Product Details

When you're rebuilding the top end of your 2006-2010 GM truck with a 6.6L Duramax engine, specifically LMM or LBZ models with VIN code 26D, Mahle OE pistons offer a well-built solution. This set includes four pistons, each with their matched rings already mounted, along with the necessary pins and clips. This means you get everything you need for the left bank of your engine in one convenient package, ready for installation right out of the box.

Mahle is a major OE piston manufacturer, and these pistons carry that same quality. They feature compensated ring grooves designed to ensure proper ring loading and effective oil control, which helps reduce blow-by and keep oil consumption in check. The expansion-controlled design also means they're made to fit with minimal clearance, helping to quiet engine noise, reduce wear, and lower emissions. These are built to perform just like the original equipment, providing a solid foundation for your engine rebuild.

This set is specifically for the left bank of your engine. If you're undertaking a complete engine overhaul, be sure to check the manufacturer's specifications for any additional components or hardware you might need for your specific build. Mahle's reputation as a leading OE supplier means you can trust these pistons to meet the demanding requirements of your Duramax engine.
