When you’re hauling a heavy load or towing, rear sag can throw off steering and braking. The Timbren Suspension Enhancement System adds up to 1,800 lbs of load-leveling capacity with hollow rubber springs that sit above the rear axle. As weight increases, the springs get more rigid to keep your vehicle level and stable under load. The result is better control, safer handling, and a level ride when the cargo or trailer gets heavy.
Uneven pavement and rough terrain can quickly wear out stock suspension. The rubber construction of the Timbren springs works like a built-in cushion, taking the brunt of bumps and jolts so your ride feels smoother. By absorbing most of the road shock before it reaches your factory suspension, these springs help extend suspension life and prevent bottoming out on rough roads or steep driveways.
When a curve or crosswind tries to push you around, each Timbren spring reacts on its own to keep your vehicle planted. That independent spring action helps reduce body roll during cornering and stabilizes handling when carrying off-center loads. You’ll feel more in control when changing lanes, taking curves, or towing through gusty stretches of highway.
Adding real load support doesn’t have to be complicated. The Timbren kit includes two Aeon hollow rubber springs, custom-fit brackets, and hardware for a straightforward install that bolts directly onto the frame—no drilling required. Once mounted, the system automatically adjusts as weight changes so there’s nothing to air up, tune, or maintain—just consistent support every time you load up.
Timbren springs will not increase your vehicle's weight-carrying capacity. Do not exceed the manufacturer's recommended weight limit.

Hi, everybody. Andy here with etrailer.com. And today, we're gonna take a look at this Timbren rear axle suspension enhancement system. Now, these are custom fit parts that are designed to fit the 2018 and newer Chevrolet Equinox. To confirm that these work for your vehicle, take advantage of our vehicle fit guide here et etrailer.com and input the year, make and model of your vehicle, and our fit guide will let you know if these will work for you or if we have something comparable that will work for you. These hollow rubber springs with an 1,800 pound capacity sit above your rear axle to help stabilize and level your vehicle.
They're going to improve your suspension, your handling, and safety. And these springs also provide additional support as needed so you always have a smooth, comfortable ride, allowing your leaf spring ample movement while cushioning light loads. They're going to ride just as smoothly when you're not hauling a load and they become more rigid as more weight is added for great performance when you're hauling a heavy load, increasing stability and reducing vehicle sag. They work independently adjusting side to side, helping compensate for off-center loads and reducing body roll when swerving and turning corners. Now, these springs also act as shock absorbers, taking the brunt of bumps and rough roads, extending the life of your vehicle's suspension.
So, this kit includes everything that you see here on the table before me. As you can see, I have these springs loosely installed on these brackets. But you are going to get two Aeon hollow rubber springs, and then the vehicle specific brackets, and the hardware for a simple installation. The good news is there is no drilling required. Then you're going to get an instruction sheet here to let you know what you have and step by step instructions to help you along with the installation process.
Now, again, the capacity is 1,800 pounds and it is important to note that these Timbren springs will not increase your vehicle's weight carrying capacity. So, you do not want to exceed your manufacturer's recommended weight limit and these do have a lifetime warranty. Well, that's gonna conclude our look today. I do hope that it was helpful for you. Again, my name is Andy.
Thank you for joining me..

Added these to my F250 Super Duty. I carry a golf cart on a Diamond back bed cover. Can be a little top heavy. Perfect addition to my suspension- greatly reduced the sway.
Easy to install using basic hand tools, and stopped the "sag" when I hook up my Casita travel trailer
Helps prevent about 1/2" of sag with my 175lb-tongue weight trailer and easy to install.
Great product. The ride and body roll at the rear axle are notceably improved (1989 Ford E350 Class C RV , 27 ft). I give it 4 stars because the installation was slightly complicated due to the rear brake lines needing to be slightly bent to provide clearance for the U bolts supplied in the kit. Great product and wish it came in a 5000 lb version.
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.
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.
Order came fast and right. E-Trailer gets it the first time !!
Installed fit perfect
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.
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.
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.
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.
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!
Great!
easy enough to install, however, I think I should have installed the air bags ones. reasoning. these work great if you haven't already bent something and now need to support the suspension. these work best I think to stop from bending things in the first place.
They work well does what we need it to do makes the car handle the load better
