Wiseco Mitsubishi 4G63 2.0L Gen 2 w/156mm Long Rod 85.5mm Bore +.020 Oversize -4 Dome Piston Set

This set includes four forged pistons from Wiseco, specifically made for Mitsubishi 4G63 2.0L engines. These aren't your average pistons; they're built from 2618 aluminum, forged and machined right here in the USA, giving them improved tensile strength for demanding applications. They feature precision ring grooves, anti-detonation grooves, and extra features to improve ring seal, all crucial for high-performance builds.

You'll also find an ArmorGlide skirt coating on these pistons. This coating helps reduce friction, makes operation quieter, and resists seizure, which is a big deal when you're pushing an engine hard. The fully machined crown and forced pin oiling are other details that show these pistons are designed for heavy to severe duty race builds. They are a +.020 oversize set, meaning they are 0.020 inches larger than the standard bore size, intended for engines that have been bored out to accommodate this size.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're serious about building a high-performance 4G63 engine for racing, these Wiseco pistons are a solid option designed to handle the stress.
