Coil-Over Springs
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.

Key Benefits of Hypercoils OBD/UHT Coil-Over Springs
- More usable deflection
- Less weight than standard suspension springs
- 2% rate linearity tolerance from 20% to 60% of deflection
- 4% rate linearity tolerance from 61% to 80% of deflection
- More resistant to bowing than competitor’s springs
- Designed to fit all standard hardware
- Maintain free length and rate throughout a near-infinite operational life
Hypercoils or Coil-Over Suspension Springs Come in Two Design Styles
-
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 by adjusting the spring’s body diameter.
-
Ultra High Travel (UHT)
Our Ultra High Travel springs are designed specifically for light rate / high travel coil-over applications, such as dirt and pavement racing. The UHT design meets the requirements of soft spring and big bar set-ups, and remains consistent in free length and installed height. The Ultra High Travel design features a larger “body bulge” over Hyperco’s standard OBD design, which allows for additional deflection, rate linearity, and resistance to bowing.
