Mahle OE GM 6.6L Duramax L w/ PCR - STD DSL .030 Piston With Rings Set (Set of 8)

Mahle is one of the largest original equipment piston manufacturers globally, known for producing parts that meet the exact specifications of your vehicle. If you're rebuilding the engine in your 2001-2005 Chevrolet Silverado 2500 HD or 3500, or your GMC Sierra 2500 HD or 3500, this Mahle OE piston and ring set is built to the same standards as the parts that originally came in your 6.6L Duramax L with PCR engine.

This set includes eight pistons, each with compensated ring grooves designed to ensure proper ring loading and effective oil control. The pistons also feature expansion-controlled designs, which allow for tight fitting clearances. This helps reduce engine noise, minimize wear, lower emissions, and further improve oil management. For your convenience, these pistons come ready for installation with the piston rings already mounted, and the necessary pins and clips are included, simplifying the engine building process.

This set is specifically sized at 0.030 inches undersize, which is crucial for engine rebuilds where cylinders may have been honed or bored. Always confirm your cylinder bore measurements before ordering to ensure you select the correct piston size for a proper fit and optimal engine performance.
