Build Your LML From The Crankshaft Up

A serious Duramax rebuild deserves more than a collection of replacement parts, especially when you rely on your truck to earn its keep. The DFC Diesel 661116LMLSOASBCC Speed of Air Short Block gives 2011-2016 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD owners a new engine foundation featuring a premium Callies crankshaft. That crankshaft makes this configuration especially appealing when you want quality hardware at the heart of the rotating assembly instead of taking chances with one of the most critical components in the engine. Speed of Air technology adds another performance minded element to the package, making this short block a compelling choice for an LML that sees towing, hauling, highway miles, or regular work duty. DFC also includes the internal components, oil pan, front cover with seal, and rear cover with main seal, so you are starting the project with more of the essential pieces already in place. A complete installation gasket kit and important instructions are supplied to help your installer move through the remaining assembly with the correct supporting materials on hand. When the goal is to put your Duramax back to work with a well equipped foundation underneath it, this Callies crankshaft configuration gives the rebuild a strong place to start.

A Premium Crankshaft Anchors The Rotating Assembly

The DFC Diesel 661116LMLSOASBCC is configured as a Speed of Air short block for standard automatic 2011-2016 GM trucks equipped with the 6.6L Duramax LML. Its Callies crankshaft sits at the center of the rotating assembly, where it converts piston movement into the rotational force ultimately delivered through the drivetrain. Because the crankshaft carries significant combustion and rotational loads during operation, the inclusion of a premium Callies unit is an important distinction between this assembly and the standard version of the short block. All internal short block components are included, providing the core lower engine assembly needed before the remaining LML components and systems are installed. The front cover arrives with its seal and the rear cover includes the main seal, while an oil pan is also supplied as part of the package. Additionally, DFC provides a complete gasket kit for installation along with important instructions that should be reviewed before the engine is assembled and placed into service. With a listed shipping weight of 645 pounds, proper lifting and handling equipment should be planned for when receiving and installing this substantial Duramax assembly.
