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.
