    SUPERTECH valve springs are made from a High quality chrome silicon vanadium alloy steel. This alloy has the advantage of offering superior performance and reliability, especially at high revs, and has better structural memory. SUPERTECH reinforced valve springs are computer designed to ensure that harmonics remain under control and stress levels remain within material fatigue diagrams.

    SUPERTECH valve springs are made of titanium alloy and CNC machined to achieve the best fit.
