Product Details

Hyperco Metric Series coilover springs are engineered for European and JDM platforms running 70mm ID coilover dampers — KW, Bilstein, H&R, Öhlins, HKS, TEIN, and most factory-equipped track-spec cars. Expect tighter rate tolerance, longer fatigue life, and less sag than OE replacement springs — the right spring for drivers running back-to-back track days or time-attack programs.

Pick free length and spring rate from the variant dropdown; each spring is sold individually and built in the USA. Lifetime warranty against breakage, paired perfectly with Hyperco Helper Springs or a Hydraulic Spring Perch for multi-stage corner-weight tuning.

About Hyperco

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.
