Wiseco Mitsubishi 4G63 85.25 mm Bore 28.87 mm CH 0.00 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series forged piston set is built for Mitsubishi 4G63 engines, designed for serious racers and builders who push their engines hard. These aren't just standard pistons; they're packed with features aimed at high-performance and durability, making them suitable for heavy to severe duty race builds.

Crafted from 2618 aluminum in the USA, these pistons offer improved tensile strength, which is crucial for handling the extreme pressures of a performance engine. They feature precision ring grooves, anti-detonation grooves, and other features to improve ring seal, ensuring efficient combustion and preventing blow-by. The pistons also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling further contribute to their robust design for demanding applications.

This set includes four pistons, each with an 85.25 mm bore and a 28.87 mm compression height. While these pistons are built for extreme performance, please note they are not CARB approved and cannot be shipped to California. If you're building a high-output 4G63 engine, these pistons are a solid option to consider for the core of your build.
