Wiseco Mitsubishi 4G63 86.25 mm Bore 28.70 mm CH -12.00 CC Piston Set

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

You'll find precision ring grooves, an anti-detonation groove, and other features that help improve ring seal. The piston crowns are fully machined, and they come with forced pin oiling to keep things well-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 86.25 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. If you're building a high-performance Mitsubishi 4G63 engine, these pistons are a solid option for pushing the limits.
