Race Springs are made with extremely high tensile strength wire alloy which allows the use of a thinner wire. Manufactured using advanced materials and precision technology in Germany, H\u0026amp;R 2.50\" 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 competitors' springs. Main springs range from 6\" to 18\" in length and are available in a wide selection of spring rates.  TENDER SPRINGS: H\u0026amp;R 2.50\" 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\u0026amp;R'springs, have been pre-blocked at the factory so they will never set or sag. The H\u0026amp;R 6\"mm I.D.
