The H&R 60mm I.D. race spring, 130mm long with a 25 N/mm (143 lbs/in) rate, is built from special lightweight (hf) 54SiCr6 spring steel and benefits from H&R's precision German manufacture. Thinner wire can be used without losing strength, producing lighter springs with more travel than many alternatives. All springs are pre‑blocked at the factory to resist setting or sagging, and the 60mm program offers a broad selection of lengths and rates for tailored suspension setup.
