When the weight of a camper or trailer drops the back end of your truck, it throws off steering, braking, and headlight aim. The Timbren Rear Suspension Enhancement System adds up to 8,600 lbs of support to keep things level and steady. The hollow rubber springs mount above the axle and progressively stiffen as weight increases, reducing sag and helping your truck stay balanced when hauling heavy loads or towing.
Bumpy roads and uneven surfaces can make a loaded truck feel harsh. Each Aeon hollow rubber spring absorbs road shock and cushions impacts, giving you a smoother ride even with gear or a trailer on board. The springs take the hit before it reaches your frame, limiting bottoming out and cutting down on wear to your factory suspension.
When a gust of wind hits or you take a corner with weight on board, these rubber springs work independently to keep each side stable. That independent action helps reduce body roll, sway, and bounce so your vehicle stays controlled through curves or when hauling off-center loads. You’ll notice better steering feel and a calmer ride when towing down the highway or backing into a campsite.
You don’t need compressors or airlines to get reliable support. The Timbren system bolts directly to the frame using vehicle-specific brackets and hardware—no drilling required. Once installed, it automatically engages under load and disengages when empty, so you can enjoy normal ride comfort without adjusting air pressure or making manual changes.

Only had the use of the Timbrens for 6 months as I traded the truck in for a new one. The Timbrens were great while I used them. The only regret is that the new truck wont accept the Timbrens I had on the previous truck New and different frame.

I have had zero problems with the Timbrens on my truck. I have pulled our camper and several tag along trailers hauling equipment and parts. They do exactly what they are supposed to. Saves on sag by over an inch. No complaints here.
