Wiseco Mitsubishi 4G63 86.50 mm Bore 28.70 mm CH -4.00 CC Piston Set

If you're building a serious performance Mitsubishi 4G63 engine, Wiseco's Professional Series forged pistons are a solid choice. These pistons are made in the USA from 2618 aluminum, which offers improved tensile strength over other alloys, making them well-suited for heavy to severe duty race builds where durability is critical. The 86.50 mm bore size is a common upgrade for these engines, and the pistons are designed with precision ring grooves, anti-detonation features, and additional ring seal improvements to ensure reliable operation under high stress.

Wiseco also includes an ArmorGlide skirt coating on these pistons. This coating helps reduce friction, resist seizure, and can even contribute to quieter operation, all important factors when pushing an engine to its limits. The fully machined crown and forced pin oiling further demonstrate the attention to detail in their design, ensuring consistent performance and longevity. This set includes four pistons, ready for your high-performance build.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For builders in other states looking for robust internal engine components, this Wiseco set offers a well-built option designed for demanding applications.
