The H&R 60mm I.D. race spring, 85mm long with a 60 N/mm (343 lbs/in) rate, is constructed from (hf) 54SiCr6 lightweight spring steel and benefits from H&R's precision German manufacturing. Thinner wire can be used without loss of strength, yielding lighter springs and increased travel compared with many alternatives. All springs are pre‑blocked at the factory to avoid setting or sagging, and the 60mm program offers numerous length and rate options for careful suspension setup.
