Description

The DFC Diesel Remanufactured Street Series 6.6L LML/LGH Long Block Crate Engine is a replacement engine for high-mileage GM 6.6 Duramax engines. DFC focuses on upgrading known weak points, such as adding an EDM oil pump shaft with a hardened dowel to prevent slipping and oil pressure loss. DFC checks every core before the build process and uses Rottler machining equipment for tighter and more precise tolerances than OEM specifications.
