DFC Diesel Remanufactured 6.6 LMM Long Block Crate Engine

The DFC Remanufactured Long Block Crate Engine is built for the daily driver, diesel enthusiast and work tuck that needs to replace the damaged engine in their 2007.5-2010 GM 6.6L Duramax LMM. During the remanufacturing process, DFC focuses on improving OEM weak points to maintain reliability and durability. One of these improvements is that every Duramax remanufactured engine comes with an EDM oil pump shaft with a hardened dowel installed to prevent slipping the risk of oil pressure loss. DFC uses Rottler machining equipment that machines so precise it allows tolerances to be tighter than OEM specification. Each core is carefully inspected, allowing DFC to reject any components that require considerable restoring. DFC takes pride in building their remanufactured engines to the most stringent guidelines, ensuring a durable and reliable engine.

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.

Unlike some other engine builders in the industry that re-use wearing items like valves and valves guides, DFC installs all new valves from high quality sources like MAHLE or SBI and replaces each valve guide with a new cast guide in every cylinder head. To address common cracking areas in the cylinder head, DFC also machines each head to remove the factory hardened seat material. DFC then installs new SBI valve seats to help eliminate premature cracking, giving you a more durable cylinder head.

Complete short block with the front cover and seal, rear cover with main seal, oil pan, all new internal components, cylinder heads with all rockers and pushrods installed, doweled oil pump gear, woodruff keyed cam shaft and complete gasket kit for installation.

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. 

 

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.
