When the trailer tongue or bed load starts to drag your rear end down, these hollow rubber springs step in to keep things level. With a 3,000-lb capacity, the Timbren Rear Suspension Enhancement System adds extra support only when you need it. The springs sit just above the axle to take over as weight increases, keeping your rig level so steering, traction, and braking stay consistent under load.
Hit a rough patch or bumpy back road and you’ll feel how the rubber construction makes a difference. Each hollow spring compresses to cushion impacts before they reach the cab. By soaking up road shock and preventing bottoming out, they help your suspension last longer and keep your ride smoother even when you’re hauling gear or pulling a trailer.
When curves or sudden gusts try to push you around, each Timbren spring works on its own to keep that side planted. This independent action cuts down on body roll and sway so your vehicle feels more stable through corners and uneven roads. It also helps reduce trailer sway by keeping movement from transferring back and forth between tow vehicle and trailer.
Adding rear support doesn’t have to be complicated. This kit bolts into place using vehicle-specific brackets and hardware with no drilling required. Once installed, the rubber springs hang about 1" above the axle so your factory suspension works normally when unloaded. As weight builds, the springs engage seamlessly to deliver the extra support right when it’s needed.

Ratings & Reviews
I've had these on our tow rig for a year now and I added buy them again today if I needed them.these have worked much better than airbags for our coil spring rear suspension to handle the tongue weight of our trailer. The SUV sits level when the trailer is on and it handles bumps and sway better than the airbags did providing much more comfort to us in the vehicle. Unloaded, we don't really notice they are there, unless, we have all the kids and some friends loaded up and you will fell them work when going over bumps.i do all my maintenance on the vehicle's and inspect these regularly and I cant see any wear so far even though we've gone on 6 trips with our trailer with about 5000 miles doing so.
I cant say these are the best for every truck or SUV, but for ours it is the best and I definitely would recommend to others.
2,000 miles in on a trip from the east coast to the Canadian Rockies these work great while loaded and towing. Close to zero bounce while towing, I love them. Unloaded, however, the ride in my 2026 Tundra has gone south. There is a noticeable, abrupt stop of the units hitting the axle when going over any kind of bump. When I get home and back to regular driving, I may just take them off, its that bad.
Well they are exactly what I thought it would be. Hard for me to say it's what I needed yet.
I installed them on a homemade trailer from a salvaged 2001 base model tacoma. Once I get finished building it out and have some weight in it I'll have a better idea. But from what I've seen so far on a couple test drives they should come into effect when needed.
For reference I building an Tacoma based trailer with an ARE Contractor topper with a Naturnest roof top tent on the very top. So to counter and sway these should be very helpful. At least I hope so. I'm not an engineer but I did stay at an Holliday Inn once.
The Timbren SES is a simple solution for rear squat when towing. When hitched to my 30' Airstream Globetrotter (8800 GVWR) with a tongue weight around 1200 lbs, my Silverado 2500HD had a bit more squat than is ideal. I shopped airbags but didn't want to spend ~$2K for the set up and didn't want the hassle of installation and forever chasing air leaks. The Timbren SES literally installs on the Silverado in about 15 minutes. So simple. No bags, no compressor, no wiring, no air lines, no leaks. And WAY less expensive to boot. Just returned form a 600+ mile trip and it towed flawlessly.
A very simple and straightforward installation once you get the oem bumper stops off (had a shop do that)
Timbren worked with me as I had a non OEM frame height (vehicle was lower than stock) to recommend the proper kit. Highly recommend contacting timbren if you are unsure of the proper kit to use. Ride is more stable. It does feel stiffer and less bouncy but am looking forward to seeing how it performs with my truck camper. Truck is a 1998 dodge ram 2500. Brake line over left side of axle needed to be secured to prevent damage.
The Timbren overload spring/bumper was east to install and did what it was supposed to do when I hitched up a camp trailer. These did not negatively affect the ride by any means and I don't have to worry about the troubles with air bags.
Stiffens and corrects kneel in rear end of 2023 Chevy Silverado 1500. You will notice a stiffening of the rear end suspension while unloaded, but it’s a fair trade off to prevent sagging and porpoising while towing. I found it easier to pull the rear wheels and work from the side than underneath the vehicle while installing.
The timbres bump stop is exactly the right height to meet the axel when the trailer is connected with all its weight onto the hitch. I have an Andersen weight distribution hitch and it levels out perfectly. The day picture is with the coach (Winn 2100bh) with factory equipment. The night picture is after the timbres are in place. Looks good.
