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 vehicle's factory suspension to keep the vehicle level, thereby improving your driving performance. When a truck bed is loaded, the rear of the vehicle 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 vehicle'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 vehicle-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 vehicle'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 vehicle 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 vehicle. 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 vehicle 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

Hello Patrick....I have attached the Timbren product to my 2012 Dodge Ram and am very impressed with the product. E-Trailer 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


Helped make my decision a no brainer....thanks for the pics they sealed the deal.

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!

Ron L - 05/10/2014


thanks Ron. Great information and you helped me with my decision.

-- comment by: Mike L - 12/28/2014


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?

-- comment by: John T - 05/09/2015


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.

-- comment by: Tony O - 05/27/2015


Ive been debating pulling a fifth wheel with a 1500. What size trailer do you have? What is the weight and pin weight, if you dont mind me asking?

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

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 . 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

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

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

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

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

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

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

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.

Jerry H - 07/10/2014


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


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.

-- Patrick B - 12/18/2013


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

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

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

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

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

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

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


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.

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

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

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 soap, no 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.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

Talked to Cathy T who was very friendly and was able to answer my questions and concerns( went into this being skeptical) Cathy assured me that etrailer was a customer orientated company so decided to take a shot, recieved product 1 day earlier than expected which was a nice surprise,as far as installation it was as advertised took less than 30min and was very easy (tip run bolt on open slotted end (back)most of the way in then slide in it will make it easier to tighten bolt) have not towed 5er to see how they actually work did raise the rear of truck 08 ram2500 td did not end up with any clearance but it does say in instructions that medium and heavy duty trucks will stay in contact feel like they will do the job. Will definitely recommend and make further orders from etrailer thanks 222723

Ken have not had a chance to tow 5er on the road yet,I did have to move it in the storage lot from one spot to another and am impressed that my truck stayed level I looked at the timbrens with the 5er hooked up and they were compressed some should have taken pic the tongue weight according to the website is aroond 1800 its a montana 3400rl hope this helps some, will update after towing waiting to mount new tires also bought from etrailer the provider G rated and has an L speed rating tire they are definitely heavy duty trailer tires and just from looking at them and picking up would say they are a good tire after some mileage will be the true test

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


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.

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


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.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

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

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


what shock did you install on the back?

-- comment by: LUC D - 03/29/2016


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


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

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

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


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.

I ordered these on July 4th (Wed) and received them on Friday. As always I got very fast shipping from 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.

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 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

Here some pictures of the installation of the Timbren Front SES on my 2001 Chevy Silverado 1500 Extended Cab. It took longer to back off the top shock nut to drop the A-arm enough to get the bumper in than the actual install took. Some Windex on the bumper went a long way to get them in too. I got these for better ride height with my Snow-Way 26 plow I got last year. I had 4” above the front wheels (to body) and 15.5” under the plow when raised with stock bumpers. With the Timbren installed I have 5.5” above the front wheels and 20” under the plow now. I’ll see how it rides this week. 24647

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

While these seemed a bit pricey for just "rubber bumpers", these "rubber bumpers" did deliver as a great suspension enhancement and were well worth the money. They installed very easily (just like the video) on my Dodge Grand Caravan. (The only thing I did different was to remove the lower bolt on the shock since it was much easier to get to than the top bolt.) They also performed excellent. With no load or a light load the van drives and feels normal (i.e. no adverse effects) and with a medium-large pop-up trailer the back end of the van sagged very little and it drove very stable. It sagged much less and drove more stable than the OEM parts with lesser loads! My experience is based on driving 3800 miles pulling a pop-up and the family to Yellowstone. Great product, service, and shipping speed from etrailer. 54505

Bought these for my new 2018 Toyota Tundra. On my previous 2010 Tundra, I had installed helper springs and decided to try Timbren's this time around. I bought 1/2" spacers, since I did not want the truck to sag too much. Not sure if you can see in the pictures, but with the 1/2" spacers, the Timbren's come into contact approximately 1/2" to 3/4". They can be a bit rough and bouncy once they come into contact, but no rougher or uncomfortable than with helper springs. Over all I am very happy with how they perform. The installation was very easy. Took me about 1/2 to 3/4 of an hour. All you need is a 24" breaker bar, a ratchet wrench, and a 19mm deep socket. Unloosen the nuts enough to remove the existing bump stop and replace with the Timbren's. That's all it takes! 451415

Installed this on my family's 2010 Town & Country. I was considering installing load-leveling shocks, but opted for these instead. I rather the weight of a trailer/cargo carrier be on the axle then the shock supports. Installation was simple and straightforward. Like others, I opted to disconnect the shock at the bottom mount than the top. It took me about 30 minutes per side, excluding tire removal and jacking up the vehicle. Suggestion... use a hydrolic jack to lift the axle a bit if you have a tough time getting the bolt connecting the shock to the mount. Do the same to reinsert the bolt when reassembling. The jury is still out on performance, however, I'm sure it will do fine based on other reviews. I attached some before and after pics. 90865

Overpriced.... A little slow in time to ship out from etrailer. The product does work as stated. Our 2008 Chrysler Town and Country with 20,000 miles blew both rear self adjusting shocks. We do not carry heavy loads or more than 3 people. Luckily we were still under warranty, otherwise it would have cost $300.00 per shock (parts only). In researching the shocks for the van I came across several articles on the Timbren Suspension Enhancement System. They look like what I needed to keep the shocks from going again. The price seemed high for two small rubber cylinders....but with the money back guarantee I gave it a shot. I installed them yesterday, the video was a little help, but not enough detail on how to remove and tighten the upper bolt on the shock absorber. The ride and handling of the van has improved greatly. No lean on turns and bumps are roll side to side. I recommend these for anyone with this van, even if you don't carry heavy loads, the ride improvement alone is worth the install, (easy for a novice to do). I would have given excellent if it weren't for the high cost. 21592

Also do one tire at a time (Safety) sorry no pictures. etrailer was quick to process and ship order. Great Business. Thanks etrailer Dennis O. 170343

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

I initially ordered the wrong part, # TTORTUN4L. after realizing that I needed part, "TORTUN4" I gave them a call and the change was made before shipping, and with no problems. Very professional staff and easy to deal with. The product arrived in a timely manner and as advertised. It took me about 15 minutes to install (without removing the tires). I just crawled under my 2007 Toyota Tacoma pre runner, removed only one U-Bolt , slid one end of the Timbren under the other U-Bolt and placed the U-Bolt I removed back in place over the other side of the timbren and tightened. Repeated on other side. Due to having a fiberglass camper top on the bed and custom built storage inside of the bed the timbrens just barely hit the top bracket. therefore, the ride changed slightly, but not as bad as I thought. The springs do help significantly with body roll when making sharp turns. Overall I am extremely pleased with them. Haven't had a chance to tow with them yet, but can tell by the stiffness that there will be no problem with sagging. Thanks for the great product a helpful staff. Mark 162116

Review from a similar Timbren Aeon Spring System in Vehicle Suspension

Very easy to install. I was able to get the old ones by prying them out with a screwdriver. I slipped the new ones in by spraying them with soapy water. I placed a 4x4 post underneath them as I lowered the jack. This seated them properly; make sure you don't skip this step or they will come out. Hooked up my 27' TT and what a difference. I didn't take measurements but I would say about a 3 inch difference. Not great pictures for comparison but I think you can see the difference. 345873
