DFC Diesel Rebuilders

The 6.6L Duramax is known for running smoothly and pulling hard. Our reman builds take it a step further, replacing weak components with stronger upgrades that keep you running longer. When your work depends on your truck, this is the kind of reliability you can’t put a price on.

Looking for a way to get more out of your diesel engine? The Speed of Air upgrade helps your engine run cleaner and more efficiently, which means better fuel mileage and quicker throttle response. Many drivers notice their truck feels smoother and stronger, especially after the first 1,000 km. If you want to save money and boost performance, check out the only piston that pays for itself.

Not all engines are rebuilt the same way. A rebuilt engine usually only replaces broken parts, but a remanufactured engine is completely taken apart and rebuilt from the ground up to factory standards. At DFC Diesel, our reman engines are tested, measured, and assembled using brand-new parts where needed, so you get something that feels and performs like new.
