When you’re towing a big trailer or hauling a camper that makes the rear sag, this system steps in with solid backup. The Timbren Suspension Enhancement System uses hollow rubber springs rated at 8,000 lbs to help keep your truck level and stable under load. The springs sit above the rear axle and work with your factory suspension to reduce squat so steering, braking, and headlight aim stay right where they should.

Heavy loads don’t have to mean a rough ride. These Aeon hollow rubber springs compress progressively—the more weight you add, the stiffer they get. Under light loads, they leave about an inch of clearance to let your stock suspension move freely. When conditions get bumpy, the rubber design cushions impacts and prevents bottoming out to give a smoother ride and help protect your suspension from wear.

Each Timbren spring works on its own side of the vehicle. That independent action keeps the truck balanced when you’re hauling off-center loads or making sharp turns. It helps cut down on body roll and limits trailer sway so your setup feels planted when a gust of wind hits or when you’re running through tight corners with a heavy trailer behind you.
Installing extra support shouldn’t take a full weekend or require compressors and gauges. This kit replaces your factory bump stops with custom-fit brackets and rubber springs that bolt to each frame rail—no drilling needed. Once installed, there’s nothing to maintain or adjust. The durable rubber construction resists leaks and keeps working trip after trip, backed by Timbren’s limited lifetime warranty.

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.
