Mahle OE GM 3.5L / 3.9L 06-11 0.25MM Piston With Rings Set (Set of 6)

Mahle is one of the largest OE piston manufacturers globally, known for making parts that meet original equipment specifications. This piston and ring set is designed for GM 3.5L and 3.9L engines found in a range of vehicles from 2006 to 2011, including models like the Chevrolet Impala, Buick Lucerne, and Pontiac G6. If you're rebuilding the top end of one of these engines, this set provides the essential components to get your engine back to running smoothly.

Each piston in this set is 0.25mm undersize, which is important to note for your build. They feature compensated ring grooves to ensure the rings load correctly and maintain good oil control. The expansion-controlled design helps reduce engine noise and wear by allowing for small fitting clearances, which also contributes to better oil control and lower emissions. Mahle makes these pistons ready for installation, including the piston rings, pins, and clips, saving you time and effort during your engine build.
