Wiseco Mitsubishi 4G63 87.00 mm Bore 28.70 mm CH -12.00 CC Piston Set

Wiseco is well-known for making strong, reliable internal engine components, especially for performance applications. This Professional Series piston set is built for serious racers and builders who need parts that can handle extreme conditions. If you're putting together a heavy or severe duty race engine for a Mitsubishi 4G63, these pistons are designed to meet that challenge.

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for demanding builds. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal. You also get Wiseco's ArmorGlide skirt coating, which helps reduce friction, resist seizure, and makes for quieter operation. The fully machined crown and forced pin oiling are also notable features that contribute to their durability and performance under stress.

This set includes four pistons, each with an 87.00 mm bore, a 28.70 mm compression height, and a 0.866-inch pin diameter. Keep in mind these are not CARB approved and cannot be shipped to California. For builders pushing the limits, these pistons are a solid choice.
