The H&R 60mm I.D. race spring is a single race spring 160 mm long with a spring rate of 200 N/mm (about 1142 lbs/in), intended for exacting suspension tuning where compact geometry and a high spring rate are needed. Made in Germany from lightweight 54SiCr6 spring steel, H&R’s 60mm series uses high-tensile thin wire to reduce weight by around 15% and increase travel by roughly 10% compared with common alternatives. A broad selection of lengths and rates is available, and mains are pre-blocked to avoid permanent set.
