Wiseco Mitsubishi 4G63 86.75 mm Bore 28.87 mm CH 0.00 CC Piston Set

This set includes four Wiseco forged pistons designed for the Mitsubishi 4G63 engine. These pistons are built from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for demanding performance applications. Each piston features precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. They also come with an ArmorGlide skirt coating, which helps resist seizure, reduces friction, and contributes to quieter operation.

Wiseco's Professional Series pistons are forged and machined in the USA. The fully machined crown and forced pin oiling are details that show these are built for heavy to severe duty race builds. If you're serious about pushing your engine's limits, these pistons are designed to handle the stress and heat associated with high-performance racing and building.

When rebuilding your engine, especially for racing, these pistons are a solid option. Remember that this set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
