Wiseco Mitsubishi 4G63 85.25 mm Bore 35.00 mm CH -17.00 CC Piston Set

If you're rebuilding the engine in your Mitsubishi 4G63 for serious racing or heavy-duty performance, a strong set of pistons is where you start. This Wiseco Professional Series piston set is built from the ground up for those demanding applications. They're forged from 2618 aluminum, which gives them improved tensile strength over cast aluminum, making them well-suited for the high stresses of racing.

Wiseco machines these pistons right here in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and features that improve ring seal. This helps ensure you get the most out of your engine build. They also come with an ArmorGlide skirt coating, which is designed to reduce friction and resist seizure, contributing to quieter operation and better durability under load. The fully machined crown and forced pin oiling are also notable features that speak to their performance-oriented design.

This set includes four pistons, each with an 85.25 mm bore and a 35.00 mm compression height. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a robust engine build intended for severe duty, this Wiseco set is a solid option.
