Wiseco Peugeot XU10J4 86.50 mm Bore 39.16 mm CH -14.00 CC Piston Set

If you're building a performance Peugeot XU10J4 engine, this set of forged pistons from Wiseco is designed to handle the demands of serious racing. These pistons feature an 86.50 mm bore and a 39.16 mm compression height, with a dish volume of -14.00 CC, which is crucial for setting up your engine's compression ratio. They are built for heavy to severe duty applications, meaning they're made to withstand the stress of high-performance use.

Wiseco crafts these pistons in the USA from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for racing conditions. You'll find precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal. They also come with an ArmorGlide skirt coating, which helps reduce friction and resist seizure, while also contributing to quieter operation. The fully machined crown ensures accuracy, and forced pin oiling helps keep the wrist pin lubricated under high loads.

This set includes four pistons, along with premium rings. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a robust engine build that prioritizes durability and performance under extreme conditions, this Wiseco piston set is a solid option.
