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

Mahle is one of the largest OE piston manufacturers in the world, known for making parts that meet the original equipment specifications for many vehicles. This piston set is designed for GM 6.6L Duramax diesel engines from 2006-2009, specifically for the LMM and LBZ variants with a VIN code of 6 or D. This set is for the right bank only and is .020 inches undersize, meaning it's intended for engines that have been bored out to accommodate this size.

These pistons are built to OE quality standards, featuring compensated ring grooves that ensure proper ring loading and effective oil control. They also incorporate expansion-controlled designs, allowing for small fitting clearances. This helps reduce engine noise, wear, and emissions while improving overall oil control. Mahle makes these pistons ready for installation, with the piston rings already mounted. The set also includes the piston pin and clips, making the rebuild process more convenient for the engine builder.

This piston set fits a range of Chevrolet and GMC trucks and vans, including models like the Chevrolet Silverado 2500 HD and GMC Savana 3500. When rebuilding your Duramax engine, using pistons that match the original equipment specifications is crucial for reliable performance and longevity. These Mahle OE pistons offer that assurance, coming complete with rings, pins, and clips for a straightforward installation.
