The H&R 60mm I.D. race spring is a single main race spring (100mm length, 280 N/mm) suited for suspension tuning and motorsport setups. Engineered in Germany from lightweight (hf) 54SiCr6 spring steel, these springs are about 15% lighter and provide roughly 10% more travel than comparable designs. The comprehensive 60mm program offers 80–300mm lengths and 25–700 N/mm spring rates, plus tender springs and factory pre-blocking to reduce sag over time.
