The H&R 2.50" I.D. race spring is a single 14-inch coil rated at 150 lbs/in, aimed at suspension tuning where increased free length is needed. Manufactured in Germany from lightweight (hf) 54SiCr6 spring steel, the high-tensile wire allows thinner coils for lower mass and more travel. H&R reports their race springs are roughly 15% lighter with about 10% more travel than many competitors; main and tender options cover a broad array of lengths and rates and springs come pre-blocked.
