8,000-lb Capacity hollow rubber springs sit above the rear axle to help stabilize and level your vehicle. Provides a comfortable ride by absorbing road shock and improving stability. Ideal for trucks with slide-in campers or an in-bed salt spreader.

Specs:
Whether you're hauling heavy loads in your bed or cargo area or you're towing a trailer, you will often see the rear of your vehicle sag while the front end rises. In these cases, the rear axle is handling not only the weight of the cargo, but also more of the vehicle's weight. 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 comes with custom-fit brackets that are 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, 1" 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 your vehicle level.
Each hollow rubber spring works independently to support the driver's side 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 your vehicle. 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.
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.

Ideal for trucks with slide-in campers or an in-bed salt spreader.2022 Ram 3500, 30 minute install time, great product. Hooked up camper without sway bars and only squat 3/4 inch, where before 4 to 5 inches. Recieved product in 3 days with etrailer staff sending me numerous emails. Great job to etrailer staff. Thanks
Shipped in their flimsy packaging which cannot handle the UPS truck. Box broke open, UPS taped it and all the hardware is missing. Called etrailer and said I needed hardware asap. Now three days later and nothing. I have a trip on Monday. Very disappointed.
Had a problem at post office with address label so they didn’t except the first delivery called and they re shipped immediately no questions asked,which was awesome! Second time they made it only to find they shipped the brackets only, once again called and shipped the other immediately, so customer service is great,which is rare these days! Would recommend ordering from them to anyone!
Didn't come close to needing the rubber discs that come in kit. Kind of a waste as these are somewhat expensive. What I used of kit seems to work fine.
The installed very easily and without incident. However, after the first outing (about 1000 mi on paved roads) the ride quality proved to terrible that I removed them. They solved the sway problem I had but rear suspension rebound was so harsh I was afraid the truck frame was likely to be damaged. It was like having no suspension at all in the rear.
Very good quality and took less than 30 minutes to install. I tow bumper pull RV's and a 5th wheel. Can't wait to tow 1 and see how it works.

Works great. I also have 1 on a 99 2500 Silverado. Thats why I purchased this one. You dont know you have it until you hook up a trailer or load something in the pickup. Then it just works. I will definitely continue to purchase one with each pickup I purchase.
Easy installation in about 40 minutes. On heavy truck with dump body and hoist the install has no gap between SES and axle. This is not effecting the empty ride and should definitely improve the stock suspension sag when loaded. Very happy!
Easy installation. Works great.
the product was very easy to install, but I was very dissatisfied with the ride of the truck after installing. The rubber distorted and there was almost metal contact with the bolt holding the spacers in place with the real axle housing. We have replaced your product with an air ride suspension which I am extremely happy with. I would not recommend this product to be used.
So I recently had two product purchases from etrailer, my Timbren load suspension upgrade and my truck bed camper frame mounted hold-downs, both to be installed on my 2016 3500 Ram. The installation and performance of both of these products went very well. I received great phone support from etrailer operators, as my buddy and I have in the past. It was my buddie Mikie who originally recommended your Company from numerous purchases he has made with you.
Easy to install. Took 20 minutes without air tools
For all intent they appear pretty good and they were very easy to install. However I haven’t had the chance to see how they work under load. All of the input from RVers my wife found on YouTube has been positive.
Arrived early, thank you.
Very knowledgeable and helpful with my purchase. Followed up to make sure everything was fine. Great experince.
It looks like the product I received was used. Not too excited about that.
