Wiseco Mitsubishi EVO X 4B11 Turbo -9cc 87mm Bore 8.8 CR HD Forged Piston Kit

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series forged piston kit is built for serious racers and builders who need parts that can handle extreme conditions. If you're working on a Mitsubishi EVO X with the 4B11 Turbo engine and pushing its limits, these pistons are designed to be a solid foundation for your build.

These pistons are forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength for demanding use. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal. The crown is fully machined, and they come with forced pin oiling to keep things lubricated. Plus, they have an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. This kit is designed and built to withstand heavy to severe duty performance applications, removing limits for your race build.

This kit includes four pistons, each with an 87mm bore and a 29.26mm compression height. The pin diameter is 0.9055 inches. Please note that this kit is not CARB approved and cannot be shipped to California. It is also subject to California's Prop 65 warning.
