H&R hrsRF180140

The H&R 60mm I.D. race spring is a single race spring for tuning and motorsport setups — 180mm length with a 140 N/mm (800 lbs/in) rate. Engineered in Germany from (hf) 54SiCr6 lightweight spring steel, H&R uses high-tensile wire to enable thinner coils, reducing weight and increasing travel versus typical springs. Factory pre-blocking prevents permanent set; the 60mm program provides a wide range of lengths and tender springs for detailed setup work.
