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.

If your Ford F450, F550 Super Duty leans on turns and curves, drifts on the highway, bottoms out, or provides a general bumpy ride when loaded, a Timbren Suspension Kit is the solution for your suspension problem.

The Timbren Kits we offer are extremely simple to install, require no maintenance, and come with a lifetime of use backed by warranty. The award winning "over load" systems are made of Rubber Aeon Springs and designed to provide maximum performance for stock suspensions.

  • 12,000 lbs. Level Load Capacity
  • Reduces sag and sway
  • Eliminate vehicle from bottoming out
  • Perfect for handling heavy cargo loads
  • Ride quality unaffected when not loaded
  • Sold as Pair (left and right)
