The JE Pistons forged piston kit for Mitsubishi 4G63 engines (2001–2007 Evolution VII–IX) offers a matched set of four pistons built for racing and high-output street use. JE’s FSR forging reduces skirt width and friction while 2618 aluminum provides high tensile strength. Application-dependent accumulator grooves and skirt coatings improve ring seal. The kit includes wrist pins, locks and JE Pro Seal rings, made in the USA.
