Mahle OE GM 3.5L / 3.9L 06-11 0.50MM Piston With Rings Set (Set of 6)

Mahle is one of the largest original equipment piston manufacturers globally, known for producing parts that meet the same standards as what came on your vehicle from the factory. This set of six Mahle OE pistons is specifically sized at 0.50MM undersize for GM 3.5L and 3.9L engines found in a range of vehicles from 2006 to 2011, including models like the Chevrolet Impala, Pontiac G6, and Buick Lucerne.

These pistons feature compensated ring grooves to ensure proper ring loading and effective oil control, along with expansion-controlled designs. This means they're built to maintain small fitting clearances, which helps reduce engine noise, wear, and emissions while improving overall oil management. Mahle makes installation convenient by including the pistons with the rings already mounted, and the necessary wrist pins and clips are also included, so you have everything ready for your engine rebuild.
