Mahle OE 11-16 GM 6.6L DURAMAX LML/LGH Standard Bore Piston Set (Set of 8)

If you're rebuilding the engine in your 2011-2016 GM truck or van with a 6.6L Duramax LML or LGH engine, a solid set of pistons is crucial. This set from Mahle OE offers the same quality and features you'd find from the factory, ensuring your engine runs smoothly and reliably after the rebuild. These are standard bore pistons, meaning they're designed to fit within the original cylinder wall specifications, making them a direct replacement for worn or damaged original equipment.

Mahle is one of the world's largest OE piston manufacturers, and these pistons reflect that experience. They feature compensated ring grooves, which help ensure the piston rings are loaded correctly for optimal oil control and reduced blow-by. The expansion-controlled design also means they're built with small fitting clearances. This helps reduce engine noise, minimize wear over time, and contribute to lower emissions and better oil management. For your convenience as an engine builder, these pistons come ready to install with the piston rings already mounted, and include the necessary pins and clips.

This set includes eight pistons, enough for a complete V8 engine. They are designed to fit a range of GM vehicles including Chevrolet Silverado 2500 HD, Chevrolet Express 2500, GMC Sierra 3500 HD, and GMC Savana 3500 models from 2010-2016. Please note that these pistons are not CARB approved and cannot be shipped to California.
