Wiseco Mitsubishi 4G63 85.00 mm Bore 28.70 mm CH -4.00 CC Piston Set

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

Each piston is forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength compared to other materials. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, ensuring efficient combustion and preventing detonation. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown is ready for whatever you throw at it, and forced pin oiling helps keep the wrist pin lubricated under high loads.

This set includes four pistons, each with an 85.00 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 4G63 and need pistons that can handle the demands of racing, this Wiseco set is a solid option.
