Valve Springs

Supertech Performance Dual Valve Springs are made with premium Super Clean Chrome Silicon Vanadium Steel alloy for higher performance and durability at high rpms and better memory. Computer designed to ensure that wire stress levels do not overpass the limits of stress defined in the diagrams of fatigue for long durability under extreme conditions. Computer software also allows us to make sure that the harmonics are well under control.

We have a couple of different spring rates for both All Motor and Turbo applications. Supertech Performance Dual Valve springs have proven themselves in a variety of applications to support over 800 horsepower and 10,500+ rpm.
