The H&R 2.50" I.D. race spring is a single 12-inch coil rated at 500 lbs/in for demanding suspension tuning and competition use. Produced in Germany from lightweight (hf) 54SiCr6 spring steel, the high-tensile alloy allows thinner wire for reduced mass and increased travel. H&R notes an average of 15% lower weight and about 10% more travel compared with many rivals; the program covers many lengths and rates and springs are pre-blocked at the factory.
