Mahle OE 10-16 GMC /11-16 Chevy 2500/3500 6.6L V8 Duramax 0.25mm w/ Rings (Set of 8)

If you're rebuilding the engine in your 2010-2016 Chevrolet Express, GMC Savana, or Silverado/Sierra 2500/3500 HD with the 6.6L Duramax V8, getting the right piston rings is crucial for proper compression and oil control. These Mahle OE piston rings are designed to meet the original equipment specifications for your truck, ensuring a solid fit and reliable performance. They come pre-installed on the pistons, saving you a significant step during the rebuild process.

Mahle is one of the world's largest OE piston manufacturers, and these rings reflect that expertise. They feature compensated ring grooves, which help ensure the rings load correctly and maintain good oil control. The expansion-controlled design also means they have small fitting clearances, which helps reduce engine noise, wear, and emissions, all while improving oil management. This set includes eight pistons, each with the rings already mounted, along with the necessary wrist pins and clips, making them ready for installation right out of the box. The 0.25mm undersize specification is important to note if you are re-boring your cylinders to a specific size.

Having these rings installed by Mahle means you can focus on other aspects of your engine build. They are a well-built component from a trusted OE supplier, designed to get your Duramax engine back to its intended performance. Remember that these parts cannot ship to California due to Proposition 65 regulations.
