Wiseco Mitsubishi 4G63 Gen 2 85mm Bore 9.5:1 CR -4cc Dome Shelf Stock Piston Kit

This kit gets you four Wiseco forged pistons, ready to go into your Mitsubishi 4G63 Gen 2 engine. These pistons are built for serious performance, featuring an 85mm bore and a 9.5:1 compression ratio with a -4cc dome shelf. They're designed to handle the demands of heavy to severe duty race applications, so you can push your engine hard.

Wiseco crafts these pistons in the USA from 2618 aluminum, which offers improved tensile strength for durability under stress. You'll find precision ring grooves, anti-detonation grooves, and other features to enhance ring seal. They also come with an ArmorGlide skirt coating that helps reduce friction and noise, while also resisting seizure. The fully machined crown and forced pin oiling further contribute to their robust design, making them a solid choice for builders who need reliable performance.

When installing these pistons, remember they are not CARB approved and cannot be shipped to California. It's always a good idea to consult the manufacturer's installation instructions for specific details regarding pin fitment and assembly.
