The H&R 60mm I.D. race spring is a single main race spring (120mm length, 90 N/mm) designed for suspension tuning across street and track applications. Manufactured in Germany from (hf) 54SiCr6 spring steel, these springs are on average 15% lighter and offer about 10% more travel than many competitors. The H&R 60mm program provides extensive length and rate choices—80–300mm and 25–700 N/mm—includes tender springs, and arrives factory pre-blocked to resist sagging.
