Wiseco Peugeot XU9J4 83.00 mm Bore 37.00 mm CH 10.00 CC Piston Set

If you're building a high-performance Peugeot XU9J4 engine, these forged pistons from Wiseco are a solid choice. They're designed to handle the demands of serious racing and heavy-duty builds, giving you the confidence to push your engine hard. Wiseco has packed these pistons with features aimed at both durability and performance, making them a key component for anyone serious about their engine build.

These pistons are 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 performance engines. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal and prevent detonation. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation. The fully machined crown and forced pin oiling further enhance their ability to withstand severe duty applications.

This set includes four pistons, each with an 83.00 mm bore, a 37.00 mm compression height, and a 0.866-inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a successful build, always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
