Mahle OE 10-16 GMC /11-16 Chevy 2500/3500 6.6L V8 Duramax 0.50mm With Rings (Set of 8)

If you're rebuilding the engine in your 2010-2016 GMC or Chevrolet truck with the 6.6L Duramax V8, Mahle OE piston rings are a solid choice. These are 0.50mm undersize rings, designed to work with pistons that have been bored out to match. Mahle is a major original equipment manufacturer, meaning these rings are built to the same standards as the ones that came on your truck from the factory. They are designed to ensure proper ring loading and effective oil control, which is crucial for engine longevity and performance.

What sets these Mahle OE rings apart is their attention to detail. They feature compensated ring grooves, which help maintain the correct pressure on the ring against the cylinder wall. This helps prevent blow-by and ensures a good seal, even as the engine heats up and components expand. Mahle also incorporates expansion-controlled designs, which means the rings are made to fit with minimal clearance. This reduces engine noise, wear, and emissions, while also contributing to better oil control. This set comes with the piston rings already mounted to the pistons, along with pins and clips, making the installation process more convenient for the engine builder.

This set includes eight piston ring sets, enough for a complete V8 engine rebuild. Mahle's reputation as one of the largest OE piston manufacturers worldwide means you're getting a well-built component that's ready for installation. Remember that these rings are 0.50mm undersize, so ensure your cylinders have been machined to the correct size to match. Please note that this part is not CARB approved and cannot be shipped to California.
