Supertech Valve Springs are made from high quality chrome silicon vanadium steel alloy. 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 harmonics remain under control and stress levels remain within material fatigue diagrams.

The Supertech cups are made of titanium alloy and machined by numerical control in order to obtain the best fit.
