The H&R 2.50 in I.D. race spring is a single main spring built for competition suspension use. This 10 inch unit carries a 550 lbs/in rate and is manufactured from lightweight (hf) 54SiCr6 spring steel in Germany. H&R's approach yields lighter springs with more travel compared to typical designs; the wide selection of lengths and rates enables tailored tuning, while tender springs and factory pre-blocking minimize set and sag over the life of the spring.
