SuperSprings are progressive in nature in that they work on an as-needed basis. The installed springs are under nominal tension even when the vehicle is unloaded.

This is for two reasons:
So that there is no rattle or noise from the installed SuperSprings and that the patented rollers will activate automatically.

As the vehicle with rear leaf springs comes under load the factory springs react as they are designed too. The center of the springs move vertically causing the overall leaves to flex and flatten out. This movement in the factory springs activates the SuperSpring through the rollers at the end of each leaf. Because the SuperSpring rollers are under tension, a movement in the factory spring causes them to move, seeking their new point of lease resistance. This simple roller principal allows the SuperSprings to activate and deactivate automatically, free of any manual adjustment.

  • Per the manufacturer: SuperSprings enhance load carrying capacity, handling and towing. Do not load any vehicle beyond the manufacturer's gross vehicle weight rating
  • Will not fit cab and chassis models
  • Will NOT work with aftermarket installed leaf springs. OEM only

SuperSprings International, Inc.

Founded in 1996, SuperSprings International, Inc. has developed a patented line of suspension products that solve many of the handing problems associated with loads carried by passenger vans, pickup trucks, minivans, and SUV's.

The first product developed was SuperSprings; self adjusting leaf suspension stabilizers which provide users extra loading and towing capacity and prevent rear-end sag without hardening the ride. Initially developed for the compact truck market the product range now includes SuperSprings applications up to and including class 5 (19,500 GVWR) work trucks as well as vans and motor homes.

Our SuperCoils line of enhanced, heavy duty coil springs was added to address the same sagging issues for trucks and vans with coil spring suspensions.

Our SuperKey line of torsion keys was added to provide customers with up to 2" of front end lift without changing the ride on their trucks and vans equipped with front torsion bar suspensions.

Our SuperSway-Stops were developed specifically for customers with airbags installed who wished to reduce their side-to-side body roll issues. A quick and simple bolt-on application, they allow the factory overload springs to better interact with the frame mounted snubbers as designed.

Our front SumoSprings were developed specifically to address snow plow, winch and heavy duty replacement bumper applications and permit a smooth engagement when both loaded and unloaded.

Our patented rear SumoSprings were developed as an "airless airbag" application for trucks and vans carrying a variety of loads. The microcellular foam material creates a leak proof and maintanance free option for customers. Our goal has always been to provide outstanding products coupled with exceptional customer service.
