From highway driving, to heavy load applications, the Timbren Suspension Enhancement System will protect your current suspension, and will improve the performance of your vehicle whether it’s a pickup, suv, medium duty straight truck, or a full size class 8 truck.

The Timbren Suspension Load Booster is designed to provide stability, reduce swag, eliminate sway, and level the vehicle for an overall improved, "rubber cushion" ride - on or off the road. All while maintaining the current ride height.

One of the best product I have ever purchased. My 2004 Silverado had a snow package on it, I added the Timbren and it was a major improvement. I did front and the rear. It made plowing snow way better and I can haul tons of stuff without any sagging. Very happy with my purchase. The customer service couldn't have been better.

Great product! Excellent customer service! I have a lifted ½ ton truck that I carry approximately 1800 lbs in constantly and they were able to accommodate for the height difference! Definitely would recommend using their kits!!

I got them for my GMC 1500. I haul a heavy trailer. They work great. They will be going on all my trucks.
