Wiseco Mitsubishi 4G63 85.25 mm Bore 35.00 mm CH 1.00 CC Piston Set

This Wiseco piston set includes four forged pistons, designed specifically for the Mitsubishi 4G63 engine found in your 1990-1992 Eagle Talon, along with other compatible vehicles. These aren't your average pistons; they're built from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for demanding performance applications. The set comes complete with precision ring grooves, anti-detonation grooves, and features designed to enhance ring seal, all contributing to better engine performance and durability.

Wiseco has included their ArmorGlide skirt coating on these pistons. This coating helps reduce friction and resist seizure, which also contributes to quieter operation. The fully machined crown ensures a clean combustion chamber surface, and the forced pin oiling system helps keep the wrist pins properly lubricated under high stress. These pistons are engineered and machined in the USA, reflecting a commitment to quality construction for heavy to severe duty race builds where reliability is paramount.

When rebuilding or modifying your 4G63 engine for serious performance, these Wiseco pistons offer a robust foundation. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
