Wiseco Mitsubishi 4G63 87.00 mm Bore 28.87 mm CH 0.00 CC Piston Set

Wiseco is well-known for making strong, reliable engine components, especially for performance applications. This Professional Series forged piston set is a prime example, built specifically for the Mitsubishi 4G63 engine. If you're building a serious race motor or a heavy-duty performance engine, these pistons are designed to handle the extreme demands you'll put on them.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength under high stress. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal, which is crucial for maintaining compression and preventing blow-by in a high-performance engine. The crown of each piston is fully machined, and they come with forced pin oiling to ensure the wrist pins stay well-lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also resisting seizure, keeping your engine running smoother and longer under load.

This set includes four pistons, each with an 87.00 mm bore and a 28.87 mm compression height. They are designed for sport compact applications and are built to withstand severe duty performance. Keep in mind these are not CARB approved and cannot be shipped to California. For serious builders, these pistons offer a solid foundation for a powerful and durable engine.
