Mahle OE Ford 6.4L Diesel .25MM .010 /.025MM Reduced Comp w/ Rings Piston With Rings Set (Set of 8)

Mahle is one of the biggest OE piston manufacturers globally, and they're known for making parts that meet the original equipment specifications. This set of eight pistons is built for your 2008-2010 Ford 6.4L Diesel Super Duty truck, whether it's an F-250, F-350, F-450, or F-550. These pistons are designed with reduced compression to help manage combustion pressures in your diesel engine.

What makes these pistons stand out is their OE quality construction, which means they carry over the same features you'd find from the factory. They include compensated ring grooves, which are crucial for ensuring the piston rings load correctly and maintain good oil control. Mahle also uses expansion-controlled designs, allowing for tighter clearances when the engine is cold. This helps reduce engine noise, wear, and emissions, while also improving overall oil control. To make your rebuild easier, these pistons come with the piston rings already mounted, and the necessary pins and clips are included, so they're ready to install right out of the box.

Because these are .010 inch and .025 millimeter undersize pistons, they are intended for engines that may have had some wear and require a slight increase in bore size for a proper fit. Always refer to your vehicle's service manual for specific bore measurements and installation procedures.
