JE Pistons Sport Compact Pistons 279931

JE Pistons sport compact pistons are specifically engineered for extreme applications, up to and including professional competition. In this environment, the higher compression ratios, highest boost, or heavy nitrous usage necessitate the higher tensile strength 2618 aluminum alloy. Their dome/dish requires no deburring or preparation and features smooth-flowing radii for excellent flame travel. A pin fitting, wire locks, and rings are included.Brand: JE Pistons
