Mahle OE 10-16 GM 6.6L Turbo Diesel Piston Set (Set of 8)

When you're rebuilding the engine in your 2010-2016 GM truck or van with the 6.6L Turbo Diesel, you get a complete set of eight Mahle OE cast pistons right out of the box. These pistons come with the piston rings already mounted, and the wrist pins and clips are included too, making the installation process much more straightforward for the engine builder. Mahle is a major OE piston manufacturer, so you know you're getting parts that meet the original equipment specifications.

These pistons are built with compensated ring grooves. This design helps ensure the rings load properly and maintain good oil control, which is crucial for engine longevity and performance, especially in a turbo diesel. They also feature an expansion-controlled design. This means they're made to have small fitting clearances when the engine is cold, which helps reduce engine noise, wear, and emissions, while also improving oil control. This attention to detail in their construction helps the engine run smoother and last longer.

This set is designed for a range of GM trucks and vans, including models like the Chevrolet Express, Silverado 2500 HD, GMC Savana, and Sierra 2500 HD. Because these are OE-quality replacements, they are made to fit and function just like the original pistons, helping to restore your engine's performance and reliability.
