Reduced axle sag with Timbren suspension enhancement

Just like the rear of your GMC Sierra will sag under the weight of a fully loaded bed, the front of your vehicle will sag when under the burden of heavy equipment such as a snowplow. In this case, the front axle is handling not only the weight of the equipment, but also more of the vehicle's weight. Overall GMC Sierra handling - traction, steering, and braking - is negatively affected. But the resistance from Timbren's Suspension Enhancement System works with your factory suspension to keep your vehicle level and improve your driving experience.


Install diagrams of Timbren hollow rubber springs

The Timbren system comes with custom-fit brackets that are bolted onto each frame rail above your front axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down so that the bottom of each spring touches the axle. Because each spring is making constant contact with the axle, it is always working to cushion and support your factory 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 increases resistance, stiffening the suspension and keeping your GMC Sierra level.


Timbren suspension system works to prevent body roll

Each hollow rubber spring works independently to support the driver's-side or passenger's-side of your GMC Sierra. 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 you're carrying 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 help raise the front end of your GMC Sierra when you're using heavy equipment like a snowplow. This ensures that your 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 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 because the rubber springs work to prevent bottoming out on rough roads.


Timbren Suspension Enhancement Compared to the Competition

Timbren's Suspension Enhancement Systems are much easier to install than air springs - there are no air hoses to run, no compressors or gauges to hook up, and no manual adjustments to make. The rubber construction makes Timbren's springs more elastic than similar products constructed of microcellular urethane. More elasticity allows for a more comfortable ride because the rubber has more travel.

Video Transcript for Timbren Vehicle Suspension TGMFK25S Review

Today we're going to review part number TGMFK25S. This is the Timbren Front Suspension Enhancement System. This is a custom fit part number, this is designed to fit the Chevrolet and GMC vehicles starting in 1996. What I would recommend since there's many vehicles it will fit on, I would recommend to go to our website and on the Use Our Fit guide and put your year and model vehicle and that will show you if this part will work for your application. This kit will improve your suspension and handling, prevents body roll with improved weight distribution. It does stabilize the vehicle for better handling of heavy loads. It does adjust progressively to road and the load so you always have a smooth comfortable ride and it does provide additional support as needed.

It does allow the spring ample movement while at the same time providing cushioning for light loads. It does increase the stability and gives you great performance while cornering, swerving or hauling large loads. This does take the brunt of the bumps in the rough loads and it does extend the life of your vehicle's suspension. You do have to make sure, though, it is designed to work with a suspension system that is in good working order and this system does not require any air hoses, compressors or manual adjustments. This part includes everything shown here on the table. It includes these two Aeon hollow rubber springs. It includes these specific brackets and the hardware for simple installation.

When you do install these, it comes with a nice set of instructions that are pretty detailed. These will replace the axle bump stops on your frame, there's no drilling required. The capacity on these is 14,000 pounds but you do need to remember you do not exceed the vehicle's weight carrying capacity. Again, as I mentioned earlier, these are designed to work with a suspension system that is in good working order. This does come with a limited lifetime warranty. That should do it for the review of part number TGMFK25S.

These are the Timbren Front Suspension Enhancement System. .

this is the 3rd replacement of bump stops for my 99 chevy 3/4 HD 4x4. Two were OEM , and one an after market ( lasted a week ! ). I am impressed that the Timbren bump stops are well made and were a direct fit. The truck sits about an inch higher in the front end and best of all the ride is smoother . the truck also has new up graded shocks and the over all condition of the suspension is very sound. the shocks were installed prior to these new bump stops. I would give 5 stars however I am waiting this out to see what the Timbren bump stops are capable of in a year from know. my truck spends most of its time on road not off road . 254821

I would buy again . these are worth 5 stars.

2003 Chevrolet Silverado


My 03' Chevy Silverado really benefited from the installation of the Timbren bushings. Shipping was fast the instructions from E-trailer were very helpful and made it easy to DIY. The front end of the truck seemed to be sagging especially when the plow was raised even with 600 lbs of ballast. The front end was raised up about 3/4" after the install and the ride quality is greatly improved overall. I cannot hardly wait to try them with the plow. I would highly recommend Timbren bushings to anybody with a higher mileage vehicle like mine 160,000. 302726

Chevy 2500HD Silverado


Timbren SES heavy duty jounce bumpers dramatically improved the ride of my Chevy 2500HD and it drops only a very small amount when I hoist the plow. Less than 1/2" dropbin ride height with the plow raised. Yet the riee is not harsh. Excellent product, wish I knew about it years ago. 165956

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

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


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


Comments

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

Patrick, Im still using the suspensions with and without towing. They work just as they are designed to. Very happy with them.