It has been almost a year since I installed Timbren Suspension Enhancement Systems (DVF350 and DVR350R) on the front and rear of my 2003 Dodge RAM Van 3500. These bumpers replaced the OEM bump stops that were on my van. I like the Timbren bumpers much better than the OEM bump stops because they provide a progressively cushioned response for suspension compression when traveling over significant humps like speed bumps in a parking lot, or curb ramps into driveways. I did not like the abrupt stop the OEM bump stops provided when traveling over the same objects. I installed the Timbren rear bumpers first, and after a few months of use, I decided to add them to the front. In both cases, the front and rear Timbren bumpers were easy to install once the OEM bump stops were removed. Installation required reuse of the factory hardware. On my van, the Timbren bumpers are not always engaged. Under normal load and travel conditions the bumpers are relaxed and about 1/2” away from the suspension landing points. However, their presence is much appreciated and very noticeable when the van is carrying heavy loads or handling significant humps.
Absolutely Pleased with the TIMBRENS. They were easy to install, and took less than an hour to install both. I noticed a slight stiffness in the ride as the rear bounced over a bad roadway. Towing is great, with a nice level and smooth ride. I am glad that I did not order the heavier duty Timbrens, than what was recomended for my truck. I believe the ride would have been too stiff. If you look at the photos showing the timbrens, the truck is still lifted in the rear, so what you see is a big gap between the rubber, and the steal plate. When the truck is lowered, there's 1" of space as it should be. BTW, I have been purchasing from etrailer for years now, and I have to say that I have never had any issues with any orders. They are my go to folks for all of my vehicle suppension stuff and trailer stuff. You can't go wrong with buying from them.
Just got these on and haven’t been able to do a lot of testing yet, but it looks like they command their price. Huge difference in sag in the rear end of our Honda Pilot. As others have appeared to do in this review section before me, I started using a WDH with these and that looks to really be the winning combination with the Timbren SES. Our travel trailer is 3,500 lbs and it was squatting the pilot pretty well before. This timbren SES is a great addition. Can’t go wrong.
My F53 was like driving a waterbed down the road. With the Timbrens, it’s a different vehicle. Should have installed them years ago. Etrailer is my go to for anything trailer. FAST shipping and prompt responses to questions or concerns.
2022 F250 Super Duty. Super easy to install. I have about 3/4" gap between the spring and the plate. Time will tell how they impact the ride quality and how much sag they mitigate with my 5th wheel hooked up.
Timbren Spring Helpers were exactly what I needed on my Tundra plus a spacer kit since I have a 3” TRD lift. They were packaged neatly, with proper hardware, and excellent instructions! They absolutely do exactly what they are supposed to do! Truck rides much better and helps level out the load!
I'm suitably impressed with the difference i feel.
I have about 250 lbs. of static load with my topper and Decked cargo system. This put my install gap with no spacers just under the reccomended 1 inch minimum.Then add a couple hundred more pounds hauling music gear 100 shows a year, and the stop is resting on the axle.
I feel the absorption of the Timbren material is better than the flimsy stock bump stops. More cushion.
Where i really feel the difference is in the stabilty of excessive side sway when turning while loaded.
I have a gig coming up that will involve some unpaved mountain roads to get there so I think i will have a real goid idea of how these Timbren's will perform.
Instalation took me about an hour at 11 p.m.
The product it of the highest quality in design and build.
And Etrailer is a company that I would not hesitate to buy from in the future.
Thanks Dee Dee.
You rawk!!
They are just right, so easy to put on. thank you !
Fits perfect in my Tacoma 2015 rwd NOT prerunner excelent material.
They were very easy to install. I was disapointed that they were not a little longer. The ride is not as good unless there is a load in the bed. If the the spring tension/ deflection rate was different the ride could be made to be more consistant. A longer spring would keep the feel much better for the veried loads.
I bought a set like these for my previous Tacoma and liked them so much I bought another pair for my new Tacoma. These are great because they are so simple to put in and when the vehicle is not loaded you do not notice any difference in the ride. When loaded it keeps the truck from sagging and makes it more stable on the turns. Incredible product.
My Tacoma had a recall and I got a free undercoating. When I went to remove the OEM rubber bumpers and put on the Timbren rubber bumpers, I found a bug rust spot that had no undercoating. So glad I installed these.
They went on exactly as directed, everything lined up perfectly and looks like they will work well. Haven't put a load on them yet but I'm sure there won't be a problem.
So far I would recommend. If anything changes I'll let you know.
Exactly what I was looking for and what was advertised. Simple installation and total job was less than 20 minutes. Solid quality and effectively eliminated the sagging and swaying and without a load, I can't even tell they're on. It's made all the difference when hauling my trailerable sailboat and when hauling gravel. Would definitely recommend to others.
Hi:
I've installed the trem bre (TTORXR)overloads in every LT Truck I've owned, more then a dozen times. When needed they work super. Will be ordering another
later today. There A GOOD SEND for peace of mind & safety
Too soon to tell but it was a super easy install. After installation there was a 1-1.5 inch separation between the timbren and differential like the instructions call for and when fully loaded My truck bed saggs 2.5 inches ( I have measured this in the past) so therefore this will definitely will help my issue
Wow??????????It’s AMAZING the huge difference this suspension has added to my rear suspension it feels so great when I driving on the freeway it flows so cool I am real happy and grateful for this incredible product
