Wiseco Mitsubishi 4G63 85.25 mm Bore 34.87 mm CH -9.00 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series piston set is built for Mitsubishi 4G63 engines and is designed for serious racers and builders who push their engines hard. If you're rebuilding a performance engine that will see heavy or severe duty, these pistons are made to handle that kind of stress.

These pistons are forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength for demanding builds. They feature precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The crown is fully machined, and they also come with forced pin oiling to keep things lubricated. Plus, they have an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly.

This set includes four pistons, each with an 85.25 mm bore. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For severe duty builds, consider pairing these with other high-performance engine components to complete your setup.