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

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

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

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

Thanks for the question Luc. I used Monroe Sensi Track shocks. They also have built in springs to aid your suspension and will automatically sense your load. Best part they are reasonably priced for the shock you get.

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

  • Rear-End Sag in 2004 Silverado 2500 4X4 Crewcab With Weight Distribution System Installed
  • The best way to fix rear-end sag when towing your 7500-lb trailer with your truck is to use a weight distribution (WD) system. Rear axle suspension helper kits, such as Timbren jounce springs or air bag kits, are better for times when you are carrying a heavy cargo load in the truck bed. These will not give you the same benefits as a properly-tuned WD system when towing a trailer. In fact, if jounce springs or air bags are used along with WD, then they can sometimes interfere with each...

  • The Timbren front-axle jounce spring suspension kit you referenced, part # TGMFK25S, is a fit for both 2WD and 4WD versions of the 2004 Sierra 1500 SLT. These bolt-on without any drilling required (using included hardware) and replace the factory bump stops now on your truck.

They are not intended to be an alternative to replacing a worn or damaged suspension....

  • Will Timbren Suspension Enhancement System Allow 2006 Chevrolet Truck To Sit Higher w/ Plow
  • The Timbren Suspension Enhancement System, part # TGMFK25S, will prevent the front end of your 2006 Chevrolet Silverado truck from sagging so low when a plow is mounted to the front of the truck. This system is designed to work with suspensions that are in good working order. I have linked and FAQ and instructions for the Timbren Suspension Enhancement System, part # TGMFK25S. I have also linked a video installation of another model of the Timbren Suspension System, on a different vehicle...

  • Front Suspension Enhancement Recommendation for 2006 GMC Sierra 3500
  • The Timbren kit part # TGMFK25S that you referenced is a confirmed fit for your 2006 GMC Sierra 3500 but it's for severe duty applications so for you it would be very harsh. It would give you the support you want but at the cost of a very harsh ride quality. A better option would be the Air Lift AirCell part # AL52212 which gives you the support you would need but isn't as stiff so it wouldn't be nearly as harsh riding. This spring is 3.15 inches tall. There is also a small wedge as...

  • Is there a 12-Volt Accessory Circuit on the 7-way of a 2011 Ford F53 RV
  • Yes, there is a 12 volt power source on the 7-way that is on your 2011 Ford F-53 RV. It will be on the 11:00 position of the connector as you look at the front of it. Check out the picture I attached that has a picture with all of the terminals of a 7-way labeled with their functions. You might want to test for voltage on this circuit with a Circuit Tester # 3808 as well just to be sure. I also attached an FAQ article on trailer wiring that you might find informative.

  • Recommended Front Suspension Enhancement for 2002 Chevy Suburban 2WD 1500
  • For the front suspension of your 2002 Suburban, I'd recommend the Timbren Aeon Springs, part # TGMFK25S. Installation is straightforward. You'd remove existing bump stops, and use the hardware and existing holes to instal the rubber Aeon spring. The springs get progressively stiffer as more weight is added to them, they typically come into play when a plow or some other very heavy piece of equipment is installed on the front of the vehicle. I'll link you to the installation instructions.

  • Recommended Front Suspension Enhancement for 2007 Chevy 2500 with Snow Plow
  • For your heavy snowplow, I recommend the Timbren Front Suspension Enhancement System # TGMFK25S over the Air Lift AirCell Custom Helper Springs Kit - Front Axle # AL52212. The Timbren Aeon Rubber springs are simply stronger and they work in the same way as the helper springs, yet offer more support on the front end, so that first inch gets support.

  • Suspension Enhancement System Recommendation for 2003 GMC Yukon 2 Wheel Drive
  • When it comes to a suspension enhancement system for your 2 wheel drive 2003 GMC Yukon, you will want to go with the Timbren # TGMFK25S. This system uses hollow rubber springs to absorb the brunt of the force on the front of your vehicle which helps to reduce sag and sway for better handling, traction, and a smoother ride. Part # TGMFK25S, for 2 wheel drive, and part # TGMFK15A, for 4 wheel drive, differ in design and installation. The 2 wheel drive version is a bolt-on kit where as...

