Wiseco Mitsubishi 4G63 86.50 mm Bore 28.70 mm CH 1.90 CC Piston Set

If you're rebuilding the engine for a performance Mitsubishi 4G63, especially for racing or heavy-duty use, you need pistons that can handle the stress. Wiseco's Professional Series forged pistons are built for those demanding applications. They're made from 2618 aluminum, which gives them improved tensile strength compared to cast aluminum, making them a solid choice for high-performance builds where reliability is key.

These pistons aren't just strong; they're also packed with features to help them perform. They have precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which is crucial for maintaining compression and power under extreme conditions. The crown is fully machined for accuracy, and they come with forced pin oiling to keep the wrist pins lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and resist seizure, contributing to quieter operation and longer life even in severe duty scenarios.

This set includes four pistons, each with an 86.50 mm bore and a 28.70 mm compression height. Remember, these pistons are not CARB approved and cannot be shipped to California. They are designed and machined in the USA.
