Wiseco Mitsubishi 4G63 82.00 mm Bore 30.25 mm CH -2.50 CC Piston Set

If you're rebuilding the engine in your Mitsubishi 4G63 for serious performance, a strong set of pistons is where you start. This set from Wiseco is built for those demanding applications where reliability under extreme stress is key. They're forged from 2618 aluminum, a material chosen for its improved tensile strength, making these pistons well-suited for heavy to severe duty race builds.

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. You'll also find an ArmorGlide skirt coating, which helps reduce friction and resist seizure, all while keeping operation quieter. The fully machined crown is another detail that contributes to their performance and durability in high-stress environments. Plus, they include forced pin oiling to ensure the wrist pins stay well-lubricated.

This set includes four pistons, each with an 82.00 mm bore and a 30.25 mm compression height. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a robust engine build focused on performance, this Wiseco piston set offers a solid foundation.
