The H&R 60mm I.D. race spring, 80mm long with a 60 N/mm (343 lbs/in) rate, is built from H&R's lightweight (hf) 54SiCr6 spring steel and precision German manufacturing. That material choice allows thinner wire for lower mass and increased travel versus many rivals. Each spring is pre‑blocked at the factory to prevent setting or sagging, and the 60mm lineup covers a broad range of lengths and rates to support bespoke suspension tuning for motorsport and high‑performance street cars.
