Dome/Dish requires no deburring or preparation
2618 T6 high tensile forged aluminum
JE designs 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 and dishes feature smooth flowing radii for excellent flame travel.
1.2 x 1.2 x 2.5mm rings included
.866 x 2.250 straight wall carbon steel wrist pin included.
Pin fitting, wire locks, and rings included
