Wiseco Mitsu 4G64 w/4G63 Heads 10.5:1 E85 Piston Kit

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series piston kit is built for serious racers and builders who need reliable parts for heavy to severe duty builds. These pistons are designed to handle the demands of high-performance engines, giving you the confidence to push your build further.

Each piston is forged and machined in the USA from 2618 aluminum, which offers improved tensile strength for durability under stress. They feature precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. The crown is fully machined, and they include forced pin oiling to ensure proper lubrication. Plus, they come with an ArmorGlide skirt coating that helps resist seizure, reduces friction, and makes for quieter operation. This kit is specifically set up for E85 fuel with a 10.5:1 compression ratio and an 85.50 mm bore, making it a solid choice for those building a performance Mitsubishi 4G64 engine using 4G63 heads.

This set includes four pistons, ready for your engine build. Please note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
