Wiseco 1400 HD Mitsu EVO 8 - 4G63 Turbo -21cc Piston Shelf Stock Kit

Wiseco is well-known for making strong, reliable engine components, especially for high-performance applications. This Professional Series piston set is a prime example, built for serious racers and builders who demand the best for their Mitsubishi 4G63 Turbo engine. If you're putting together a heavy or severe duty race build, these pistons are designed to handle the extreme stress and heat that comes with pushing your engine to its limits.

These pistons are forged and machined right here 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, all contributing to better performance and durability under pressure. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly, which is a nice touch for a racing component. The fully machined crown and forced pin oiling further show the attention to detail in their construction.

This kit includes a set of four pistons, each with an 85.00 mm bore and a -21cc dish. They are designed with a 28.87 mm compression height and use a 0.866 inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California.
