SuperSprings' Coil SumoSprings slide between the turns of front and rear coil springs. Since their proprietary microcellular urethane material offers a progressive spring rate, they provide extra support for the suspension only 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 lbs of support. It can combine support with a smooth engagement for maximum driver comfort.
