Hyperco 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.
Options: ID: 2.25" Length: 9"
These springs have a 2.25 inch top and bottom coil to fit 2.25 inch spring perches.

Optimum Body Diameter (OBD)
Optimum Body Diameter is the standard spring design for Hyperco coil-over springs. Featuring a unique design concept that adjusts the body diameter of the spring relative to the end coils, an OBD spring enables Hyperco to take full advantage of our ultra-high tensile spring materials by optimizing the applied stress through adjusting the spring’s body diameter.
Key Benefits of Hypercoils OBD Coil-Over Springs
