Wiseco Peugeot XU10J4 86.00 mm Bore 39.16 mm CH -14.00 CC Piston Set

Wiseco's Professional Series forged piston set is built for the Peugeot XU10J4 engine, with a specific 86.00 mm bore size. These pistons are designed for serious racers and builders who need robust components for heavy to severe duty race applications. They are forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for handling the stresses of high-performance engines.

Each piston features precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal. The crown is fully machined for accuracy, and they incorporate forced pin oiling to ensure the wrist pin stays well-lubricated. A notable feature is the ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation. These are well-built pistons intended to handle demanding performance builds where reliability is paramount.

This set includes four pistons, designed as a complete package for rebuilding or upgrading your XU10J4 engine. Please note that these pistons are not CARB approved and cannot be shipped to California.
