Wiseco Peugeot XU9J4 84.00 mm Bore 37.00 mm CH 10.00 CC Piston Set

If you're rebuilding the engine for your Peugeot XU9J4 and aiming for serious performance, Wiseco's Professional Series forged pistons are built to handle the demands of heavy to severe duty race applications. These aren't your average pistons; they're crafted with a focus on both strength and reliability when you're pushing the limits.

Each piston in this set is forged and machined right here in the USA from 2618 aluminum, a material chosen for its improved tensile strength under high stress. Wiseco machines precision ring grooves, adds anti-detonation features, and incorporates additional ring seal improvements to ensure everything stays tight and efficient. You'll also find an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and contribute to quieter operation. The fully machined crown is ready for your build, and forced pin oiling is included to keep things lubricated where it counts.

This set includes four pistons, each with an 84.00 mm bore and a 37.00 mm compression height, designed specifically for the XU9J4 engine. Remember that these pistons are not CARB approved and cannot be shipped to California. For a robust engine build that can withstand intense racing conditions, these Wiseco pistons are a solid choice.
