Details
Hyperco Coil-Over Suspension SpringsCoil-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.
2.25-inch ID A-Series Coil-Over SpringsBasic Specifications
- Free length range: 4” to 9”
- Spring rates: 150 lbs/in to 3800 lbs/in
- Material: High tensile chrome silicone
- Finish: Hyperco dark blue powder coat
- Spring Design(s): Optimum Body Diameter (OBD)
Note: Some 4″ and 5″ 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.
Spring Design ConceptsHypercoils are available in two different spring design concepts:
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.
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.
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
About HypercoBetter Performance That Lasts Longer
Hyperco is a supplier of precision engineered, high-performance suspension springs and related components supporting the Motorsports, Street Performance and Off-Road/Powersports markets. Our stock and custom suspension products improve the total performance, aesthetics and durability of your ride!
A Heritage of Winning
The racing suspension springs, now known as Hypercoils, were pioneered by Jim Fielder in the early 1960s. He was instrumental in developing the spring designs and their dominance in the motor racing industry. The spring designs and technology that originated from Fielder have evolved into what is today known as the Hyperco brand.
In 1996, Hyperco joined MW Industries Inc. to become one of the top spring and specialty fastener manufacturers in the nation. Today, Hyperco products are engineered and manufactured at our sister locations of Matthew Warren Spring in Logansport, IN and Pontotoc Spring in Pontotoc, MS.
Our high-performance suspension spring product line has grown and evolved over the years. Hyperco is still proudly known as the racing spring company. Now, we use that same winning technology from Motorsports, in our suspension springs for Street Performance, Road Cars, Off-Road and Powersports markets.
Hyperco springs are proudly designed and manufactured in the U.S.A. - Specifications
