Heavy trailers and bed loads can make the rear sag and the front rise. The Timbren Suspension Enhancement System adds up to 8,600 lbs of load-leveling support to keep your vehicle level when towing or hauling. The hollow rubber springs mount above the axle to share the weight with your factory suspension, improving stability, braking, and steering while keeping headlights aimed where they should be.
Each Aeon hollow rubber spring cushions bumps and rough terrain by flexing progressively as more weight is added. Under light loads, they allow normal suspension travel for a comfortable ride. As the load increases, the springs stiffen to absorb road shock and prevent bottoming out. This setup reduces wear on your stock suspension and gives a smoother, more controlled feel when the road gets uneven.
Each spring works independently to support its side of the vehicle. This design helps correct off-center loads and cuts down on body roll when cornering or swerving. Whether it’s crosswinds, uneven pavement, or a trailer tugging behind you, the truck stays more level and planted so you can steer with confidence.
No airlines, compressors, or manual adjustments needed. The custom-fit brackets bolt directly to each frame rail above the rear axle with included hardware—no drilling required. Once installed, the springs automatically engage only when needed, giving you support under load without changing how your truck rides when empty.

Now that its been a year Im very impressed with them. Theres no ride detriment without the 5th wheel attached and they do a great job of mitigating squat

Glad we had the right suspension upgrade to help with the squat Dennis! How is the ride when you are unloaded?

These are awesome! I tow a 37 Mobile Suites, which are built heavier than most, I put the Timbern on and it smoothed out the ride perfectly, best of all I still have my factory ride when unloaded, which you wont get with air springs.

Thanks for taking the time to share such a detailed review and all of the pictures! The unloaded ride is a concern we hear fairly often with SES upgrades, so your experience with the 1" gap and rough-road testing will be really helpful to others considering these for their F-250. We appreciate the kind words about Naomi and our team as well. Looking forward to your update once you get some miles on them with the Rockwood!
