The H&R 60mm I.D. race spring, 140mm long with a 120 N/mm (686 lbs/in) rate, belongs to H&R’s precision 2.50" I.D. race series made from (hf) 54SiCr6 spring steel in Germany. The high-tensile construction allows thinner wire for lower weight and roughly 10% more travel than many competitors. Available across a broad selection of lengths and rates, these pre-blocked springs support demanding motorsport setups and fine suspension tuning.
