H&R hrsRF160180

The H&R 60mm I.D. race spring is a single race spring 160 mm long with a spring rate of 180 N/mm (approximately 1028 lbs/in), aimed at precise suspension setup for track or high-speed street use. Manufactured in Germany from (hf) 54SiCr6 spring steel, H&R’s 60mm program uses thinner high-tensile wire for about 15% less weight and roughly 10% more travel than many competitors. The line includes a wide range of main and tender springs, and main springs arrive pre-blocked to resist sag.
