Wiseco Mitsubishi 4G63 86.00 mm Bore 28.70 mm CH -12.00 CC Piston Set

If you're building a high-performance Mitsubishi 4G63 engine, Wiseco's Professional Series forged piston set is a solid choice. These pistons are made in the USA from 2618 aluminum, which gives them improved tensile strength for handling the demands of serious racing and heavy-duty builds. They're designed to be a no-compromise component for racers and builders who need top-tier performance and durability.

Wiseco has packed a lot of features into these pistons to ensure they perform under pressure. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. The piston crowns are fully machined, and they include forced pin oiling to keep things well-lubricated. Plus, they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. These are built to withstand heavy to severe duty performance applications, making them a reliable option for extreme builds.

This set includes four pistons, each with an 86.00 mm bore and a 28.70 mm compression height. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for sport compact applications.
