What is included in this Mahle OE piston set?

This set includes eight Mahle OE pistons, each measuring 0.25mm undersize. It also comes with the necessary piston rings, pins, and clips already mounted for your convenience.

Why are these pistons 0.25mm undersize?

The 0.25mm undersize specification indicates these pistons are slightly smaller than the standard bore size. This is common for engine rebuilds, especially if the cylinders need to be honed or bored to a slightly larger size to ensure a proper fit and seal.

Are these pistons compatible with all 6.4L diesel engines?

This specific Mahle OE piston set is designed for the Navistar MaxxForce 7 6.4L diesel engine found in the 2008-2010 Ford F-250 and F-350 Super Duty trucks. Always verify fitment for your specific vehicle's engine.

Product Details

When you're rebuilding the engine in your 2008-2010 Ford F-250 Super Duty with the Navistar MaxxForce 7 6.4L diesel, getting the right pistons is crucial. This set from Mahle OE gives you eight pistons, each measuring 0.25mm undersize, along with the necessary piston rings, pins, and clips. Mahle is a major OE piston manufacturer, meaning these parts are built to the same standards as what originally came in your truck.

These pistons feature compensated ring grooves, which help ensure the rings seat properly and maintain good oil control. They also use an expansion-controlled design. This means they're built to have tight clearances when the engine is cold, which helps reduce noise, wear, and emissions once the engine warms up and the parts expand. Having the rings, pins, and clips already mounted and included in the set simplifies the assembly process for you, saving time and hassle during your engine build.

This set is designed as a direct replacement for your specific F-250 or F-350 Super Duty models from 2008 to 2010. Remember that these pistons are not CARB approved and cannot be shipped to California.
