Wiseco Mitsubishi 4G63 2.0L Gen 2 w/ 156mm Long Rod 86.5mm Bore +.060 Oversize Dish Piston

If you're building a serious performance Mitsubishi 4G63 engine, these forged pistons from Wiseco are a solid choice. They're designed for the 2.0L Gen 2 engine, specifically for builds using a 156mm long rod, and come in an 86.5mm bore size that's +.060 inches oversize. Wiseco has packed these pistons with features aimed at durability and performance under demanding conditions.

These pistons are forged and machined in the USA from 2618 aluminum, which offers improved tensile strength for high-stress applications. You'll find precision ring grooves, an anti-detonation groove, and other features to help seal the combustion chamber effectively. The piston crown is fully machined, and they include forced pin oiling to keep things lubricated. Wiseco also applies an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. These are built to handle heavy to severe duty race builds, removing limits for serious racers and builders.

This set includes four pistons. 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.
