Wiseco Mitsubishi 4G63 86.50 mm Bore 28.87 mm CH 0.00 CC Piston Set

If you're rebuilding the engine in your Mitsubishi 4G63 for serious performance, a set of Wiseco Professional Series pistons is a solid choice. These aren't your average pistons; they're built from the ground up for the demands of heavy to severe duty race applications. Wiseco starts with 2618 aluminum, a material known for its improved tensile strength, which is crucial when you're pushing an engine hard.

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 overall ring seal. This means you get better combustion control and less blow-by. They also come with an ArmorGlide skirt coating. This coating helps reduce friction, resists seizure if things get hot, and contributes to quieter operation. The fully machined crown and forced pin oiling further show that these pistons are designed to handle the stress of racing.

This set is for a 4G63 engine with an 86.50 mm bore and includes four pistons. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For builders focused on maximum performance and durability in a competition engine, these Wiseco pistons are a well-built option.
