The H&R 60mm I.D. race spring, 140mm length with a 170 N/mm (971 lbs/in) rate, is made from special lightweight (hf) 54SiCr6 spring steel and manufactured in Germany. H&R’s high-tensile wire construction allows thinner coils for reduced weight and increased travel versus typical springs. The 60mm I.D. program includes a wide selection of main and tender springs, all pre-blocked to resist sagging and support precise tuning choices.
