DFC Diesel Remanufactured 6.6 LLY Short Block Crate Engine

DFC’S remanufactured Short Block Crate engine is an outstanding option for any daily driver, diesel enthusiast, or work truck that needs to replace the engine in their 2004.5-2005 GM 6.6L Duramax LLY Kodiak/Topkick. To ensure that every engine is built to the same high quality standards, DFC uses only the best cores and rejects components that require considerable "restoring". Every Duramax engine that DFC rebuilds come with an EDM oil pump shaft with a hardened dowel installed to prevent slipping and the risk of oil pressure loss. DFC uses state of the art Rottler machining equipment that allows DFC to build tighter and more precise tolerances than OEM specifications. DFC’s strict remanufacturing process makes sure their engines will last for years to come.

The DFC short block is machined with almost 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.

Complete short block with the front cover and seal, rear cover with main seal, all new internal components and complete gasket kit for installation. Oil pan and rear engine housing are not included. These components are specific to the Kodiak/Topkick models and you must re-use your existing components.

Oil Cooler - highly recommended and mandatory if your past engine had a bearing failure.

Injectors - highly recommended especially on higher model engines or engines with contaminated fuel.

Turbocharger - recommended if mileage over 125K, mandatory if shaft play, or if engine was dusted.

Water Pump - highly recommended if engine has over 125K. 

Evans Waterless Coolant - recommended upgrade to prevent corrosion and boilover. 

 

Oil pan and rear engine housing are not included. These components are specific to the Kodiak/Topkick models and you must re-use your existing components.

The specific brand of each component may change due to part availability at the time of each build. Parts are chosen at the discretion of DFC and cannot be specially requested. DFC uses only the best components sourced from multiple brands during the remanufacturing process.

Note: $500 Crate charge is included in core charge total. Engine shipping crate must be returned with core engine to receive full core credit.
