Wiseco Mitsu 4G63 2.3L 85.00 Bore Standard 10.5:1 CR E85 Series Piston Shelf Stock Kit

This kit includes four forged pistons, designed for the Mitsubishi 4G63 engine. These pistons are built to handle the demands of serious racing and high-performance engine builds, specifically for applications using E85 fuel. They feature an 85.00 mm bore and a 10.5:1 compression ratio, making them a solid choice for those looking to push their engine's performance limits.

Crafted in the USA from 2618 aluminum, these pistons are forged and machined for improved tensile strength, which is crucial for withstanding the high pressures and temperatures found in severe duty race applications. They come with precision ring grooves, anti-detonation grooves, and additional features designed to enhance ring seal. The pistons also feature an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling further contribute to their durability and performance under extreme conditions.

These pistons are intended for heavy to severe duty race builds where reliability and performance are paramount. Please note that these pistons are not CARB approved and cannot be shipped to California.
