Constructed from 2618 forged aluminum, these pistons are stronger and more durable than traditional designs. They feature deeper valve pockets to accommodate higher lift cams and milled cylinder heads, and are designed to accept a low friction .043/.043/3.0mm ring package. The dome configuration is compatible with most popular open chamber cylinder heads, including Brodix Head Hunter with up to 2.400" intake valves.