  • Recommended Suspension Enhancement Kits for 2001 Suburban 2500 with AutoRide Leveling System
  • The AutoRide self-leveling and damping suspension system in your 2001 Suburban 2500 uses various sensors in the vehicle to control a compressor pump that continuously varies shock damping while driving. This system cannot be defeated and aftermarket air springs like the Firestone Ride-Rite cannot be installed on the vehicle according to my contact at Firestone. However, you can install a set of rubber jounce spring such as the Timbren front-axle kit # TGMFK25S and rear-axle kit # TGMRSB4S....

  • Rubber Jounce Spring Suspension Kit for 2006 Chevrolet 3500 2WD Flat Bed Work Truck
  • If you want a suspension helper spring kit that avoids the complication of air springs, then I suggest a rubber jounce spring kit from Timbren. We offer both front- and rear-axle kits for your 2006 Silverado 3500 2WD flat bed work truck. The rear axle kit I recommend is the Timbren # TGMRTT35C which is intended for heavy-duty vehicles. This is a bolt-on kit that requires no drilling. If you want a front-axle kit I suggest Timbren # TGMFK25S, also a no-drill install. The linked article...

  • Timbren Recommendation for 2008 Chevy Silverado 3500HD Towing Heavy Fifth Wheel
  • The Timbren system I would recommend recommend would be the part # TGMRCK35S. It's the lighter duty of the two kits but the heavier duty part # TGMFK25S but it's going to provide a very stiff ride. The # TGMRTT35S still provides the 8,600 lbs of support which will work great. The HD is really needed only in very extreme situations like tow trucks.

  • Timbren Suspension Kits for 2000 Chevy Silverado 1500
  • We have both front axle and rear axle Timbren rubber spring suspension enhancement kits for your 2000 Chevy Silverado 1500 that are displayed on the linked page.

If you are interested in a front axle kit too, in case you use a snowplow for example, you can use Timbren kit # TGMFK25S for 2WD or kit # TGMFK15A for 4WD (if the truck is a 2-door model).

  • Front Timbren Kit Availability for a 2001 Chevy Suburban 4x4
  • The part # TGMFK15A that you referenced will fit a 2001 Chevy Suburban 1500 4x4. If instead you have a 2500 model you would want the part # TGMFK25S. By nature these Timbren kits will not stiffen up the front suspension unless you have a decent load on the front of the truck. Unloaded you shouldn't notice them installed.

  • For your 2004 GMC Yukon XL we have the Timbren suspension kit part # TGMFK25S which fits the front suspension and then the part # TGMRSB4S which fits the rear. Both of these kits act like bump stops except are much larger to make contact sooner than the standard bump stop so that they can provide additional suspension support.

Keep in mind, these springs are designed for the front axle, not the rear. It would be better to use Timbren springs on your rear axle when carrying your camper. For your truck, I recommend the Timbren Rear Suspension Enhancement Springs, # TGMRCK35. Adding a set of Timbren springs to your truck...

  • Spacer Recommendation for a 2006 Chevy 2500HD with a 2 in Lift Installing Timbrens
  • What you would want to use is a Timbren Spacer for Raised vehicles # A25723-90AH00. This spacer is 1 inch thick so you would want to use two of them since you have a 2 inch lift. For the rear you would want the Timbren Rear Suspension System # TGMRCK25S, for the front you would want the Timbren Front Suspension System # TGMFK25S. Since you will need 2 spacers per Timbren and you plan on putting them on the front and rear axles is looks like you would need a total of 8 spacers.

  • Best Brake Controller, Suspension Enhancement, and WD System for a 2004 GMC Yukon Towing 7K Trailer
  • It looks like your 2004 GMC Yukon Denali has a towing weight capacity of 8,000 lbs. You will want to verify this in your owner's manual, but if this is the case and your loaded trailer weighs 7K then you should be good to go. If the 7K weight is without the trailer loaded then this could get a bit tricky and you will be pushing the weight limits of your vehicle. Adding a brake controller, weight distribution (WD), and some suspension enhancement will definitely help to make your towing...
