Supertech valve springs are made with premium Super Clean Chrome silicon Vanadium Steel alloy for the highest performance and durability at high rpm's. Valve springs are computer designed to ensure that wire stress levels do not surpass the limits of stress defined in the diagrams of fatigue for long durability under extreme conditions. Additionally our springs are properly designed to control the dominant harmonics, while providing the needed stability to reduce valvetrain component wear. All Supertech Valve Springs are heat treated and stress-relieved, which dramatically increases the spring's life. Finally, Supertech valve springs provide the stability needed for high lift, high rpm racing engines while minimizing the load loss of today's agreesive valvetrain applications.
