What is included in this piston set?

This Mahle OE piston set includes four pistons, pre-mounted piston rings, wrist pins, and clips. It is specifically designed for the right bank of the engine.

Why do these pistons come in an oversize (.010)?

The .010 inch oversize is common when rebuilding an engine. It allows for the cylinder walls to be honed or bored to a fresh, clean surface after wear, ensuring a proper seal with the new pistons.

Are these pistons suitable for all 6.6L Duramax engines?

This specific set is for the 2006-2010 LMM and LBZ Duramax engines with Vin code 26D, and is for the right bank only. Always confirm your engine's specific RPO codes and year range before purchasing.

Product Details

If you're rebuilding the top end of your 2006-2010 GM truck or van with a 6.6L Duramax LMM or LBZ engine, Mahle OE pistons are a solid choice. This set is specifically for the right bank (cylinders 1, 3, 5, 7) and comes with a .010 inch oversize to account for cylinder wall wear or honing. Mahle is one of the largest original equipment piston manufacturers in the world, meaning these pistons are built to the exact specifications your engine came with from the factory.

These pistons feature compensated ring grooves, which help ensure proper ring loading and effective oil control. They also incorporate expansion-controlled designs. This means they're built with tight fitting clearances, which helps reduce engine noise, wear, and emissions, all while improving oil management. Mahle makes it convenient for the engine builder by including the piston rings, wrist pins, and clips, so they're ready to install right out of the box. This set is designed to fit a range of Chevrolet and GMC trucks and vans, including models like the Silverado 2500 HD, Sierra 3500 HD, and Express 3500.

When rebuilding an engine, using OE-quality components like these Mahle pistons is crucial for long-term reliability and performance. Make sure to follow the manufacturer's installation instructions carefully, especially regarding cylinder preparation and ring gap settings for the .010 inch oversize.
