The H&R 60mm I.D. race spring, 140mm length with a 90 N/mm (514 lbs/in) rate, is part of H&R’s 2.50" I.D. race program crafted from lightweight (hf) 54SiCr6 spring steel in Germany. The high-tensile wire lets H&R use thinner material for lower weight and increased travel. Available in a wide range of lengths and rates, these springs are pre-blocked to resist setting and support precise suspension tuning.
