Dana 80 Posi-Traction DRW Axle Assembly 4.30 Ratio

The Zumbrota Drivetrain RAA435-2067F-P is a remanufactured complete axle assembly for the robust Dana 80 differential. This assembly is engineered with a 4.30 gear ratio and Posi-Traction limited-slip capabilities, tailored for Dual Rear Wheels (DRW) on 2002-2003 Ford F450 vehicles. Each assembly is rebuilt to stringent quality standards. Zumbrota Drivetrain meticulously inspects all components. Housing tubes are checked for OEM straightness, and housings themselves are examined for surface wear and cracks. Internally, all parts, including the ring and pinion, gears, clutches, and carrier, are fully inspected and tested. To ensure longevity and performance, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The gears are set for optimal tooth contact, precise rolling torque measured in inch-pounds, and correct backlash for quiet operation and proper lubrication. Zumbrota employs an exclusive multi-stage cleaning process that includes hydro-blasting, sandblasting, and a proprietary shot-enticed deep cleaning for internal and external parts, restoring housings to an OEM finish. It is important to note that this assembly is sold as the axle assembly only and does not include hubs, brakes, backing plates, or axle shafts. This specific unit is designed for the 2002 and 2003 model year Ford F450 equipped with the Dana 80 rear axle, dual rear wheels, and Posi-Traction.
