The H&R 2.50" I.D. race spring is a single 12-inch coil rated at 450 lbs/in for motorsport and heavy-duty tuning needs. Manufactured in Germany from (hf) 54SiCr6 spring steel, the high-strength wire allows thinner coils to minimize weight and maximize travel. H&R indicates these springs are roughly 15% lighter with about 10% more travel than comparable products; a broad selection of main and tender lengths and rates is available and springs arrive pre-blocked.
