Wiseco Peugeot XU9J4 84.00 mm Bore 37.00 mm CH -1.00 CC Piston Set

If you're building a high-performance Peugeot XU9J4 engine, this set of four forged pistons from Wiseco is designed to handle serious stress. These pistons are made from 2618 aluminum, chosen for its improved tensile strength, which is crucial when you're pushing an engine hard. They are forged and machined right here in the USA, ensuring a high level of precision throughout the manufacturing process.

Wiseco has included several features to boost performance and durability. You'll find precision ring grooves, an anti-detonation groove, and other features that help improve ring seal, meaning better compression and less blow-by. The piston crowns are fully machined for accuracy, and they come with forced pin oiling to keep the wrist pins well-lubricated under extreme conditions. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, even in demanding race applications.

This set is intended for heavy to severe duty race builds where reliability and strength are paramount. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a robust engine build, this Wiseco piston set offers a well-built foundation.
