Mahle OE NAVI 7.3L IDI Turbo DSL V8 T .040 w/ PC Piston With Rings Set (Set of 8)

This Mahle OE piston set is built for your 1994 Ford F-250, F-350, F-59 Commercial Stripped Chassis, or F-Super Duty equipped with the 7.3L IDI Turbo Diesel V8 engine. These pistons are 0.040 inch oversize, meaning they are designed to replace worn cylinders that have been bored out to accommodate this larger size. Mahle is a major OE piston manufacturer, and these pistons carry that same quality and design that came from the factory.

What sets these Mahle pistons apart is their attention to detail for optimal engine performance and longevity. They feature compensated ring grooves, which help ensure the piston rings are properly loaded and maintain excellent oil control. This is crucial for preventing oil from entering the combustion chamber and for maintaining good compression. Additionally, these pistons have an expansion-controlled design. This means they are built to maintain very small, precise clearances within the cylinder bore, even as the engine heats up. This reduces engine noise, minimizes wear over time, and helps keep emissions in check while also contributing to better oil control.

This set comes complete with the piston rings already mounted, along with the necessary wrist pins and clips. This makes the installation process more convenient for the engine builder, as these critical components are ready to go. Mahle OE pistons are known for their quality and are a solid option when rebuilding your diesel engine.
