Wiseco Mitsubishi 4G63 85.50 mm Bore 28.70 mm CH -12.00 CC Piston Set

What you get in this set are four forged pistons designed for the Mitsubishi 4G63 engine. These pistons are made from 2618 aluminum, which is a strong material chosen for its high tensile strength, especially important when you're pushing an engine hard. They're built with precision ring grooves, an anti-detonation groove, and other features to improve ring seal, all aimed at handling the demands of heavy to severe duty race builds.

Wiseco also applies an ArmorGlide skirt coating to these pistons. This coating helps reduce friction and resist seizure, while also contributing to quieter operation. The fully machined crown is another detail that shows these are made for serious performance. Plus, they feature forced pin oiling, which ensures the wrist pins get plenty of lubrication under high stress.

These pistons are specifically sized for an 85.50 mm bore and have a compression height of 28.70 mm. They are designed and machined in the USA. Keep in mind that these are not CARB approved and cannot be shipped to California. If you're building a high-performance 4G63 for racing or severe duty, these pistons are a solid option to consider.
