The H&R 60mm I.D. race spring is a single race spring 160 mm long with a spring rate of 60 N/mm (approximately 343 lbs/in), suited for precision suspension tuning on performance and motorsport applications. Produced in Germany from lightweight 54SiCr6 spring steel, H&R’s 60mm lineup uses thinner high-tensile wire for around 15% lower weight and roughly 10% more travel than many competitors. The program includes numerous lengths and rates plus tender springs, and springs are pre-blocked to resist sag.
