H&R 2.50ÃÃÃÃ¢ÃÃÃÃÃÃÃÃ I.D. Race Springs are made with extremely high tensile strength wire alloy which allows the use of a thinner wire thickness. Manufactured using advanced materials and precision technology in Germany, H&R 2.50ÃÃÃÃ¢ÃÃÃÃÃÃÃÃ I.D. Race Springs are crafted from special lightweight (hf) 54SiCr6 spring steel. For any given spring rate, they are on average 15% lighter and have 10% more travel than competitorsÃÃÃÃ¢ÃÃÃÃÃÃÃÃ springs. Main springs range from 6ÃÃÃÃ¢ÃÃÃÃÃÃÃÃ to 16ÃÃÃÃ¢ÃÃÃÃÃÃÃÃ in length and are available in a wide selection of spring rates.
H&R 2.50ÃÃÃÃ¢ÃÃÃÃÃÃÃÃ I.D. Tender Springs are made of trapezoidal (flat rather than round) spring wire and have a low block height for maximum travel. These springs are designed for demanding motorsport environments, and like all H&R springs, have been pre-blocked at the factory so they will never set or sag.
