Mahle OE Ford 6.4L Diesel .25MM 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, a solid set of pistons is crucial for getting your truck back on the road reliably. This set from Mahle OE is built to the original equipment specifications, meaning they'll perform just like the factory pistons did when your truck was new. They are designed to ensure proper ring loading and oil control, which helps reduce engine noise, wear, and emissions while keeping your oil consumption in check.

Mahle is one of the biggest original equipment piston manufacturers globally, so you know you're getting a well-built part. These pistons come ready for installation, with the piston rings already mounted, and include the necessary pins and clips. This convenience saves you time and hassle during your engine build. The .25MM undersize specification is important to note if you're machining your cylinders; these pistons are intended for cylinders that have been bored out by 0.25 millimeters to ensure a precise fit and optimal performance.

This set includes eight pistons, enough for a complete engine overhaul. Mahle's expansion-controlled designs are key to achieving small fitting clearances, which further contributes to a quieter running engine and improved oil control. When you're investing the time and effort into a diesel engine rebuild, using OE-quality components like these Mahle pistons is a smart choice for long-term reliability.
