Give Your LMM A Foundation Worth Building On

Pulling apart a Duramax is no small weekend project, so the short block you put back in should give you confidence in the direction of the entire build. The DFC Diesel 6607510LMMSOASBCC Speed of Air Short Block is designed for 2007.5-2010 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD trucks equipped with the 6.6L Duramax LMM. This configuration combines Speed of Air technology with a Callies crankshaft, giving owners an upgraded foundation for a truck that may spend its life towing, hauling, commuting, or working every day. Instead of piecing together the major short block components individually, you receive the internal components along with the oil pan and the covers needed to move the project forward. A complete installation gasket kit is also supplied, which helps simplify parts planning when the engine is ready to go back together. Important installation instructions provide additional guidance for the installer and help make sure the assembly is handled according to the manufacturer's requirements. For an LMM owner already committed to a substantial engine rebuild, this DFC short block brings together premium hardware and a more complete package that can make the investment feel worthwhile.

Premium Hardware Sits At The Core Of This Build

The DFC Diesel 6607510LMMSOASBCC is built around the 6.6L Duramax LMM platform and configured as a short block for standard automatic transmission applications. At the center of the rotating assembly is a Callies crankshaft, giving this particular configuration a premium component in one of the most critical areas of the engine. Speed of Air technology further distinguishes the assembly from a conventional replacement short block by incorporating specialized piston technology into the build. The assembly includes its internal engine components, providing the core rotating and reciprocating hardware needed within the short block configuration. DFC also supplies the front cover with its seal and the rear cover with the main seal, helping address important sealing points during installation. The included oil pan and complete gasket kit provide additional components required as the engine is prepared to return to service. Put together, these details make this Speed of Air assembly a well equipped starting point for rebuilding a 2007.5-2010 LMM Duramax without forcing the installer to source every major short block component separately.
