Coil SumoSprings(R) improve the load leveling ability of original equipment front and rear coil springs. Manufactured from micro-cellular urethane, the material's progressive spring rate creates a cushion effect, enhancing capacity and ride comfort. They install by simply being slid between the turns of the coil spring.
