The H&R 2.50" I.D. race spring is a single 12-inch coil rated at 165 lbs/in, intended for fine suspension tuning and track-oriented setups. Manufactured in Germany from lightweight (hf) 54SiCr6 spring steel, the high-tensile wire allows thinner coils for reduced weight. H&R reports these springs run about 15% lighter and offer roughly 10% more travel than many competitors; a wide selection of lengths and rates is available and units ship pre-blocked.
