The H&R 60mm I.D. race spring is a single race spring 160 mm long with a spring rate of 90 N/mm (approximately 514 lbs/in), intended for suspension tuning where a firmer spring is required without increasing diameter. Produced in Germany from (hf) 54SiCr6 spring steel, this 60mm program leverages high-tensile, thinner wire for about 15% less weight and roughly 10% more travel than typical competitor springs. H&R offers extensive lengths and rates and pre-blocks springs to prevent sag during use.
