    SUPERTECH valve springs are made from a high grade chrome silicon vanadium steel alloy. This alloy delivers higher performance and better reliability at high engine speeds, together with improved structural memory. SUPERTECH performance valve springs are designed by computer so that harmonics stay under control and stress levels stay within the fatigue diagrams of the material.

    The SUPERTECH retainers are made from titanium alloy and CNC machined for the closest possible fit.
