Wiseco Mitsubishi 4G63 85.50 mm Bore 28.70 mm CH 1.90 CC Piston Set

If you're rebuilding the engine for a high-performance Mitsubishi 4G63, especially for serious racing or heavy-duty applications, a strong set of pistons is crucial. This Wiseco Professional Series piston set is built from the ground up to handle the demands of severe duty builds. They're forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength to resist deformation under extreme pressure.

Wiseco didn't cut any corners here. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which is vital for both power and engine longevity. The piston crowns are fully machined, and they even come with forced pin oiling to ensure the wrist pins stay well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and keep things running quieter, even under intense conditions.

This set includes four pistons, each with an 85.50 mm bore and a 28.70 mm compression height. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For builders aiming for maximum performance and durability in their 4G63 engine, this Wiseco set is a solid choice.
