Mahle OE Ford 6.4L Diesel .75MM 2008-2010 F-250/F-350/F-450/F-550 Piston Set (Set of 8)

If you're rebuilding the engine in your 2008-2010 Ford F-250 Super Duty with the 6.4L diesel, this Mahle OE piston set is a solid choice. Mahle is a major OE piston manufacturer, meaning these pistons are built to the same standards as the ones that came from the factory. This set includes eight pistons, each measuring .75MM undersize, which is important to note if you're machining your cylinders. They come ready for installation with the piston rings already mounted, and the necessary pins and clips are included, saving you a step during the rebuild process.

These pistons feature compensated ring grooves designed to ensure proper ring loading and effective oil control. They also incorporate expansion-controlled designs, which help reduce engine noise and wear by maintaining small, consistent fitting clearances. This attention to detail not only contributes to a quieter running engine but also helps manage emissions and further improve oil control. Having pistons that fit precisely is key to a long-lasting, efficient diesel engine.

When undertaking a diesel engine rebuild, using OE-quality components like these Mahle pistons is crucial for reliability and performance. The inclusion of rings, pins, and clips in this set simplifies the assembly process for the engine builder. Remember that these pistons are not CARB approved and cannot be shipped to California.
