Wiseco Mitsubishi 4G63 85.25 mm Bore 28.70 mm CH -21.00 CC Piston Set

Wiseco is well-known for making strong internal engine components, especially for performance applications. This Professional Series piston set is a prime example, built for serious racers and builders who push their Mitsubishi 4G63 engines hard. If you're rebuilding the top end for heavy or severe duty racing, these pistons are designed to handle that kind of stress.

These pistons are forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength for demanding conditions. They feature precision ring grooves, an anti-detonation groove, and other features to improve ring seal. The crown is fully machined, and they include forced pin oiling to keep things lubricated. Plus, they come with an ArmorGlide skirt coating that helps resist seizure, reduces friction, and makes for quieter operation. This set is designed to remove limits in your build.

This set includes four pistons, each with an 85.25 mm bore and a 28.70 mm compression height. Keep in mind 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.
