Coil-Over Springs are high-performance, aftermarket suspension springs primarily used in Motorsports and Motor Racing. Hyperco’s coil-over springs, also known as Hypercoils™, offer a wide range of free lengths and rates which provide the suspension designer latitude in creating a motion ratio for the suspension system that will permit an optimized damper or spring assembly to control a wide range of wheel travel.
Hyperco’s Coil-Over Suspension Springs are made of a high tensile chrome silicone steel alloy and comes with a Hyperco dark blue powder coat finish.
Hyperco Coil-Over Springs are made in the USA.
