The H&R 60mm I.D. race spring is a single race spring sized for motorsport tuning — 160mm length with a 240 N/mm (1370 lbs/in) rate. Manufactured in Germany from lightweight (hf) 54SiCr6 spring steel, the high-tensile wire lets H&R use thinner coils for roughly 15% less weight and about 10% more travel than many competitors. Factory pre-blocking prevents settling; tender springs are also available for demanding setups.
