About this part

Product Details

Wiseco is well-known for making strong, reliable engine components for performance applications. For serious racers and builders working on a Mitsubishi Evo 4-9, their Professional Series forged pistons are a no-expense-spared option designed for heavy to severe duty race builds. These pistons are built to push the limits of your engine.

Each piston in this set is forged and machined in the USA from 2618 aluminum, which offers improved tensile strength for demanding conditions. They feature precision ring grooves, an anti-detonation groove, and additional features to improve ring seal. The asymmetric skirt design with ArmorGlide coating helps reduce friction, resist seizure, and operate more quietly. The crown is fully machined, and forced pin oiling is incorporated to keep things well-lubricated under high stress.

This set includes four pistons, each with an 85.00 mm bore and a 10.5:1 compression ratio. The pin diameter is 0.866 inches, and the compression height is 28.87 mm. Please note that these pistons are not CARB approved and cannot be shipped to California.
