9907HC.040 - Claimer Hypereutectic Pistons

Coated Skirts for Less Friction
These pistons are ideal for racers on a budget: a cross between the economical Silvolite line & the high-performance KB line. By combining a hypereutectic alloy with the permanent mold process, the piston is thermally-efficient and strong yet lightweight. Tighter piston-to-wall clearances offer better ring seal & longevity.
