Wiseco Mitsubishi Lancer Evo 8 4G63 Turbo Piston Shelf Stock Kit

Wiseco is well-known for making strong, reliable internal engine components, especially for performance applications. This Professional Series piston set is built for serious racers and builders working on a Mitsubishi Lancer Evo 8 with the 4G63 turbo engine. These aren't just stock replacements; they're designed from the ground up to handle the demands of heavy to severe duty race builds, giving you the confidence to push your engine's limits.

Each piston in this set is forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength under high stress. You'll find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal, which is critical for power and engine longevity. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown ensures accuracy and performance, and the forced pin oiling system keeps the wrist pins lubricated under extreme conditions.

This kit includes four pistons, each with an 85.25 mm bore and a 35.00 mm compression height, using a 0.8661-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance 4G63 engine and need pistons that can withstand serious abuse, this Wiseco set is a solid option.
