What does 'right bank only' mean for this piston set?

This means the set contains pistons specifically designed for one side of the V-engine. For your 6.6L Duramax, this set is intended for the passenger side bank of cylinders. You will need a separate set if you are replacing pistons on the driver's side.

Are the piston rings included and pre-installed?

Yes, this Mahle OE piston set comes with the piston rings already mounted onto the pistons. The set also includes the necessary piston pins and clips, so they are ready for installation right out of the box.

What is the benefit of 'expansion controlled designs' in these pistons?

Expansion controlled designs allow the pistons to maintain a precise fit within the cylinder bore across a range of operating temperatures. This helps to reduce engine noise, minimize wear, control emissions, and improve overall oil management.

Product Details

If you're rebuilding the top end of your 6.6L Duramax diesel, specifically the right bank of an LMM or LBZ engine from 2006-2010 (VIN code 26D), this Mahle OE Piston With Rings Set is a solid choice. Mahle is a major OE supplier for many manufacturers, so you're getting pistons that meet the original equipment specifications for your truck. This set includes four pistons, each with their rings already mounted, along with the necessary pins and clips, making the installation process more straightforward for the engine builder.

These pistons are built with compensated ring grooves, which helps ensure the rings are properly loaded and maintain good oil control. They also feature an expansion-controlled design. This means the pistons are made to fit with minimal clearance, which helps reduce engine noise, wear, and emissions while also improving oil management. Because Mahle is one of the largest OE piston manufacturers globally, you can trust that these pistons are well-made and designed to perform like the originals.

This set is specifically for the right bank of your engine. It's important to confirm your vehicle's VIN code to ensure it matches the 26D specification for these years. While these pistons are designed for optimal performance and durability, please note they are not CARB approved and cannot be shipped to California.
