The H&R 2.50 in I.D. race spring is a single main coil for track or heavy-duty suspension tuning. This 10 inch spring is rated 350 lbs/in and manufactured from lightweight (hf) 54SiCr6 spring steel in Germany. H&R's design yields lighter mass and more travel versus competitors, and the broad spring program includes many lengths and rates, with tender springs and factory pre-blocking to prevent setting and preserve ride height.
