Mahle OE GM 6.6L Duramax 06-09 LMM LBZ Vin 26D .020 Left Bank Only Piston Set (Set of 4)

If you're rebuilding the top end of your 2006-2010 GM 6.6L Duramax LMM or LBZ diesel, a quality piston set is crucial. These Mahle OE pistons are specifically for the left bank and come at a .020 inch undersize, ready to be installed in your engine block. Mahle is one of the largest original equipment piston manufacturers globally, meaning these parts meet the same standards as what came from the factory.

These pistons are built with compensated ring grooves to ensure proper ring loading and effective oil control. They also feature expansion-controlled designs, allowing for tight fitting clearances. This design helps reduce engine noise, minimize wear, lower emissions, and further improve oil management. For your convenience, Mahle includes the piston rings, pins, and clips, so they are ready for installation right out of the box. This makes the rebuilding process smoother, letting you focus on getting your engine back to peak performance.

This set includes four pistons, specifically for the left bank of your engine. Always verify your engine's VIN code and specific requirements before ordering to ensure you get the correct parts for your rebuild.
