Claimer Hypereutectic Piston

Product images may differ from actual product appearance.

Coated skirts for less friction...

These pistons are ideal for the racer on a limited budget. They are a cross between the economy of the Silvolite line of pistons and the total performance of the KB line. 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.
