(UPDATED May 21, 2013 with VIDEO) March 20, 2013 – At the Work Truck Show 2013, SuperSprings introduced new “fit-it-and-forget-it” suspension enhancements for the Ford F-550 and Ram 5500. Composed of microcellular urethane, SumoSprings increase load-carrying capacity, promise a smooth load engagement, reduce side-to-side body roll and improve ride. Unlike an airbag, they are completely maintenance-free and do not expand outward when compressed. SumoSprings have been tested in temperatures ranging from -25F to 200F. Typical installation takes an hour or less using standard tools.
Meantime, new Coil SumoSprings slide between the turns of front and rear coil springs to offer a progressive spring rate and provide extra support for the suspension when needed. A vehicle equipped with Coil SumoSprings will experience less side-to-side body roll, front-end dip and sagging without a compromised ride. The short, cylindrical Coil SumoSprings feature an H-shaped cross-section that helps hold them in place. The trapped air within the closed cells of the urethane provides up to 800 lb of support. The material is able to combine that support with a smooth engagement for maximum driver comfort.
