DFC Diesel Remanufactured Street Series 6.6 LML/LGH Long Block Crate Engine

The DFC Diesel Remanufactured Street Series 6.6 LML/LGH Long Block Crate Engine is a perfect replacement engine for your high-mileage GM 6.6 Duramax. DFC commits to their high standards by making crucial improvements during the remanufacturing process to maintain reliability, even with applications that have addition horsepower over stock. DFC focuses on upgrading the Duramax's known weak points from the factory, such as adding an EDM oil pump shaft with a hardened dowel to prevent slipping and the risk of oil pressure loss. DFC checks every core before the build process and uses Rottler machining equipment that allows for tolerances that are tighter and more precise than OEM specification. DFC chooses only the best cores and rejects any components that require considerable “restoring” as a way to maintain the highest standards possible.
