SuperCoils are heavy duty, high-quality steel coil springs that replace your OE coil springs. Like other coil springs, SuperCoils have a linear/constant spring rate. While SumoSprings are used WITH your existing coil springs (or SuperCoils), SuperCoils REPLACE your factory coil springs. A very popular solution is to install SuperCoils and complement them with SumoSprings Solo instead of factory bump stops.
SuperCoils may or may not lift your truck slightly (an inch or two), depending on your make and model. The lift is a functional lift, to provide additional load support. Other SuperCoils are designed to maintain the stock ride height.
SuperCoils provide an easy and maintenance-free suspension upgrade. They can be installed in less than two hours and carry a limited lifetime warranty against manufacturer defect.
