The H&R 60mm I.D. race spring is a single race spring for suspension tuning — 180mm length with a 120 N/mm (686 lbs/in) rate. Manufactured in Germany from (hf) 54SiCr6 spring steel, H&R’s high-tensile wire allows thinner coils that reduce weight and provide greater travel than many competitors. These springs arrive pre-blocked to prevent permanent set, and the broad 60mm program offers many lengths and tender-spring options for precise handling setup.
