Wiseco 1400 HD Mitsu EVO 8 - 4G63 Turbo -21cc Armor Plated Piston Shelf Stock Kit

Wiseco is well-known for making strong, reliable engine components for high-performance applications. This Professional Series forged piston set is built for serious racers and builders who push their engines hard. These pistons are designed and machined in the USA from 2618 aluminum, which gives them improved tensile strength for handling the demands of heavy to severe duty race builds.

You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The ArmorGlide skirt coating is a notable addition, helping to resist seizure, reduce friction, and contribute to quieter operation. The fully machined crown also features forced pin oiling, ensuring the wrist pin stays well-lubricated under extreme conditions. This set is intended for use in Mitsubishi 4G63 Turbo engines with a 4-cylinder configuration and a 85.50 mm bore.

This kit includes four pistons, each with a -21cc dish volume and a 28.87 mm compression height. The pin diameter is 0.866 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.
