Wiseco Mitsubishi 4G63 85.00 mm Bore 28.70 mm CH 1.90 CC Piston Set

This is a set of four forged pistons from Wiseco, designed for Mitsubishi 4G63 engines. These pistons are built with 2618 aluminum, which offers improved tensile strength, making them suitable for heavy to severe duty race applications. They feature precision ring grooves, anti-detonation grooves, and additional features to improve ring seal, all contributing to better performance and durability under demanding conditions.

Wiseco has included an ArmorGlide skirt coating on these pistons. This coating helps reduce friction and resist seizure, while also contributing to quieter operation. The fully machined crown is designed for optimal combustion, and the forced pin oiling system ensures proper lubrication to the piston pin. These pistons are forged and machined in the USA, reflecting a commitment to quality construction for serious racers and builders.

If you're rebuilding a high-performance Mitsubishi 4G63 engine for racing or severe duty use, these Wiseco pistons are a solid option. 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.
