Obtain added performance from our forged piston assembly for our 414cc engine! Can also be used in the Honda GX390 engine at an .080" overbore! The piston is a flat top design with no valve reliefs. This piston will work with our 4.410" length billet aluminum connecting rod. This piston design incorporates a smaller skirt for less friction and weighs less than the stock piston. The piston pin lock is much stronger than the factory lock and the ends of the piston pin is tapered to increase the lock effectiveness. The piston pin is made from tool steel. The ring pack is thinner than the stock ring design for less cylinder wall drag! The second ring features a napier (hook) compression ring for better oil control. The top ring has a moly inlay for reduced wear and improved performance.
