The H&R 60mm I.D. race spring, 140mm length with a 130 N/mm (743 lbs/in) rate, is crafted from lightweight (hf) 54SiCr6 spring steel using German manufacturing. The high-strength wire enables thinner coils that reduce mass and increase travel relative to standard springs. Offered across an extensive range of lengths and spring rates, H&R’s 60mm I.D. program includes tender springs and pre-blocked mains for consistent performance and setup flexibility.
