Wiseco Mitsubishi 4G63 86.00 mm Bore 28.70 mm CH -4.00 CC Piston Set

Wiseco is well-known for making strong, reliable engine components for performance builds. This Professional Series forged piston set is a prime example, designed specifically for demanding Mitsubishi 4G63 applications. If you're building a serious performance engine, these pistons are built to handle the stress of heavy to severe duty racing.

These pistons are forged and machined in the USA from 2618 aluminum, which offers improved tensile strength for high-stress environments. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal. The crown is fully machined for accuracy, and they include forced pin oiling to keep things lubricated. For reduced friction and quieter operation, the piston skirts are coated with ArmorGlide, which also helps resist seizure.

This set includes four pistons, each with an 86.00 mm bore and a 28.70 mm compression height. Please note that these pistons are not CARB approved and cannot be shipped to California. They are intended for serious racers and builders looking to remove their limits.
