Wiseco Mitsubishi 4G63 86.00 mm Bore 34.87 mm CH 0.00 CC Piston Set

Wiseco is well-known for making strong, reliable internal engine components, especially for performance applications. This Professional Series piston set is built for serious racers and builders who demand the best for their Mitsubishi 4G63 engine. These aren't just any pistons; they're designed from the ground up to handle the extreme stresses of heavy to severe duty race builds, giving you the confidence to push your engine's limits.

Each piston in this set is forged and machined right here in the USA from 2618 aluminum, a material chosen for its improved tensile strength under high temperatures and pressures. You'll find precision ring grooves, anti-detonation grooves, and other features designed to enhance ring seal and overall performance. Plus, they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly, even under demanding conditions. The fully machined crown and forced pin oiling further contribute to their durability and performance in high-stress environments.

This set includes four pistons, each with an 86.00 mm bore and a 34.87 mm compression height. They are designed as a direct replacement for the stock pistons in your 4G63 engine, making installation straightforward for a builder familiar with engine assembly. Please note that these pistons are not CARB approved and cannot be shipped to California.
