Mahle OE GM 6.6L Duramax 06-09 LMM LBZ Vin 26D .030 Left Bank Only Piston With Rings Set (Set of 4)

If you're rebuilding the top end of your 2006-2010 GM 6.6L Duramax LMM or LBZ diesel, getting the right pistons is crucial for restoring performance and reliability. This set of four Mahle OE pistons is specifically for the left bank and comes in a .030 inch undersize, ready to be installed in engines that have been bored out to match. Mahle is a leading original equipment manufacturer for pistons worldwide, meaning these parts are built to the exact specifications your engine was designed with.

These pistons feature compensated ring grooves, which help ensure the piston rings are properly loaded and maintain excellent oil control. They also use expansion-controlled designs, allowing for tight fitting clearances. This reduces engine noise, lowers emissions, and contributes to better oil management over time. Mahle makes it convenient for engine builders by including the piston rings, wrist pins, and clips already mounted and ready for installation, saving you time and hassle during your rebuild.

This set is designed for the left bank (cylinders 1, 3, 5, 7) of your 6.6L Duramax engine. Remember to verify your engine's VIN code and bore size to ensure this .030 inch undersize set is the correct fit for your specific rebuild project. If you're unsure about the exact size needed after machining, it's always best to measure your cylinders before ordering.
