Description

The DFC Street Series Engines represent a key component within DFC’s premier product lineup. Tailored for work truck owners, daily drivers, and diesel enthusiasts seeking a top-notch rebuild, this series offers a compelling option for those who prefer not to replace their entire truck. Throughout the meticulous remanufacturing process, DFC incorporates enhancements to bolster your engine’s durability and reliability, particularly in applications requiring increased horsepower. Utilizing cutting-edge Rottler equipment, each engine undergoes construction with precision, surpassing OEM specifications for tighter tolerances. The result is an engine that is not only more efficient but also boasts an extended lifespan.

Engine Remanufacturing 

During the build, DFC addresses known leak areas and remedies these issues, such as adding a bead of silicone on the main cap plate to eliminate potential for leaks down the road. DFC engines are typically matched with near identical weight piston and connecting rod assemblies. As a result, you get a smoother running engine that feels more balanced with less noise. This remanufactured Long Block includes new pistons, rings, bearings, and seals. 

Cylinder Head 

Unlike some others in the remanufacturing industry that re-use wearing items like valve guides, DFC replaces each one with new cast guides in every cylinder head. They don’t stop there; instead of just a re-grinding high-mileage valves, 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 and then installs new SBI valve seats to help eliminate premature cracking, giving you a more durable cylinder head. 

Upgraded Fasteners 

DFC Street Series engines come standard with OptiTorque or ARP 2000 Series Head Studs (depending on availability) to give you peace of mind that your new engine won’t fail like an OE Ford engine due to head gasket issues. Not only does DFC use Head Studs to keep the heads in place they also replace the factory connecting rod bolts with upgraded fasteners when assembling the bottom end of your 6.0 Powerstroke engine to ensure that you have an engine that is more dependable than the original.
