Coil SumoSprings, made from the same micro-cellular urethane used in SumoSprings and Trailer SumoSprings, improve the load leveling ability of OE front and rear coil springs, increasing capacity by 15-30%. Coil SumoSprings are installed simply by sliding them between the turns of the unloaded coil spring. The material's progressive spring rate creates a cushion that enhances capacity and ride comfort.
Coil SumoSprings increase driver control by reducing sway and providing tighter handling, which means longer life for your tires and brake pads. If you are adding new weight to your vehicle or your coil springs are getting worn out, Coil SumoSprings can give you the boost you need.
Note: The last three digits of the Coil SumoSprings part number indicate the height of the inner wall. For example, CSS-1125 has an inner wall height of 1.25 inches.
Coil SumoSprings carry a limited lifetime warranty against manufacturer defect.
