When the weight piles on, the Timbren Rear Suspension Enhancement System keeps your ride level and steady. With a 6,000-lb capacity, these hollow rubber springs sit above the rear axle to help stabilize and level your vehicle when towing or hauling heavy gear. They work with your factory suspension to reduce sag and keep steering, traction, and braking in check so your truck feels planted and controlled even with serious weight on board.

Rough pavement, potholes, or washboard roads can beat up your suspension. Timbren’s rubber springs act as shock absorbers, taking the brunt of bumps and jolts so your ride stays smoother and your factory components last longer. The elastic rubber construction cushions light loads while still firming up as more weight is added, keeping comfort and stability in balance no matter what you’re carrying.

Sharp turns or uneven loads can make one side of your truck dip or sway. Each Timbren spring works independently to support its side of the vehicle, cutting down body roll and keeping things level when you swerve, corner, or haul off-center loads. The improved stability also helps reduce trailer sway by keeping movement from transferring between truck and trailer.


Adding load support shouldn’t mean tearing into your suspension. This kit includes 2 Aeon hollow rubber springs, custom brackets, and all required hardware for a straightforward install that replaces the factory bump stops—no drilling needed. Just bolt them onto the frame rails above the rear axle and you’re ready to roll with dependable support for towing or hauling heavy loads.

I only install them when I tow or haul a heavy load. They limit my suspension travel in the rear and give me a stiffer ride with no load. They work great with a heavy load present.

The Timbren suspension still working great. Although not intentional, a couple of months ago, I found myself in a situation where I had to pull a trailer and load that was about 9k lbs. or about 1500 overweight. I was able to pull it just fine and its all thanks to the Timbren suspension upgrade. If it had just been stock, I wouldnt have been able to do it.
