The H&R 2.50 inch I.D. race spring, 8 inch length with a 950 lbs/inch rate, is crafted in Germany from lightweight (hf) 54SiCr6 spring steel for demanding motorsport setups. H&R says these springs are roughly 15% lighter and provide about 10% more travel compared with competitors. A wide range of lengths and rates are offered, and main springs are pre-blocked at the factory to prevent sagging under heavy use.
