The H&R 2.50" I.D. race spring is a single 12-inch coil rated at 175 lbs/in for motorsport suspension tuning and custom setups. Produced in Germany from lightweight (hf) 54SiCr6 spring steel, the high-tensile wire permits thinner coils to lower mass and increase travel. H&R notes these springs are typically about 15% lighter with roughly 10% more travel than rivals; main and tender spring options cover many lengths and rates and arrive pre-blocked.
