A History of Unrivaled Success

Hyperco is a supplier of high performance suspension components for all levels of the motor racing industry. In 1996, Hyperco joined with MW Industries Inc. to become one of the top spring and specialty fastener manufacturers in the nation.

The Hyperco product line includes suspension coils (Hypercoils), Hydraulic load centering Spring Perches and Composite Leaf Springs. Hyperco specializes in the development and optimization of these products for the motor racing industry. Hyperco components are utilized by championship winning teams world wide- NASCAR Nextel Cup, Formula One, Indy Racing League, SCCA, NASCAR Busch series, NASCAR Craftsman Truck Series, Grass Roots Oval Track, Endurance Sports Cars, Off Road, Motorcycles “Hyperco components are a part of winning from Late Models to Nextel Cup”…Formula Ford to Formula One, (Hypercoils have been utilized by every Indianapolis 500 winner since 1965).

Optimum Body Diameter

Optimum Body Diameter (OBD) Hypercoils feature a unique design concept that adjusts the body diameter of the spring relative to the end coils. The OBD design enables Hyperco to take full advantage of its ultra-high tensile material by optimizing the applied stress through adjusting the spring’s body diameter.

The results are in and they are simply incredible:

  • More Deflection
  • Less Weight
  • Increased Rate Linearity
  • More Resistance to Bowing
  • Fits All Standard Hardware
  • Maintains Free Length


The life of a suspension coil is directly related to the design and materials used. Hypercoils are designed to be as light as possible with maximum deflection and at the same time endure the stresses of the extreme conditions common to motor racing. Because raw materials are ordered in mill-runs and not ordered from a mill’s regular inventory we are not constrained to designing from stock wire sizes. Having a larger range of wire sizes available allows our engineers to be design specific for each application. Hypercoils are designed and manufactured to retain their rate and free length for several seasons. A properly designed and manufactured spring will not lose free length under normal racing applications.

Labeling & Packaging

All Hypercoils are powder-coated a navy blue, the mean rate is etched into the end coil and they are packaged in reusable tubes for convenience and easy identification.


The material used in producing Hypercoils undergoes two separate magnaflux inspections. Once before manufacture and again after coiling. These inspections insure the wire is free from surface imperfections which, if gone undetected could lead to spring failure.


To properly test a spring to determine rate, the spring must be deflected with both ends remaining parallel. Portable rate checkers commonly available are not reliable. At Hyperco we have invested heavily in computerized scale test equipment to insure accuracy and consistency. Our scale has the capability to rate test a spring through it’s entire deflection in .100″ increments and print this data in both tabular and graph form.


Hypercoils are manufactured from the highest quality chrome silicone steel and high tensile chrome silicone steel available in the world.


Hypercoils are manufactured on state of the art equipment using the latest technology by craftsmen who take great pride in producing what we feel are the best springs available anywhere in the world. The manufacturing facility has the capability to produce almost any size or design of spring either cold-wound or hot-wound coils.
