Supertech designs and manufactures valve springs designed to do more than achieving the required pressure and lift. Our valve springs are designed to ensure natural harmonics of the spring for each application. Supertech springs are manufactured using superior materials in superclean chrome silicon vanadium alloy. Our springs are heat treated, stress relieved and shot peened to help improve the fatigue life of the spring.
