Product Details

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and heavy-duty performance builds. The 85.25 mm bore size and a compression ratio of 9.5:1 are specifically chosen for the Mitsubishi 4G63 7-bolt engine, aiming for a balance of power and reliability in high-stress applications.

Wiseco has incorporated several features to enhance durability and performance. The pistons include precision ring grooves, anti-detonation grooves, and additional features for improved ring seal, ensuring efficient combustion. A notable feature is the ArmorGlide skirt coating, which helps resist seizure, reduces friction, and contributes to quieter operation. The fully machined crown and forced pin oiling further support longevity under severe operating conditions. These pistons are engineered and machined in the USA, reflecting a commitment to quality construction for demanding engine builds.

This set includes four pistons, designed to be a direct replacement for your 4G63 7-bolt 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 refer to Wiseco's installation guidelines for specific details regarding assembly and break-in procedures for your build.
