The H&R 60mm I.D. race spring, 140mm length with a 110 N/mm (629 lbs/in) rate, is built from special lightweight (hf) 54SiCr6 spring steel and manufactured in Germany. H&R’s high-tensile wire yields a lighter coil with increased travel compared to typical springs. The 60mm I.D. program includes many lengths and rates plus tender spring options, all pre-blocked to minimize set and provide reliable behavior for motorsport and custom tuning applications.
