Mahle OE NAVI 7.3L DI Diesel V8 T STD w/ PCR Piston With Rings Set (Set of 8)

If you're rebuilding the heart of your 7.3L Power Stroke diesel, this Mahle OE Piston With Rings Set is a solid choice. Mahle is one of the largest original equipment piston manufacturers globally, meaning these pistons are built to the same standards as what came in your Ford E-Series van or F-Series truck from the factory. This set includes eight pistons, each with its own set of rings, plus the necessary pins and clips, so you have everything ready for installation right out of the box.

These pistons feature compensated ring grooves, which help ensure the rings are loaded correctly. This is important for controlling oil consumption and maintaining good compression. They also use an expansion-controlled design, allowing for tight clearances when the engine is cold. As the engine warms up, the pistons expand just enough to achieve optimal fit, which helps reduce engine noise, wear, and emissions, all while improving oil control. This attention to detail means you're getting a well-built component designed for long-term performance and reliability.

This set is designed for a direct fit on a wide range of Ford vehicles equipped with the 7.3L DI Diesel V8 engine, including models like the Ford F-250 Super Duty, Ford Excursion, and Ford E-350 Econoline. Having the piston rings already mounted saves you a critical step during the rebuild process, making your job a bit smoother. Just be aware that these are not CARB approved and cannot be shipped to California.
