Mahle OE NAVI 7.3L DI .010 T w/ PC Engine Set Reduced .010 CH Piston Set (Set of 8)

If you're rebuilding the engine in your 1994-2003 Ford truck or van with a 7.3L Power Stroke diesel, this Mahle OE Piston Set is a solid choice. These pistons are made to the original equipment specifications, meaning they'll perform just like the ones that came from the factory. They're specifically designed for the 7.3L direct injection diesel engine and come in a .010 inch undersize, which is crucial if your cylinders have been bored out to match this size during the rebuild process.

Mahle is one of the biggest original equipment piston manufacturers in the world, so you know you're getting a well-built part. These pistons feature compensated ring grooves that ensure the piston rings load correctly, which is key for good oil control and preventing blow-by. They also have expansion-controlled designs, allowing for tighter clearances when the engine is cold. This helps reduce engine noise, wear, and emissions, while also improving oil control. For your convenience, these pistons come with the piston rings already mounted, and the necessary pins and clips are included, saving you a step during assembly.

This set includes eight pistons, enough for a complete engine rebuild. Remember that these pistons are .010 inch undersize, so ensure your engine block has been machined to this specific size. If you're unsure about fitment for your specific Ford E-Series van or F-Series truck, it's always best to double-check the fitment guide.
