DFC Diesel Remanufactured Street Series Long Block Crate Engine

The DFC Diesel Remanufactured Street Series Long Block Crate Engine is a cost effective option to a factory replacement engine in your 2004.5-2007 Dodge 5.9L Diesel (Automatic & Manual). Built for the daily driver, work truck owner, and diesel enthusiast that wants a quality build, the Street Series Long Block is constructed to meet strict guidelines. DFC makes crucial upgrades that help your engine maintain its high performance capability with no drawbacks to reliability. Machined using advanced Rottler machining equipment, you can be sure your engine is built to tolerances that are tighter than the factory specs for an efficient and long lasting engine!

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.

Each 5.9L Diesel Street Series engine comes standard with ARP or OptiTorque head studs (depending on availability). The Street Series engine features improved gasket sealing methods in common leakage areas and prevents piston failures caused by faulty injectors with increased piston cooling.

DFC replaces each valve guide with a new cast guide in every cylinder head. Instead of just giving old valves a re-grind, 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 (Non-Commercial). 

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.
