SuperSprings SSA38 Details

SuperSpring Helper Springs

SuperSprings are patented self-adjusting suspension stabilizers engineered for vehicle with leaf spring rear suspension systems. SuperSprings by design provide users extra load capacity and additional vehicle handling and control, both without significantly hardening the ride.

SuperSprings simply install right over a vehicle’s rear leaf springs. They work in parallel with a vehicle’s existing suspension system and “kick-in” as needed. The increase in load carrying capacity delivered by installing SuperSpring helper springs helps eliminate vehicle rear-end sag and improves towing capabilities.

SuperSprings unique anti-sway feature reduces body roll providing enhanced driver control which can make the difference when entering a sharp turn or during an emergency panic over-correction situation. This is accomplished by SuperSprings patented tapered spring blade and rolling shackles. Feel the SuperSprings difference, whether hauling a heavy load, towing or just want the handling benefits that come with a more stable, secure and controllable ride.

each kit Includes a pair of SuperSprings. One kit does both sides of the vehicle.

SuperSprings

SuperSprings International was founded in 1996 and has developed a patented line of self-adjusting suspension stabilizers that solve many of the handling and suspension problems associated with loads carried by passenger vans, pickup trucks, minivans, and SUVs.

SuperSprings Internationals products give users extra loading and towing capacity and prevent rear-end sag without hardening the ride on vehicles having leaf spring rear suspension systems.

SuperSprings was developed for the American market with production initially established in California to serve the market on the West Coast. Marketing efforts have continued to expand and SuperSprings Helper Springs and SuperSway sway control are now distributed through a national dealer and distributor network throughout North America.

Product applications for SuperSprings have evolved from being solely for pickup trucks to a broad cross section of vehicles including SUVs, 15 passenger vans, minivans, and RVs including Class C motor homes and campers. SuperSprings have also been accepted by large-scale manufacturers in the van conversion business.
