Remanufactured Dana 80 Axle Assembly 3.73 Ratio

The Zumbrota Drivetrain Reman Axle Assy is a meticulously rebuilt Dana 80 axle assembly, engineered for precision and reliability. This unit features a 3.73 gear ratio, a 11.25-inch ring gear diameter, and Posi Traction for superior grip, specifically designed for Dual Rear Wheel (DRW) configurations. Every axle assembly undergoes a rigorous remanufacturing process. Zumbrota Drivetrain ensures 100% inspection of all internal parts, including the ring and pinions, internal gears, clutches, and carriers. All critical wear components, such as bearings and seals, are replaced. Gears are precisely inspected for optimal tooth contact patterns and correct rolling torque, established using inch-pound measurements to guarantee setup accuracy and longevity. The housing is inspected for straightness, cracks, and surface wear, meeting OEM standards. Zumbrota employs an exclusive multi-stage cleaning process, including hydro-blasting and sandblasting, followed by a proprietary deep cleaning procedure. This extensive cleaning restores housings to an OEM finish and ensures a clean starting point for the internal components. Correct gear backlash is meticulously set to ensure proper lubrication and quiet operation throughout the assembly's lifespan. This specific axle assembly, tagged with numbers F81A-BCF and F81A-BCG, is designed for 1999-2000 Ford F350 models. It is important to note that this assembly does not include hubs, brakes, backing plates, or axle shafts, and these components will need to be sourced separately if not already available.
