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

Mahle pistons are built to the same specifications as the original equipment your GM vehicle came with. These pistons feature compensated ring grooves, a design choice that helps ensure proper ring loading and keeps oil where it belongs, which is crucial for maintaining good oil control and reducing emissions. They also incorporate expansion-controlled designs, allowing for tighter fitting clearances. This not only helps reduce engine noise and wear but also contributes to better emissions control and improved oil management over the life of the engine.

This set includes six pistons, each with their piston rings already mounted, along with the necessary wrist pins and clips. This means they are ready for installation right out of the box, saving you time and effort during your engine rebuild. Mahle is one of the largest original equipment piston manufacturers globally, so you're getting a well-built part that meets stringent OE standards. This set is designed to fit a range of GM vehicles equipped with the 3.5L or 3.9L engine, including models like the Chevrolet Impala, Pontiac G6, and Saturn Aura.

When undertaking an engine rebuild on your 2006-2011 GM vehicle with a 3.5L or 3.9L engine, using OE-quality pistons like these from Mahle is a smart move. They are designed to restore your engine's performance and efficiency to its original specifications. Please note that this part is not CARB approved and cannot be shipped to California.
