Product Details

Hyperco Bump Springs give your suspension a controlled progressive rate at the end of travel — the single most common upgrade on late-model, stock-car, and high-aero road-race cars for keeping a platform off the stops without sacrificing compliance. Used correctly, they raise front grip, protect your shock, and produce a far more predictable chassis under peak load.

Choose by ID, free length, and spring rate. Every Hyperco bump spring is wound from proprietary high-tensile steel in the USA and backed by Hyperco’s lifetime breakage warranty. Compatible with most major coilover platforms when paired with the correct bump cup or slider.

Hyperco has engineered precision suspension springs in the USA since 1970, supplying teams in Formula 1, IndyCar, NASCAR, Pirelli World Challenge, and top drift and time-attack programs. Every spring is wound from proprietary high-tensile steel and backed by a lifetime warranty against breakage.
