1994-2018 5.9L 6.7L Cummins 12V 24V

The DFC Diesel Remanufactured Street Series Long Block Crate Engine is an expertly remanufactured replacement engine for your 1994-2018 Dodge 5.9L or 6.7L Cummins (Manual & Automatic). 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”. As a result, you get a reliable and durable engine that is guaranteed to perform. Built for the daily driver, the Street Series Long Block has crucial upgrades that help your engine maintain its high-performance capability without affecting reliability. Machined using advanced Rottler machining equipment, you can be sure your engine is built to tolerances that are more precise than the factory specs for an efficient and long-lasting engine!

Engine Remanufacturing

DFC engines are usually matched with near-identical weight piston and connecting rod assemblies. As a result, you get a smoother running engine that creates less noise and feels more balanced. This remanufactured Long Block includes new pistons, rings, bearings, and seals.

Engine Upgrades

Each Cummins Street Series engine comes standard with an O-ringed cylinder head. The Street Series engine features improved gasket sealing methods in common leakage areas and has a multi-layer steel head gasket.

Cylinder Head

DFC replaces each valve guide with a new cast guide in every cylinder head. Instead of just re-grinding old valves, DFC installs all new valves from high-quality sources like MAHLE or SBI. 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.


DFC engines are remanufactured by diesel enthusiasts and are built for diesel enthusiasts. To show their pride, DFC offers one of the most comprehensive warranties in the industry. Each DFC Street Series Long Block Engine comes standard with a 5-year, 100,000 mile warranty.

The DFC Long Block has all rockers and pushrods preset to factory specifications and includes a remanufactured cylinder head, internal components, front & rear cover, oil pan, and the complete gasket kit for long block installation.
