Coil SumoSprings® improve the load leveling ability of original equipment front and rear coil springs. Manufactured from micro-cellular urethane, the material’s progressive spring rate with superior damping properties creates a cushion effect, enhancing capacity and ride comfort. They install by simply being slid between the turns of the coil spring. Every SumoSpring is handmade with care, making each one unique with its own natural characteristics, such as slight color variations and surface bubbles—proof of the craftsmanship that goes into every piece.
