Off-Road Coil-Over Springs
Coil-Over Springs are high-performance, aftermarket suspension springs often used for motorsports, racing, and off-road applications. 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 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 and side-loading
- Designed to fit all standard hardware
- Maintain free length and rate throughout a near-infinite operational life

Products
BASIC SPECIFICATIONS
- Free length range: 4” to 16”
- Spring rates: 85#/in to 1300#/in
- Material: High tensile chrome silicone
- Finish: Hyperco dark blue powder coat
- Spring Design(s): Optimum Body Diameter (OBD), Ultra High Travel (UHT), Dual Rate UHT
Note: Some 4″ and 6″ free lengths use a more traditional spring design as there are not enough active coils to allow an OBD design.
APPLICATIONS
- Motorsports: Circle Track and Sports Car Racing*
- Street Performance: Lighter weight sports cars where handling is important
- Off-Road: Motorcycles, Quads, Dune Buggies, etc.
