Wiseco Mitsubishi 4G63 85.50 mm Bore 28.70 mm CH -4.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and performance engine builds. The 85.50 mm bore size is a common upgrade for Mitsubishi 4G63 engines looking to increase displacement and power. Wiseco machines these pistons in the USA, ensuring a high level of precision throughout the manufacturing process.

These pistons feature an ArmorGlide skirt coating, which helps reduce friction and resist seizure, crucial for engines that see heavy or severe duty. You'll also find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, all contributing to better combustion efficiency and durability under high stress. The fully machined crown and forced pin oiling further enhance their ability to handle extreme conditions.

This set includes four pistons, designed to replace the factory units in your Mitsubishi 4G63 engine. While these are built for performance, remember they are not CARB approved and cannot be shipped to California. For builders aiming for maximum performance and reliability in a 4-cylinder race application, this Wiseco piston set is a solid choice.
