The H&R 60mm I.D. race spring is a single race spring for tuning — 180mm length with a 100 N/mm (571 lbs/in) rate. Engineered in Germany from lightweight (hf) 54SiCr6 spring steel, the high-tensile wire lets H&R use thinner coils to reduce mass and increase travel relative to many competitors. Springs are pre-blocked at the factory to prevent sagging, and the comprehensive 60mm program includes numerous lengths and tender springs for fine-tuning.
