In house forging has allowed JE to develop proprietary Aligned Grain Flow Technology forging technology that directs the grain flow of the aluminum to flow around critical areas of the piston, increasing strength. Lateral gas ports channel combustion gases to the back of the top ring groove, which adds pressure behind the compression ring to keep it pushed against the
