Wiseco Mitsubishi 4G63 85.00 mm Bore 28.87 mm CH 0.00 CC Piston Set

If you're rebuilding the engine for a performance Mitsubishi 4G63, especially for serious racing or heavy-duty applications, a strong set of pistons is crucial. These Wiseco Professional Series pistons are built from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for the demands of severe duty builds where reliability is key.

Wiseco machines these pistons right here in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling further contribute to their ability to handle tough conditions.

This set is designed for an 85.00 mm bore and includes four pistons. Keep in mind that these are not CARB approved and cannot be shipped to California. For a high-performance build, these pistons offer a solid foundation.
