The H&R 60mm I.D. race spring is a single race spring intended for performance tuning — 200mm length with an 80 N/mm (457 lbs/in) rate. Produced in Germany from lightweight (hf) 54SiCr6 spring steel, the high-tensile material allows thinner wire for less weight and more travel compared with many alternatives. Springs arrive factory pre-blocked to prevent sag, and the 60mm range includes many lengths and tender-spring options for precise setup.
