The H&R 60mm I.D. race spring, 80mm long with a 15 N/mm (86 lbs/in) rate, comes from H&R's 60mm program built using (hf) 54SiCr6 spring steel for lighter weight and added travel. The advanced wire allows thinner coils without sacrificing strength, providing roughly 10% more travel compared with many rivals. These springs are pre‑blocked at the factory to resist setting or sagging and are offered in many lengths and rates to support precise suspension tuning.
