The H&R 2.50 in I.D. race spring is a single-main coil suited to competition tuning. This 10 inch version is rated 150 lbs/in and manufactured from lightweight (hf) 54SiCr6 spring steel in Germany. H&R's construction yields lower weight and increased travel versus conventional springs; a wide range of lengths and rates allow tailored setups, and optional tender springs plus factory pre-blocking prevent settling.
