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

Mahle is one of the largest original equipment piston manufacturers globally, known for producing parts that meet the exact specifications of vehicle manufacturers. This piston and ring set is designed for the GM 6.6L Duramax engine, specifically for the LMM and LBZ models from 2006-2009 with a VIN code of 26D. This set is for the right bank of cylinders and is machined 0.030 inches oversize, which is crucial for rebuilding an engine where the cylinders may have been bored out to correct wear or damage.

These pistons come with compensated ring grooves to ensure proper ring loading and effective oil control, helping to prevent blow-by and oil consumption. The expansion-controlled design allows for minimal clearance between the piston and cylinder wall, which reduces engine noise, wear, and emissions while improving overall oil management. Mahle OE pistons are ready for installation right out of the box, including the piston pin and clips, making the assembly process more convenient for the engine builder. This attention to detail helps ensure a solid rebuild that performs like the original.

This set includes four pistons and their corresponding rings, specifically for the right bank of your 6.6L Duramax engine. It's important to note that this part is not CARB approved and cannot be shipped to California. When rebuilding your Duramax, using OE-quality components like this Mahle set is key to achieving reliable performance and longevity.
