H&R 2.50" I.D. Race Springs
H&R 2.50" 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 technology, H&R 2.50" I.D. Race Springs are crafted from special 54SiCr6 spring steel and, for any given spring rate, are on average 15% lighter and have 10% more travel than competitors springs. Main springs range from 6" to 16" in length and are available in a wide selection of spring rates.

Tender Springs
H&R's 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&R springs, have been pre-blocked at the factory so they will never take a set or sag.
