The H&R 60mm I.D. race spring is a single race spring for suspension tuning — 180mm length with a 50 N/mm (286 lbs/in) rate. Engineered in Germany from lightweight (hf) 54SiCr6 spring steel, the high-tensile alloy allows thinner coils that cut weight and increase travel versus typical springs. These race springs are factory pre-blocked to prevent permanent set, and H&R offers a wide selection of lengths and tender springs for custom setups.
