Description

Hypereutectic pistons with anti-friction skirt coating are manufactured from a aluminum alloy which contains 16 percent silicon for greater strength and wear resistance. By combining the hypereutectic alloy with the permanent mold process, the piston is strong, lightweight, and thermally-efficient. These pistons run tighter piston-to-wall clearances, improving ring seal and longevity. They are ideal for street, bracket racers and oval track.
