H&R hrsRF180180

The H&R 60mm I.D. race spring is a single race spring for suspension tuning — 180mm length with an 180 N/mm (1028 lbs/in) rate. Made in Germany from (hf) 54SiCr6 spring steel, the high-tensile material allows thinner wire for lower weight and increased travel relative to many competitors. These springs are factory pre-blocked to prevent permanent set; H&R’s extensive 60mm program offers many lengths and tender springs for fine adjustment.
