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/Dish requires no deburring or preparation and feature smooth flowing radii for excellent flame travel.
Pin fitting, wire locks, and rings included.
