Dana 80 Rear Axle Assembly 3.73 Ratio Posi Traction Dual

The Zumbrota Drivetrain RAA435-2047A-P is a remanufactured Dana 80 axle assembly built to high standards of precision and reliability. It is designed for the rear axle of specific vehicles and features a 3.73 gear ratio with Posi Traction for improved grip, a dual rear wheel setup, and an 11.25-inch ring gear diameter. Each axle assembly undergoes a rigorous remanufacturing process. Zumbrota Drivetrain meticulously inspects internal components such as ring and pinions, internal gears, clutches, and carriers for any signs of wear or damage. All bearings and seals are replaced with new ones. The gears are carefully inspected for optimal tooth contact patterns and set to precise backlash specifications, measured in inch-pounds, to ensure proper gear lubrication and quiet operation, contributing to extended longevity. Zumbrota employs an exclusive cleaning procedure involving hydro-blasting, sandblasting, and a proprietary shot-peening deep cleaning process for both internal and external parts. This thorough cleaning process sets a high standard for axle assembly remanufacturing. The axle tubes are also inspected to ensure they meet OEM standards for straightness. This specific axle assembly is designed for 1999-2000 Ford F-350 Dual Rear Wheel (DRW) models. It does not include hubs, brakes, backing plates, or axle shafts, which may need to be sourced separately. Some listings also indicate potential fitment for 1989-2002 Dodge vehicles with a 5.9L Cummins engine, though verification is recommended.
