Description

The JE Pistons 330159S is a set of forged dome pistons designed for circle track and drag racing applications. These pistons are up to 100 grams lighter than traditional full round pistons, offering increased strength and durability due to their FEA-designed forging. They feature deeper valve pockets to accommodate higher lift cams and milled cylinder heads, and accept a low friction .043/.043/3.0mm ring package.
