Mahle OE Navistar MaxxForce 7 6.4L Diesel .50MM Piston Set (Set of 8)

Mahle is one of the largest original equipment piston manufacturers globally, known for producing parts that meet the same standards as what came on your vehicle from the factory. If you're rebuilding the engine in your 2008-2010 Ford F-250 Super Duty with the Navistar MaxxForce 7 6.4L diesel, this set of eight Mahle OE pistons, sized at .50MM undersize, is designed to get your engine back to its intended performance.

These pistons are built with compensated ring grooves, which help ensure the piston rings are loaded correctly. This is important for both controlling oil consumption and maintaining proper combustion pressure. They also feature an expansion-controlled design. This means they're made to have tight clearances when the engine is cold, which helps reduce engine noise, wear, and emissions as the engine warms up and the components expand. Mahle makes it convenient for engine builders by including the piston rings, pins, and clips, so these pistons are ready to be installed right out of the box.

This set includes eight pistons, all sized at .50MM undersize, which is a common requirement for engine rebuilds where the cylinder walls may have been honed or machined to a slightly larger diameter. Please note that these pistons are not CARB approved and cannot be shipped to California.
