The H&R 60mm I.D. race spring, 140mm long with a 360 N/mm (2,055 lbs/in) rate, is produced in Germany from special lightweight (hf) 54SiCr6 spring steel as part of the 2.50" I.D. race series. The high-tensile wire lets H&R use thinner coils that cut weight and add travel versus many competitors. This extensive 60mm program includes varied lengths and rates, tender springs for extra travel, and pre-blocked mains to prevent settling and enable precise tuning.
