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
