Description

The Zumbrota Drivetrain RAA435-2200 is a remanufactured axle assembly for the robust Dana 80 rear axle. This unit is meticulously rebuilt with a focus on restoring OEM specifications for optimal performance and longevity. Each assembly undergoes a comprehensive inspection process. All tubes are straightened to OEM standards, and housings are tested for cracks and surface wear. Internally, 100% of parts, including ring and pinion gears, internal gears, clutches, and carriers, are inspected. Critical wear items such as bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new components. The housing is cleaned using a state-of-the-art hydro blasting process to achieve an OEM finish, and correct rolling torque is established using inch-pound measurements for precision setup. This specific assembly is configured with a 3.55 gear ratio and a Posi limited-slip differential. It is designed exclusively for 2-wheel drive (2WD) 2000 and 2001 Dodge Ram 3500 models equipped with the Dana 80 rear axle. A refundable core charge applies to this remanufactured assembly.
