Wiseco Peugeot XU9J4 83.00 mm Bore 37.00 mm CH -1.00 CC Piston Set

If you're building a high-performance Peugeot XU9J4 engine, this Wiseco forged piston set is built to handle serious stress. These pistons are designed for heavy to severe duty race applications, meaning they're made to withstand the demands of competition where reliability is key. Each piston is forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for handling the high pressures and temperatures found in a race engine.

Wiseco has included several features to enhance performance and durability. You'll find precision ring grooves, an anti-detonation groove, and additional features designed to improve ring seal, all contributing to better combustion efficiency and power. The piston crown is fully machined for accuracy, and they also feature forced pin oiling to ensure the wrist pin stays well-lubricated under extreme conditions. To further reduce friction and wear, these pistons come with an ArmorGlide skirt coating, which helps prevent seizure and allows for quieter operation.

This set includes four pistons, each with an 83.00 mm bore and a 37.00 mm compression height. Please note that these pistons are not CARB approved and cannot be shipped to California. They are a robust option for builders looking for pistons that can handle the rigors of racing.
