Especially remanufactured to support up to 550 horsepower, the DFC Diesel Remanufactured Tow/Haul Series Long Block Crate Engine is a great replacement engine for your 2011-2019 Ford 6.7L Powerstroke. Each DFC engine is remanufactured from quality parts to meet the most strict guidelines. Each DFC engine is machined using advanced Rottler equipment and has important upgrades that help your engine maintain its reliability and performance. Constructed to tolerances that are tighter than the factory specifications, the Tow/Haul Series is more efficient and is a longer lasting engine!


Engine Remanufacturing

DFC engines are usually matched with near identical weight piston and connecting rod assemblies. This gives you 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

During the remanufacturing process, DFC upgrades the Tow/Haul Series engine to give you a better performing and longer lasting engine. Each long block gets ARP 2000 Series Head Studs, ceramic coated piston crowns and dry film coated skirts, DFC HD push rods, and pinned main bearings.


Cylinder Head

Each 6.7L Powerstroke Tow/Haul Series engine comes standard with O-ringed cylinder heads. DFC replaces each valve guide with a new cast guide in every cylinder head. Instead of just giving the burnt 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 machines each head to remove the factory hardened seat material then installs new SBI valve seats to help eliminate premature cracking.



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