When you’re towing a trailer or hauling gear, rear-end sag can throw off your steering and braking. The Timbren Suspension Enhancement System adds up to 3,600 lbs of load-leveling support to help keep your vehicle level and stable. The hollow rubber springs sit above the rear axle to assist your factory suspension, reducing squat and improving overall handling when the weight’s on.
Bumpy roads and uneven terrain don’t have to beat you up. Timbren’s Aeon hollow rubber springs compress progressively—the more weight they take, the firmer they get. Light loads feel cushioned and smooth, while heavier loads stay firm and controlled. They absorb road shock and prevent bottoming out, helping your suspension last longer while keeping every drive comfortable and steady.
Each spring works independently to support its side of the vehicle. That means when crosswinds hit or you corner hard, body roll is reduced and handling feels more planted. This independent action also helps balance off-center loads, keeping both sides steady even if one is carrying more weight than the other.
Installing suspension support shouldn’t turn into a full weekend project. The Timbren system includes two hollow rubber springs, custom-fit brackets, and hardware that bolt directly onto the frame—no drilling required. With a straightforward design and no airlines or compressors to route, you can get reliable load support without extra adjustments or maintenance.

I was pleased that the Trimbren product kept my Canyon level with travel trailer. But even though I was payload legal and my Canyon diesel could handle the trailer from a suspension stand point I never felt comfortable towing. I knew I was close to the payload capacity and on certain road types a rhythmic bounce would occur forcing me to slow well below speed limits. It is true that you can not increase payload limits by adding air bags or Trimbrens they just help level the vehicle. I ended up trading the Canyon for a HD Ram 2500 diesel and changed my world!

Since purchasing the bump stops from E Trailer I have been hauling a 5000 lb. Travel trailer for about a year. I am very pleased with the ride of the truck under a load. The Tembren bump stops improved things significantly. Thanks E Trailer! Another purchase made from you and a very satisfied customer.

Prior to installing the Timbren kit, loading my golf cart caused the truck to squat some three to four inches. Now, the same load causes about a 1 inch lower stance. The loaded truck handles as if there was nothing in the bed.

Still think it is a great product...but without the bed load, the ride has proved to be a bit uncomfortable in such a light truck. I was on the fence about keeping them on so I removed them temporarily and realized how much of an impact it was on ride quality. They def help with a bed load or a trailering laod. The truck is fine trailering without them but with a 12-58 ton bed load, they certainly were a great help.

Timbrens are great Brandon! What are you hauling that requires additional support?
