Wiseco Mitsubishi 4G63 85.50 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 piston set is built for serious racers and builders who need parts that can handle heavy to severe duty race builds. These pistons are designed to remove your limits when you're pushing your engine hard.

Each piston is forged and machined in the USA from 2618 aluminum, which gives it improved tensile strength for demanding conditions. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal. The crown is fully machined, and they include forced pin oiling to keep things well-lubricated. A notable feature is the ArmorGlide skirt coating, which helps resist seizure, reduces friction, and contributes to quieter operation.

This set is for the Mitsubishi 4G63 engine and includes four pistons, each with an 85.50 mm bore. The compression height is 28.87 mm, and the pin diameter is 0.8661 inches. Please note 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.
