When the rear end starts to sag under the weight of a trailer or a loaded bed, this system keeps things level and stable. The Timbren Rear Suspension Enhancement System adds up to 12,000 lbs of rear axle support using hollow rubber springs that mount above the axle. As weight increases, the progressive design stiffens to counter squat and maintain proper ride height. Steering, braking, and traction stay consistent so your truck feels balanced and controlled even with serious weight behind it.
Bumps, ruts, and potholes are easier on your truck with these Aeon hollow rubber springs taking the hit. They compress gradually to absorb road shock and cushion each impact, protecting your suspension and cutting down on jarring movement. The springs help prevent bottoming out so you can travel over uneven roads with less bounce and less wear on your factory components.
Each side of the system works on its own to handle uneven loads or quick turns. When cargo sits off-center or you swerve to avoid something, the independent spring action keeps both sides steady to reduce body roll. The result is better balance through curves, less sway from crosswinds or passing vehicles, and a more planted feel when towing or hauling.
There’s no need for compressors or air hoses here. The kit includes two Aeon hollow rubber springs with vehicle-specific brackets and hardware that bolt onto the frame in place of factory bump stops. No drilling is required, and once installed the system automatically adapts to load without any manual adjustments. It’s a simple, durable upgrade built for hauling heavy loads day after day without maintenance or leaks.

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.
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!!
It's in it's working. I have no reason to complain.
Install was not bad, it took me about 1.5 hours to get them on just because I was trying to get the bolt to stay on my socket. I placed a nut inside the socket so it would reach the threads, after that it was easy. First drive felt solid definitely excited to see how they do loaded or towing. will check back when I do.
The product works exactly as described. The biggest benefit is the experience provided by etrailer.
Very fast shipping, had product in 2 days! Very easy to install. Hardest part was lifting the RV.
I just completed installation today. Directions could have been a little clearer but once I looked at it no problem.
Test drove about 3 miles and turned back one thing I noticed right away was ride was smoother.
My only concern is that the rubber springs don't line up in the center of the axial.
Package was damaged and the nuts and bolts where missing.
Called etrailer and they gave me a credit.
So got my own hardware and installed the product, it was easy to install except I had to raise the Rv frame by 8 inches in order to install it,good thing I have a 20t air jack .
We have not driven the Rv at this point, in a few days we will know more
I have a 2022 E450 Sunseeker 2850.
Timbren are the way to go. Progressive unlike sumo.
I emailed the folks at Timbren and they suggested the heavier duty ones. 12,500 lbs
I needed a 1” spacer. My buddy gave me his that we ended up not using on his 3/4 dodge short bed.
My goal was to have these barely touching when unloaded.
On pick ups you want that 1” space however, motorhomes are heavy and I wanted them to work all the time.
My goal was correct. The ride is fantastic. It takes 90% of the hard jolts away.
I believe these will make everything last in my motorhome longer. Things don’t rattle like a normal suspension.
Not a hard install. It took me a hour. Longer to get out the tools than to get it done.
Just finished installing Timbren's in the rear of my Ford E-450 motorhome. The installation was very easy. The hardest part was lifting up the motorhome so the rear tires were off the ground. I always install Timbren's on all my pickup trucks, and have always been extremely happy with them, so when I bought a motorhome, that was one of the first things I did. Because my motorhome came from the manufacturer with helper springs which increased the height or clearance, the Timbren's were not in constant contact, so I purchased and install a 1" spacer (part number A25723-90AH00). Now the Timbren's are in constant contact and will maintain the correct height and not sag under load. I love Timbrens!
