Mahle OE GMC Trk6.6L V8 Duramax Diesel 2001-2005 Right Hand Piston .010 Piston Set (Set of 4)

If you're rebuilding the top end of your 2001-2005 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD with the 6.6L V8 Duramax diesel, this Mahle OE right-hand piston set is a solid choice. These pistons are .010 inch undersize, meaning they are designed to fit slightly smaller bores, which is common during engine rebuilds when cylinders might be honed to a specific size. Mahle is a major OE piston manufacturer, so you're getting parts that meet the original equipment specifications for your truck.

What sets these Mahle pistons apart is their attention to detail for proper engine function. They feature compensated ring grooves, which help ensure the piston rings are loaded correctly. This is crucial for good oil control and preventing blow-by. The pistons also have expansion-controlled designs, allowing for tight fitting clearances. This not only helps reduce engine noise but also contributes to lower wear, better emissions control, and improved oil management over time. Mahle often includes the piston pin and clips, and these sets come with the rings already mounted, making the installation process more straightforward for the engine builder.

This set includes four right-hand pistons, designed to work with your Duramax diesel engine. Remember that these are not CARB approved and cannot be shipped to California. Always refer to your vehicle's service manual for specific installation procedures and torque specifications.
