JE 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. Dome/Dish requires no deburring or preparation and features smooth flowing radii for excellent flame travel.
