Wiseco Mitsubishi 4G63 87.00 mm Bore 28.70 mm CH -4.00 CC Piston Set

When you're building a serious performance engine for your Mitsubishi 4G63, you need parts that can handle the stress. This set includes four forged pistons, precision-machined to an 87.00 mm bore. They feature a 28.70 mm compression height and a -4.00 cc dish, designed to work with specific cylinder head configurations for optimal performance.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength under high loads. Wiseco has included features like precision ring grooves, anti-detonation grooves, and additional ring seal enhancements to ensure reliable operation. The piston crowns are fully machined, and they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. Forced pin oiling is also incorporated to keep the wrist pins lubricated under extreme conditions.

Designed for heavy to severe duty race applications, these pistons are built to withstand the demands of high-performance builds. Please note that this piston set is not CARB approved and cannot be shipped to California.
