The H&R 2.50" I.D. race spring is a single 14-inch coil rated at 170 lbs/in, designed for precise suspension tuning where longer free length is beneficial. Manufactured in Germany from (hf) 54SiCr6 spring steel, the high-tensile wire enables thinner coils to reduce weight and increase travel. H&R reports roughly 15% lower mass and around 10% more travel versus comparable springs; numerous main and tender lengths and rates are offered and springs ship pre-blocked.
