Heavy loads and trailers can make the rear of your vehicle sag and the front rise, throwing off traction and steering. The Timbren Suspension Enhancement System – Rear Axle adds up to 12,000 lbs of load-leveling capacity to keep your ride level and stable. Its hollow rubber springs sit above the rear axle to share the weight with your factory suspension, helping maintain proper stance and control when towing or hauling.
Bumpy pavement or uneven job sites can beat up your suspension. These hollow rubber springs act as shock absorbers, cushioning your truck from impacts that would otherwise transfer through the chassis. The progressive spring design collapses smoothly under light loads for comfort, then stiffens up as weight increases for stability. You get a smoother ride loaded or empty while extending the life of your stock suspension.
When corners or crosswinds push one side of your vehicle down, each Timbren spring reacts independently to keep things level. That means less body roll when you swerve or turn sharply and better control when hauling off-center loads. Because each side engages only when needed, you stay balanced without extra stiffness during normal driving.
There’s no need for compressors, hoses, or air pressure checks here. The Timbren system bolts directly onto the frame with custom-fit brackets and hardware—no drilling required. Once installed, it automatically provides extra support as load increases, so you can haul heavy gear or tow without having to make manual adjustments before every trip.
Timbren springs will not increase your vehicle's weight-carrying capacity. Do not exceed the manufacturer's recommended weight limit.

After a year the Timbren suspension product has been performing well - very satisfied. What I was not satified with was eTrailers response to my complaint of their service before and after my purchase. I still havent bought from them since.
