Strange Engineering Hypercoil Springs

Strange Engineering has brought the premier spring manufacturer of CART, Indy, Formula One, and NASCAR to drag racing: Hyperco. The spring is an integral suspension component yet its importance has been overlooked by most drag racers. You'll find that the most successful race teams spend an immense amount of time adjusting and tuning their suspensions to gain an advantage. To get the best performance from a shock setup, springs must be able to work in harmony with the suspension.

Hypercoil Drag Racing Springs are cold wound from pre heat-treated SAE 9254 chrome silicon wire, and optimum wire diameter is used for the individual design. After coiling, the closed ends are ground, and springs are thermally stress-relieved, preset, and shot-peened. Completed springs are magnafluxed, powdercoated blue, and inspected for size and integrity. Additionally, Hyperco tests each coil for true rate and etches it into the spring. Such strict manufacturing standards yield springs with +/- 2% tolerance range (most are within 1%). Sold individually, all springs have 2.5" ID.
