Features to know about

Stay Level and Confident Under Heavy Load: 8,600-lb Rear Suspension Support

When the weight stacks up from a trailer or a full bed, this rear suspension enhancement keeps your ride level and controlled. The Timbren Rear Suspension Enhancement System adds up to 8,600-lb capacity support that works with your factory suspension to reduce sag and squat. With the extra help above the rear axle, steering stays responsive, braking stays even, and headlights keep their proper aim—no more dragging tail or nose-high stance when towing or hauling heavy.

Smooth Out the Rough Stuff: Hollow Rubber Springs That Absorb Shock

Bumpy roads and uneven terrain don’t have to beat you up. These hollow rubber springs sit above the axle to take the brunt of every bump and rough stretch. The elastic rubber design cushions light loads and progressively stiffens as more weight is added, so you get a smooth ride when empty and strong support when loaded. The result is less shock, less bounce, and less wear on your leaf springs.

Stay Steady in Crosswinds and Turns: Independent Spring Action

When wind, corners, or uneven loads threaten your balance, each side of the Timbren system reacts on its own to keep your vehicle planted. The independent action reduces body roll, helps correct off-center loads, and keeps trailers tracking straight even when gusts hit or a semi passes. You’ll feel the difference in how stable and predictable your setup feels on long stretches or tight curves.

Getting solid suspension support shouldn’t take all weekend. This kit includes two Aeon hollow rubber springs, custom-fit brackets, and hardware that bolt right in place of the factory bump stops—no drilling required. With just basic tools you can have them mounted and ready to go. Once installed, there are no air lines or adjustments to worry about—just load up and drive knowing your suspension is doing its job.

8,600-lb Capacity. These hollow rubber springs sit above the rear axle to help stabilize and level your vehicle. They also provide a more comfortable ride by absorbing road shock and improving roll stability. Easy to install and use.

by:

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.



by:

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.



by:

Order came fast and right. E-Trailer gets it the first time !!
Installed fit perfect



by:

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.



by:

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.



by:

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.



by:

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.



by:

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.

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.



by:

Great upgrade when pulling our 6500lb travel trailer. Helps with sag and control on the road on our Ram 1500. Change the stock shocks and if you choose, upgrade your stock springs, and you'll get the most out of your half ton.



by:

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.



by:

Easy install took about 20 minutes on my 2017 Ram 3500 SRW. Had about 1/2 inch clearance as recommended. Loaded up my 5th wheel (2350 hitch weight) and about 200 lbs of gear in the bed. Just got back from a 800 mile camping trip through mountains of TN. You can really feel the difference around those sharp corners and uneven surfaces. The truck felt firm and controlled not hard and jarring as some have mentioned. Going over those overpasses with the wonderfully smooth (Not) joists was greatly improved. The truck would squat and rebound again, with a firm controlled response. Driving without a load felt the same as before without them. I would highly recommend these! Ordering from etrailer continues to be my go to option!

Greatly helped the roll of the workhorse frame

Great addition to the rear end.

Its ok but not that differences, highly recommended for air bags instead these



by:

Timbren is a nice product but overpriced for what you get. They did give my motorhome a bit more sway support but made the ride more sharp, even on small cracks/bumps in the road. A sway bar would have been a much better way to go.



by:

I've had them installed for a year, still working great! Easy installation with no drilling needed. Simply bolt right in. Great product.

Great!

These “overloads” are such a great answer to suspension needs! They are made with high grade materials and the installation was a snap! I would buy them again many times over! Don’t mess with air bags, compressors, air lines and all that “stuff.” These are the deal!! Pictures of before and after. Simple way to add significant suspension payload quickly with little fuss.

  • Size of Bolt that Comes with Timbren Kit part # TWRW22
    The bolt size that comes with the Timbren kit part # TWRW22 is M10x60mm x 1.5. Basically just enough of the bolt comes through the assembly and frame to secure it with the nut on the truck frame.

  • SumoSprings For a 2005 Winnebago Voyage 35A on Workhorse W22 or W24 Chassis
    It appears your 2005 Winnebago Voyage 35A sits on Workhorse W22 or W24 chassis. These chassis will use the Front # SSF-280-47 and Rear # SSR-280-54-1 SumoSprings. I really do not like Timbren # TWRW22 being used as these springs are very stiff compared to the SumoSprings. This causes more shock to transfer through the suspension rather than being absorbed by it.

  • Recommended Suspension Enhancement for 2007 Winnebago on Workhorse Chassis
    Based on my research, it looks like your 2007 Winnebago Voyage 33V was built on the Workhorse W20 chassis with 4-wheel drive. I do recommend verifying this information with your paperwork for the RV, as it looks like there were a few different models of that Winnebago. For suspension enhancement, I recommend the Timbren Front Suspension Enhancement System # TWFRW22 and Rear Suspension Enhancement System # TWRW22. These are jounce-style springs like the ones you were looking at that will...

  • Timbren Suspension Enhancement For 2003 Winnebago Adventurer 38G
    The Timbren Front axle Suspension Enhancement System part # TWFRW22 is a fit for the 2003 Winnebago Adventurer 38G on the GM Workhorse chassis. I recommend to also add the rear suspension part # TWRW22. The Timbren springs are a great option to level out the motor home and help with body roll when turning corners. If your Winnebago is on a Ford chassis, you need part # TFFF53B for the front and part # TFRF53A for the rear. You may also consider adding a steering stabilizer part # RM-RBK22-RSSA...

  • Is Weight Capacity for Timbren Suspension Kit # TWRW22 for Both Springs or Per Spring
    The capacity of the Timbren Rear Suspension Enhancement System # TWRW22 that you referenced is 8,600 lbs for both sides together. You should note that these kits give you additional suspension support but they do not add to the capacity of the vehicle. They only allow you to carry your current capacity in a safer way.
