The Manley Platinum Series forged piston set for the Mitsubishi 4G63 stroker uses domestic 2618 alloy forgings in a four-piece set with an 85.5mm bore and -22cc dish. These pistons pair cam-and-barrel skirt profiles with exacting ring lands and grooves plus premium wrist-pin options; Manley's fixturing and machining standards preserve ring groove-to-skirt squareness for dependable sealing in high-output 4G63 builds.
