Wiseco Peugeot XU9J4 83.50 mm Bore 37.00 mm CH 10.00 CC Piston Set

Forged from 2618 aluminum, these Wiseco pistons are built for serious racers and builders tackling heavy to severe duty performance applications. The 83.50 mm bore size is specific for the Peugeot XU9J4 engine, and the 37.00 mm compression height is a key measurement for setting up your engine's valve timing and piston-to-head clearance. Wiseco machines these pistons in the USA, ensuring precise tolerances for features like the anti-detonation grooves and additional ring seal improvements, all designed to help your engine perform reliably under extreme conditions.

You'll also find an ArmorGlide skirt coating on these pistons, which helps reduce friction and noise while also resisting seizure. This coating is beneficial for both performance and longevity, especially in high-stress builds. The crown is fully machined, and the design includes forced pin oiling to ensure the piston pin stays well-lubricated. This set comes complete with premium rings, ready for installation in your performance engine build.

Because these are designed for demanding race applications, it's important to note that they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
