Wiseco Mitsubishi 4G63 85.00 mm Bore 34.87 mm CH -9.00 CC Piston Set

If you're rebuilding the engine in your Mitsubishi 4G63 for serious racing or heavy-duty performance, a strong set of pistons is crucial. This set from Wiseco is built from 2618 aluminum, a material chosen for its improved tensile strength, making it well-suited for the high stresses of competition. Each piston is forged and machined in the USA, ensuring precise dimensions for optimal performance and reliability.

These aren't just basic pistons; they're packed with features for demanding applications. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. The crown is fully machined for accuracy, and they include forced pin oiling to keep the wrist pins well-lubricated under extreme conditions. Plus, the ArmorGlide skirt coating helps reduce friction and resist seizure, contributing to quieter operation and longer life even in severe duty builds.

This set includes four pistons, each with an 85.00 mm bore and a 34.87 mm compression height. They are designed to handle heavy to severe duty performance builds, giving you the confidence to push your engine's limits. Please note that these pistons are not CARB approved and cannot be shipped to California.
