The H&R 60mm I.D. race spring is a single race spring 160 mm long with a spring rate of 220 N/mm (approximately 1256 lbs/in), designed for high-load suspension applications where compact diameter and firm rates are required. Manufactured in Germany from lightweight (hf) 54SiCr6 spring steel, H&R’s 60mm program leverages high-tensile thin wire to deliver about 15% less weight and roughly 10% more travel than many competing springs. H&R offers many lengths and rates and provides pre-blocked mains to resist sag.
