Hypereutectic pistons are cast using hyper eutectic alloy, that is a metallic alloy which has a composition beyond the eutectic point. Hypereutectic pistons are made of an aluminum alloy which has much more silicon present than is soluble in aluminum at the operating temperature.

By adding silicon to the piston's alloy, the piston expansion is dramatically reduced to specify reduced clearance between the piston and the cylinder wall. Silicon itself expands less than aluminium. Another benefit of adding silicon is that the piston becomes harder and is less susceptible to scuffing which can occur when a soft aluminum piston is cold-revved in a relatively dry cylinder on start-up or during abnormally high operating temperatures.

The Performance Dish Top Hypereutectic Pistons, Moly Piston Rings and Gudgeon Pins are made to the highest standard and exceed original manufacturers specifications for longevity, smooth operation and maximum performance.
