Hypercoils 3" I.D. x 14" Tall

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.

Hypercoils 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.

Hyperco is well-known for our high-performance suspension springs in the Motorsports world. Our springs have been on every winner of the Indianapolis 500 since 1965. The same technology we use on winning race cars, is also used for Hyperco’s coil-over springs for Off-Road and Powersports applications. Whether you’re riding through mud, sand, puddles, snow or rocks, Hyperco suspension springs offer your vehicle better total performance that lasts longer.

Benefits of Hyperco Springs in Powersports

  • More deflection = a smoother, more consistent ride with the ability to handle more weight
  • Less weight = an increased efficiency with movement and response time
  • Increased rate linearity = a controlled, more predictable and safer ride
  • More resistance to bowing = less friction and wear for an enhanced shock life
  • Maintains free length and installed height (springs won’t sag over time) = a consistent vehicle height and ground clearance
