The H&R 60mm I.D. race spring is a single race spring for tuning — 180mm length with a 60 N/mm (343 lbs/in) rate. Made in Germany from lightweight (hf) 54SiCr6 spring steel, H&R’s high-tensile wire permits thinner coils for lower mass and increased travel relative to many competitors. Springs come factory pre-blocked to resist sag; the comprehensive 60mm program offers many lengths and tender springs for demanding motorsport setups.
