Wiseco Mitsubishi 4G63 86.50 mm Bore 34.87 mm CH 0.00 CC Piston Set

Wiseco is well-known for making strong, reliable engine components, especially for performance applications. This Professional Series piston set is a prime example, built for serious racers and builders who push their Mitsubishi 4G63 engines hard. These aren't your average pistons; they're designed from the ground up for heavy to severe duty race builds where every component needs to perform under extreme stress.

Forged and machined right here in the USA from 2618 aluminum, these pistons offer improved tensile strength, which is crucial for handling the high cylinder pressures found in performance engines. They feature precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, ensuring efficient combustion and preventing blow-by. The crown is fully machined for accuracy, and they come with forced pin oiling to keep the wrist pins properly lubricated. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, even under demanding conditions.

This set includes four pistons, each with an 86.50 mm bore and a 34.87 mm compression height. They are designed to withstand the rigors of severe duty performance applications, giving you the confidence to remove your limits. Please note that these pistons are not CARB approved and cannot be shipped to California.
