What is included in this Mahle piston set?

This set includes four pistons for the right bank of your 6.6L Duramax engine. The piston rings are pre-mounted, and the set also comes with the necessary piston pins and clips for installation.

Why are these pistons .010 undersize?

Pistons are often manufactured undersize to account for cylinder wall wear or to allow for honing and re-boring during an engine rebuild. This .010 undersize measurement means they are slightly smaller than the standard bore size, intended for cylinders that have been machined to match.

Are these pistons compatible with all 6.6L Duramax engines?

This specific set is designed for 2006-2009 LMM and LBZ Duramax engines with a VIN code of 26D, and it is for the right bank only. It's important to confirm your engine's specifications and VIN code to ensure compatibility.

Product Details

When you're diving into the heart of your 6.6L Duramax engine, specifically the LMM or LBZ models from 2006-2009 with a VIN code of 26D, Mahle OE offers a piston set designed for the right bank. This set includes four pistons, each measuring .010 inches undersize, ready to be installed. Mahle is a major OE piston manufacturer, meaning these parts are built to the same standards as what originally came in your truck.

What you get in this box are pistons that feature compensated ring grooves. This design helps ensure the piston rings are loaded correctly, which is crucial for controlling oil consumption and maintaining proper compression. They also incorporate expansion-controlled designs, allowing for tight fitting clearances. This not only helps reduce engine noise but also contributes to lower emissions and improved oil control over the life of the engine. Mahle makes it convenient for the engine builder by including the piston pins and clips, and the piston rings are already mounted, so they're ready for installation right out of the package.

This set is specifically for the right bank of your engine. It's important to confirm fitment for your specific Chevrolet or GMC 2500, 3500, or Savana/Express van from 2006 through 2010. If you're rebuilding the top end of your Duramax, these well-built pistons are a solid option to get your engine running smoothly again.
