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.

As with Supertech, Ferrea reinforced valve springs are made from chrome vanadium steel and receive a heat treatment. These Ferrea Springs are developed so that harmonics and fatigue at high revs are under control (helps to avoid the Springs entering into resonance), they provide stability and reduced wear on the components of the Cylinder head. The design of these Springs also limits pressure loss.

Machined by numerical control, Ferrea cups are made of titanium.
