The H&R 2.50" I.D. race spring is a single 12-inch coil rated at 550 lbs/in for high-rate suspension tuning. Made in Germany from (hf) 54SiCr6 spring steel, the high-tensile wire permits thinner coils for less weight and more travel. H&R reports these springs are approximately 15% lighter with close to 10% more travel than many competitors; extensive main and tender spring lengths and rates are available and springs ship pre-blocked.
