DFC Remanufacted 07.5-10 Duramax 6.6 LMM Long Block Engine

700.00 (Fixed shipping cost)

Product Description

5 Year/100K Mile Warranty -Our street series of engines are DFC’s flagship product. Built for work trucks, daily drivers and the diesel enthusiast in mind these engines are a vast improvement from stock as they contain important upgrades to common problem areas. With the majority of Dodge, Ford and Chevy truck owners having some form or another of aftermarket upgrades done, DFC has remanufactured all of our engines with the highest quality duramax diesel parts in Edmonton. Your engine will perform flawlessly with added horsepower and still backed with one of the industry leading warranties in North America.


Oil Pump

All DFC Duramax engines feature an EDM doweled oil pump shaft with a hardened dowel installed locating the gear to the oil pump shaft preventing slipping and the subsequent oil pressure loss.


Our Rottler equipment allows us to remanufacture the Duramax engine’s to tighter than OEM specifications resulting in a longer lasting more efficient engine assembly.

 Head Gasket Sealing

Some model years of Duramax engines are more susceptible to premature head gasket failure. To reduce the chance of this all DFC long blocks come with new head bolts, revised torque sequences and digitally recorded torque values to ensure reliability.

 Core Criteria

Ensuring every engine is built to the same high quality standards as the next DFC is very strict on what is remanufactured rejecting components that require considerable “restoring” to acceptable specifications.

 Valve Springs

Instead of just testing old springs and reusing like most remanufactures DFC installs brand new SBI valve springs that are still tested for proper spring pressure on every cylinder head we rebuild.


DFC installs new valves from MAHLE/Clevite or SBI in every cylinder head we remanufacture. Most companies will re-grind and install used again.

 Cast Guides

Common industry practice is to check guide clearance and if within specification, not replace. DFC considers this practice unacceptable and installs new cast SBI guides in every cylinder head we remanufacture.

 Weighed Rotating Assemblies

Our production engines are typically matched with near identical weight piston and connecting rod assemblies giving our customers a smoother running and quieter engine.

 Torque Specs

These engines use many torque to yield fasteners that require bolt “stretch” to maintain adequate clamp loads. In addition to not just following the OEM procedures for tightening sequence our assembly technicians record the achieved torque load through use of digital torque wrenches ensuring no fastener will come loose over time.


Our comprehensive warranty is one of the best in the industry giving you 5 years and 100,000 miles of coverage and is provided 100% by DFC and not a third party like some manufacturers. Some remanufacturers may offer similar lengths of warranty coverage, some are parts only and some offer unlimited mileage for their duration. With these in mind we at DFC like to be as fully transparent as possible with all of our valued customers which is why we clearly post our warranty online for anyone to read. As other companies may not post their warranty online or when asked a question about theirs, give generic replies, we wanted to give our customers some questions to ask when they are shopping around for an engine so they can be better informed on their final decision. We would also like to give some insight on why there are so many different warranties out there, as it will show you what there criteria may be like for their rebuilding process.

*** Please Allow 2-5 business days for engine to be built.  Delivery is approx 5-7 business days after it ships ***


There is a separate core charge of $2000 that will be charged separately from the cost of the engine.  This charge must be paid before the engine ships.  We will run the same card you used to pay for the engine purchase for the core.  When the core is returned and inspected, the core charge will be returned less any charges for portions of the core engine that are unusable do to damage.
