Hyperco Sports car Coil OVer Springs

Hyperco suspension coil springs have been “a part of winning” for the Motorsports industry since 1965! For more than 50 years, every Indianapolis 500 winner has won driving with Hyperco suspension springs. Born and raised in the Motorsports world, Hyperco supplies race teams and chassis manufacturers around the world with a wide range of precision suspension springs and components. While some of our product lines tend to take top billing, we don’t believe in manufacturing second-tier products. We develop and produce custom springs, designed for better total performance that lasts longer. Today, Hyperco suspension springs encompass all areas of competitive motor racing as well as Off-Road racing and Street Performance applications.

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

  • Material: High tensile chrome silicone

  • Finish: Hyperco dark blue powder coat

Technical Info “Rate Overlap”: ‘Rate Overlap’ occurs when the manufacturer’s manufacturing tolerance(s) is more than one half the rate change desired. For example, assume you are considering a rate change from 475 to 500 lbs., which is a change of 5.3%. Further assume that the spring manufacturer’s tolerance is plus or minus 3%, a tolerance level, which is very common among manufacturers today. It is possible, therefore, that the rate for your 475 lb. Spring could range from 460 lbs. (475 X 97%) on the low end to 489 lbs. (475 X 103%) on the high end. The rate for your 500 lbs. spring could range from 485 lbs. (500 X 97%) to 515 lbs. (500 X 103%). In the worst case, you could be going from a 460 lb. Spring rate to a 515 lb. Spring rate, a 12% variation (remember you were looking for a 5.3% change!) that would dramatically affect your car’s handling, and leave you scratching your head, wondering what to do next!

Hyperco, invests in material and manufacturing technologies to ensure that their spring rates are accurate and consistent. While they guarantee plus or minus 2 percent tolerances, in actual experience, Hypercoils generally run within 1 percent tolerances, and they do not offer rates that overlap. Consistent rates and manufacturing tolerances allow their customers to develop “set ups” that repeat race to race, year to year, and coil to coil. This is one of the reasons the many of the top teams in all forms of motor racing use Hypercoils.

Hyperco Helper Springs

Helper Springs are enhancement springs for high-performance, aftermarket suspensions used in Motorsports, Street Performance and Off-Road applications. The main purpose of the Helper Spring is to support, or help, the main spring by keeping it in contact with its spring perch when the suspension is at full droop. Full droop occurs primarily during pit stops or when the vehicle becomes airborne. The flat wire design allows for a specifically designed solid height which helps with optimization of the total vehicle performance package.

Key Benefits of Helper Springs

  • A compact solid height

  • More usable deflection

  • Designed to take years of use at solid height without any compromise in performance

Hyperco Hydraulic Perches

Hyperco’s Hydraulic Spring Perches are suspension components used on coil-over springs designed to minimize lateral forces, resulting in maximized total performance of a vehicle.

Coil springs do not distribute their load evenly around the face of the end coils by nature. This results in lateral load. Hyperco’s hydraulic spring perches eliminate lateral loads by allowing the spring forces to remain centered on the damper.

By precise shaping of the sealing wall of both the spring perch and cylinder body, a perch can freely tilt as needed to evenly distribute the load over the face of the perch. The result is a reduction of bending load on the shock absorber of up to 96%, along with an enhancement in mechanical grip at the tire.

Key Benefits of Hydraulic Spring Perches

  • Reduces lateral load

  • Evenly distributes spring load

  • Reduces shock absorber internal frictions

  • Reduces bending load on the shock absorber

  • Improves mechanical grip at the tire
