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.

Specs:
Whether you're hauling heavy loads in the cargo area or by pulling a trailer, you will often see the rear sag while the front end rises. In these cases, the rear axle is handling not only the weight of the cargo, but more of the truck's weight, as well. Because less weight is on the front axle, the front tires are making less contact with the road. Overall handling - traction, steering, and braking - is negatively affected. But the resistance from Timbren's Suspension Enhancement System works with your factory suspension to keep your vehicle level and improve your driving experience.
The Timbren system has a custom-fit bracket that will be bolted onto each frame rail above the rear axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down to where the bottom of the spring sits, one inch above the axle. The inch of clearance allows the existing factory suspension to operate normally under light loads and standard terrain, ensuring the smooth, comfortable ride that you are used to.
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 increases resistance, stiffening the suspension and keeping the truck level.
Each hollow rubber spring works independently to support the driver's or passenger's side of your 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 you are hauling off-center loads.
Because the vehicle handles better with the springs, less turbulence will be passed along to the trailer, and this helps to keep the trailer in line. Your driving comfort is further enhanced if the trailer does begin to sway (from a gust of wind or a passing semi), because the movement from the trailer is not transferred to the truck. This also works to make the sway subside more quickly.
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 because 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 - there are no air hoses to run, no compressors or gauges to hook up, and no manual adjustments to make. The rubber construction makes Timbren's springs more elastic than similar products constructed of microcellular urethane. And more elasticity allows for a more comfortable ride because the rubber has more travel.

Super easy to install on Ram 3500. Didn't have to jack up truck. Assembled is 6.5" on Ram 3500, I had 7" to play with so plenty of room. Haven't added a load yet as 5th wheel is on order. Looking forward to it. 609612
Walt - 03/03/2020the timbren tdr3500ca were a very easy install on my 2018 ram drw 4x4. The included spacers were needed and left about 1/2 inch clearance. empty ride is same. Will load arctic fox 990 soon and expect great results. I elected not to reinstall my air bags, when trading trucks. I also have upper stable loads and will not miss the air bags. ordering was easy and free shipping was fast. 612456

Timbren is expensive but have proven their worth so far. I have added another one of their products to my rig more improving its handling. I have run air bags in the past and these cushions far outperform that I will never go back. No maintenance and no hassle since I installed them. The were a slight challenge installing due to close tolerances and needed a medium well socket. My great friends at E-Trailer have also proven to be EXCELLENT, USA representatives that I continue to deal with and send many more customers their way. 260123
Bolt on quick fix to sagging springs truck rides a little rougher when empty but i used the spacers they are almost always touching when loaded they are amazing i pull campers for a living. I have around 180,000 miles since install so there working great for me no air lines to pinch or rub a hole in always hold the load up where i want it 454505
I recently had an air bag fail on my truck while loaded with our Lance 855 on the truck and pulling a small utv trailer. The shop that helped me had a set of Timbren bump stops. We modified my air bag mount to gain a little more height, installed bump stop and was on my way. My rig actually rode better than it did with the air bags, so I ordered these heavier duty Timbrens and installed them. Quick and easy, and after install I loaded the camper on my truck and it only settled 1". Perfect ! I can already tell these are going to be great. Thanks again to etrailer for fast shipping and great price ! 175160
Received my Timbrens very quickly, very well packaged. Installed them is less than 30 minutes. Have yet to hook my rv to the truck, but can see these are going to be really helpful. About 1" to my axle where my OEM bump stops were a good 7" As always etrailer rocks!! Look forward to dealing with these folks when the need arises again. 484817
Michael - 03/14/2019 Michael - 03/19/2019I tow 20k and these really work. They significantly reduce body roll and bottoming out. P.S. and they’re easy to install 854067
I made my own custom spacer so that when the truck bed is empty there is a 1/2 inch gap between the axle and bump stop so I would get the maximum benefit of these and not impact my empty ride quality. I tow a bumper pull 39 foot Toy Hauler and these work fantastic. Some of the best money I ever spent. 850326
This is the second set of these I have purchased from e trailer first one on my 3/4 ton dodge and these are for my 1 ton. They are a must have for towing 801407

Perfect 779668
Just installed these timbrens on my 2010 ram 3500 dually. Took about 30 minutes, really simple. Im hauling a lance 1172 and tow a bass boat occasionally. I decided to give these a try to help with rear sag and ride. I gained 1.5" after install. I will update after my next trip and i see how they perform. 763156
Little disappointed with the build on these for the price. Nasty weld spatter, poor paint/coating application, and the threads needed a tap run through them to clear the included bolts. 749055
When I called they were very knowledgeable about the products and made sure I ordered what was going to work on my truck. 736733
Very easy to install; had them on my Dodge 3500 in about 15 minutes. This is the second vehicle I have used these on; a great product for sure. 718427
Product was what I ordered. Shipping was awesome and customer service was awesome. I will install and take pictures today and write a review on how they perform. 695638
Easy install, perfect fit on my 2019 Ram 3500. 682886
Shipping was exactly as quoted on time. Fitment of product was easy and fast about 30 minutes including time to get tools out. I choose these over air bags,,, I have air bags on another truck and they are alot more complicated to install along with leaks. I just got them on so as to how they perform has not been established yet. If they do what they re designed to do I will be happy. 679135
Very easy to order, arrived within 3 business days Installed in less than 30 minutes. Took care of the slight sag I had when towing a 5 the wheel Would buy again 668259
David - 07/10/2020These allow my truck to sit level with my 17k lbs 5th wheel attached. Smooth ride and no squat.... Who needs airbags with this product? 664799
Evan - 07/01/2020Shipping was very prompt. Install was easy. Haven’t had a a heavy load on yet so I can’t speak to function. 640984
Installed on my 2007 Ram 3500 because I wanted basic leveling & stability under the load of my 5th wheel. I didn't want a complicated air bag system. Summer trips in the mountains of MT & the Pacific NW. 3 months of snowbirding throughout southern AZ this winter. Very satisfied, so I just swapped them onto my new 2018 Ram 3500. I didn't let them go with my trade-in. Just what I need, no effect when empty - engaged when I need them. 628560
Ordered and arrived as scheduled. No i ssues. 619492
