Wiseco Mitsubishi 4G63 85.25 mm Bore 28.87 mm CH 0.00 CC Piston Set

If you're building a high-performance Mitsubishi 4G63 engine, Wiseco's Professional Series forged piston set is a solid choice. These pistons are made in the USA from 2618 aluminum, which is known for its improved tensile strength, making them well-suited for demanding race applications where durability is key.

Wiseco machines these pistons with precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling further contribute to their ability to handle heavy to severe duty performance builds. This set includes four pistons, each with an 85.25 mm bore and a 28.87 mm compression height.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For serious racers and builders looking to push their 4G63 engine's limits, this set offers custom-level performance and durability.
