Hyperco Coil Spring Set
Hyperco Coil Spring Sets: Motorsport Precision for Every Build
When it comes to coil spring sets, few names carry the engineering credibility of Hyperco. Born in the heart of professional motorsports, Hyperco's flagship Hypercoils™ line has been the suspension spring of choice for circle track racers, IndyCar teams, and road course competitors for decades. Every Indy 500 winning car for the past half century has used Hyperco springs — a testament to what their coil spring sets deliver when championships are on the line.
Two Signature Coil Spring Set Designs
Hyperco's coil spring set lineup is anchored by two proprietary engineering platforms, each optimized for different performance demands:
- Optimum Body Diameter (OBD): The OBD design features a unique concept that adjusts the body diameter of the spring relative to the end coils, enabling Hyperco to take full advantage of their ultra-high tensile spring materials by optimizing the applied stress. This is the standard platform for most Hyperco coilover spring sets.
- Ultra High Travel (UHT): UHT springs are designed specifically for light rate and 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 features a larger "body bulge" over the standard OBD design, allowing for additional deflection, rate linearity, and resistance to bowing.
- Dual Rate UHT: Hyperco's Dual Rate UHT coil-over springs take competition coil-over design to the next level, essentially providing the performance of an optimized stacked spring set-up in a single spring. These springs combine a relatively low initial spring rate to absorb minor undulations and increase grip, with a precise transition point to a secondary higher spring rate to improve roll control during cornering.
Materials and Manufacturing That Make a Difference
Hyperco's chrome silicon wire coil-over springs bring NASCAR technology to your car and carry a lifetime manufacturer's warranty. That warranty is backed by uncompromising manufacturing tolerances: Hyperco invests in material and manufacturing technologies to ensure spring rates are accurate and consistent, guaranteeing plus or minus 2 percent tolerances — and in actual experience, Hypercoils generally run within 1 percent tolerances, with no overlapping rates offered.
Advanced metallurgy, spring winding, and heat treating techniques result in springs that won't lose ride height or rate, and Hypercoils are finished with a tough blue epoxy powder coat that offers unmatched durability. The blue epoxy powder coating is applied thin yet remains flexible, unlike competitors' plastic coatings which can build up over time and possibly change the overall spring rate.
Why Rate Consistency Matters in a Coil Spring Set
Consistent rates and manufacturing tolerances allow customers to develop setups that repeat race to race, year to year, and coil to coil — which is one of the reasons many of the top teams in all forms of motor racing rely on Hypercoils. Whether you're tuning a circle track car, building a coilover street setup, or preparing a dedicated road racing machine, having springs that perform exactly as rated eliminates a major variable from the equation.
Hyperco coilover springs redefine suspension customization by providing a diverse range of free lengths and rates, giving suspension designers the ability to craft a motion ratio tailored for optimal control over an extensive wheel travel range. Hyperco is manufactured in the USA and is a proud NASCAR Competition Partner.
