Wiseco Mitsubishi 4G63 86.00 mm Bore 34.87 mm CH -9.00 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially for high-performance applications. This Professional Series piston set is built for serious racers and builders who need parts that can handle extreme conditions. These pistons are designed and machined in the USA from 2618 aluminum, which gives them improved tensile strength for demanding race builds.

Each piston features precision ring grooves, an anti-detonation groove, and other features to improve ring seal, ensuring efficient combustion even under heavy load. The fully machined crown is ready for precise assembly, and forced pin oiling helps keep the wrist pins lubricated. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. These are built to withstand heavy to severe duty performance applications, removing limits for your engine build.

This set includes four pistons, each with an 86.00 mm bore and a 34.87 mm compression height. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures.
