H&R hrsRF140500

The H&R 60mm I.D. race spring is a single race spring 140 mm long rated at 500 N/mm (about 2857 lbs/in), aimed at track-focused suspension tuning where exact spring rates and compact diameter are required. Crafted in Germany from lightweight (hf) 54SiCr6 spring steel, H&R’s 60mm range uses high-tensile, thinner wire to achieve roughly 15% lower weight and about 10% more travel than typical competitors. Main and tender springs come in many lengths and rates, and springs are pre-blocked to prevent permanent set.
