloaded ride quality. 570372

I installed these springs on the front a 2002 Ford Excursion with a 7.3L diesel. The kit has excellent fit & finish. It was very simple, and straightforward to install as well. If you can put a nut on a bolt, and change a tire you can do this. The hardest part was the bolts on the drivers side due to the tight area between frame, suspension, and axle parts. The passenger side was very easy. These replace the factory bumpstops between the framerail, and axle. They have stopped the heavy engine from bottoming out the suspension when hitting severe bumps, and do so without making the ride anymore harsh than before. I definately recommend this product. 10906

Product requires removal of coil springs, sway bar, original stop bumpers, and wheels to install. Product contacts lower swing arm when installed and not under a loaded condition. Increases stiffness in suspension and also creates a rougher ride and increased road noise. It does prevent the typical sag in the rear suspension. There is no gap between the newly installed Timbren rubber and the vehicle suspension when installed and the normal weight of the Pilot as per instructions indicate there should be. 121754

Suspension is solid! Vehicle rool on turns is gone, towing an enclosed 16 foot cargo trailer is a breeze! Nice product and never have to worry about loosing an air line or bag because this system is simple and solid. Keeping it simple!!!

Installed on 08 Mariner, same vehicle as second-gen Escape and Mazda Tribute... Only 2 bolts, but WAIT, there's MORE!!! Be aware that you need to do a full rear suspension R&R (upper arms, lower arms, shock bolt, brake caliper and a pair of brake/ABS lines). THEN you get the chance to access and replace the OEM snubbers with theses. All said and done, the second side took considerably less time to install. One of those jobs that by the time you figure it out you're done and hope to never have to do it again... Value? It's in the eye of the beholder but suspension upgrades of any sort for these vehicles is few and far between. The Mariner is an '08 with 92,000 miles and we are now taxing it with a pair of German E-bikes (about 45 lbs. each) along with a very STOUT German bike carrier. (Lived/worked in Germany for years.) Mounts on our 2" hitch and the rear was sagging/swaying more than my Wife and I cared for on the road. Seems to have eliminated at least 90% of the sag and sway when loaded and actually seems to make contact when unloaded on some of our poorer local streets with corresponding ride improvement. OK, my Wife noticed immediately and thanked me for "making her Mariner ride so nicely now"... 398147


Comments

Continues to work well, passed the Mariner on to our Son in Louisville, KY cross-country drive, returned with a new Crosstrek. Streets arent nearly as decent as our area of North Cali...hope the car survives!
