Wiseco Mitsubishi 4G63 85.00 mm Bore 28.70 mm CH -12.00 CC Piston Set

If you're building a high-performance Mitsubishi 4G63 engine, Wiseco's Professional Series forged piston set is a solid choice. These pistons are made in the USA from 2618 aluminum, which offers improved tensile strength for demanding applications. They're designed for serious racers and builders who need parts that can handle heavy to severe duty use.

Wiseco machines these pistons with precision ring grooves, anti-detonation features, and additional ring seal improvements to ensure reliable performance under extreme conditions. The crown is fully machined, and they feature forced pin oiling for better lubrication. Plus, they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. This set includes four pistons, each with an 85.00 mm bore and a 28.70 mm compression height.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a serious engine build, these Wiseco pistons are made to remove your limits.
