SumoSprings Suspension Kit - Rear

SumoSprings - The Airless Air Spring

The more you load the more they resist. SumoSprings reduce sag, bounce, sway, and bottoming out with a closed cell polyurethane foam airless air spring.

Manufactured from patented microcellular polyurethane foam, SumoSprings bellows act like a bunch of tiny air springs. As the closed cells within the SumoSprings are compressed, they get firmer and firmer just like an air spring. The combination of raw materials and engineering design produces a smooth ride and additional load support.

SumoSprings are designed to maximize the GVWR of the vehicle. Like other helper spring kits, they will not increase the GVWR or the carrying capacity of your truck, but SumoSprings will help maintain your truck’s level attitude, and enhance the ride and handling.

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 SUV's.

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.
