Wiseco Mitsu 4G63 2.3L 85.50 Bore .020 Oversize 10.5:1 CR E85 Series Piston Shelf Stock Kit

This kit includes four Wiseco E85 Series 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. They come with precision ring grooves, anti-detonation features, and additional ring seal improvements to ensure reliable operation under stress. The fully machined crown and forced pin oiling further contribute to their robust design.

The pistons in this set are .020 inch oversize, with a bore of 85.50 mm and a compression ratio of 10.5:1. They also feature an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. These are intended for heavy to severe duty race builds where durability and consistent performance are critical.

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.
