The H&R 60mm I.D. race spring, 140mm length with a 100 N/mm (571 lbs/in) rate, comes from H&R’s 2.50" I.D. race line made in Germany from lightweight (hf) 54SiCr6 spring steel. The high-tensile alloy allows thinner wire for reduced weight and extra travel versus competitors. Offered across many lengths and rates, these main and tender springs are pre-blocked at the factory for consistent spring behavior and tunable suspension setup.
