Wiseco Mitsubishi 4G63 2.0L Gen 2 w/156mm Long Rod 85.5mm Bore +.020 Oversize +1.9 Dome Piston Set

These Wiseco pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, making them well-suited for the demands of performance engine builds. This set is specifically for the Mitsubishi 4G63 2.0L engine, featuring a 156mm long rod design and an 85.5mm bore, which is +.020 inches oversize from the factory specification. The +1.9 dome design is engineered to work with specific compression ratios, and the pistons are fully machined for precise fitment and performance.

Wiseco has incorporated several features to enhance durability and performance in severe duty applications. The pistons include an anti-detonation groove and additional ring seal features to help maintain compression and prevent detonation. They also come with an ArmorGlide skirt coating, which is designed to reduce friction, resist seizure, and operate more quietly. The forced pin oiling system ensures the wrist pins receive adequate lubrication, a critical factor in high-performance engines.

This set includes four pistons, precision ring grooves, and is designed for builders who are pushing their engines hard. While these pistons are built for serious racing, please note they are not CARB approved and cannot be shipped to California. For a complete engine build, ensure you have all necessary supporting components and refer to manufacturer instructions for proper installation.
