The DFC Short Block Crate Engine is a remanufactured short block built for the daily driver, diesel enthusiast and work truck user that needs to replace the engine in their 2004.5-2005 GM 6.6L Duramax LLY. Each DFC Duramax engine is built to correct known issues with the factory engine, such as installing an EDM oil pump shaft with a hardened dowel installed to prevent slipping the risk of an oil pressure loss. DFC engines are machined using Rottler equipment that allows DFC to build tighter tolerances that are more precise than OEM specification. DFC’s stringent remanufacturing standards make these engines more efficient and longer lasting. 

Engine Remanufacturing 
The DFC short block is machined with near identical weight piston and connecting rod assemblies to help you get a smoother running engine that makes less noise and is more balanced.  DFC short blocks include reinforced internals with new pistons, rings, doweled oil pump, bearings, and rods.

DFC engines are remanufactured by diesel enthusiasts for diesel enthusiasts. DFC stands behind their products with one of the industry’s leading 5 year 100,000 mile warranty.
