The H&R 60mm I.D. race spring is a single race spring 160 mm long rated at 50 N/mm (about 285 lbs/in), designed for adjustable suspension setups and track tuning. Manufactured in Germany from (hf) 54SiCr6 spring steel, the 60mm program employs high-tensile wire so coils can be thinner, producing roughly 15% less weight and about 10% more travel than comparable springs. H&R supplies a broad selection of main and tender springs and pre-blocks them to prevent permanent set.
