SuperSprings are patented self-adjusting suspension stabilizers engineered for vehicles with a leaf spring rear suspension. SuperSprings provide users extra load capacity and better vehicle handling and control, without significantly hardening the ride.

Timbren SES (suspension enhancement system) Kits are easy to install, and require no maintenance. Made of rubber, the timbren bump stop is mounted between the truck chassis and the axle. Timbrens work with the existing suspension to eliminate sagging leaf springs and to protect it from suspension overload, bottoming out, and vehicle body sway.
