Wiseco Mitsubishi 4G63 85.25 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 piston set is built for serious racers and builders who need parts that can handle extreme conditions. These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength for demanding race builds.

You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. They also come with an ArmorGlide skirt coating that helps reduce friction and resist seizure, making for quieter operation and better durability. The fully machined crown and forced pin oiling are details that show these are built to withstand heavy to severe duty performance applications. This set includes four pistons, each with an 85.25 mm bore.

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 the core of your build.
