Wiseco Mitsubishi 4G63 86.00 mm Bore 28.70 mm CH 1.90 CC Piston Set

Wiseco is well-known for making strong, reliable engine components, especially for performance applications. This Professional Series piston set is a prime example, designed for serious racers and builders who push their Mitsubishi 4G63 engines hard. These aren't your average pistons; they're packed with features aimed at delivering both performance and durability when you need it most.

Forged in the USA from 2618 aluminum, these pistons are built for improved tensile strength, which is crucial for handling the high stresses of racing. They come with precision ring grooves, anti-detonation grooves, and other features to improve ring seal, helping to keep combustion gases contained and power up. The pistons also feature an ArmorGlide skirt coating that helps reduce friction and noise, while also resisting seizure. The fully machined crown is ready for your build, and forced pin oiling ensures the wrist pins stay well-lubricated under extreme conditions.

This set is designed and built to withstand heavy to severe duty performance applications, so you can remove your limits and focus on the track. Remember, these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly details.
