Wiseco Mitsubishi 4G63 86.50 mm Bore 28.70 mm CH -12.00 CC Piston Set

What you get in this kit are four forged pistons, ready to be installed in your Mitsubishi 4G63 engine. These aren't your average pistons; they're built by Wiseco using 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for demanding race applications. The pistons are forged and machined right here in the USA, ensuring a high level of manufacturing control.

Wiseco has packed these pistons with features to handle serious power. You'll find precision ring grooves, an anti-detonation groove, and other enhancements designed to improve ring seal. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation. The fully machined crown and forced pin oiling are further details that show these pistons are made for heavy to severe duty performance builds. If you're building a high-performance 4G63 for racing or intense street use, these pistons are designed to help you push the limits.

Keep in mind that 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 procedures.
