The H&R 2.50" I.D. race spring is a single 12-inch coil rated at 250 lbs/in, suited to serious suspension tuning and track-focused builds. Made in Germany from lightweight (hf) 54SiCr6 spring steel, the high-tensile alloy permits thinner wire for lower mass. Compared with typical competitors H&R springs are about 15% lighter and offer roughly 10% more travel; the lineup covers many main and tender spring lengths and rates and springs ship pre-blocked.
