Wiseco Mitsubishi 4G63 85.25mm Bore 9.2:1 CR -10.25cc Dome Piston Set

If you're building a high-performance Mitsubishi 4G63 engine, this set of Wiseco forged pistons is a solid choice for serious racers and builders. These pistons are specifically made for the 4G63 engine, with an 85.25mm bore and a 9.2:1 compression ratio, designed to handle the demands of heavy to severe duty race applications. They are engineered and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for high-stress engine builds.

Wiseco has packed these pistons with features aimed at maximizing performance and durability. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The crown of each piston is fully machined for accuracy, and they include forced pin oiling to ensure the wrist pins stay well-lubricated under extreme conditions. Additionally, these pistons come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation. This attention to detail means these pistons are built to withstand the rigors of competitive racing and extreme performance builds.

This set includes four pistons, ready for installation in your 4G63T engine. Please note that these pistons are not CARB approved and cannot be shipped to California. It's always a good idea to consult your engine builder or manufacturer's specifications for any additional components or clearances needed for your specific build.
