Complete Axle Assembly 3.55 Ratio Posi LSD

The Zumbrota Drivetrain RAA435-2140A is a remanufactured complete axle assembly for the Dana 60 rear axle, specifically designed for the 2001-2002 Dodge Ram 2500 4x4 models featuring a 3.55 gear ratio and Posi Limited Slip Differential (LSD). Each axle assembly undergoes a rigorous remanufacturing process. Zumbrota Drivetrain meticulously inspects all components for straightness, cracks, and surface wear. Internal parts, including ring and pinions, gears, clutches, and carriers, are fully inspected and tested. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new components to ensure reliability and longevity. The gears are inspected for optimal tooth contact patterns and set to precise backlash specifications using inch-pound measurements for proper setup and quiet operation. Axle tubes are inspected and straightened to OEM standards. Zumbrota utilizes an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peening deep cleaning process on internal and external parts. This extensive cleaning process restores cases to an OEM finish, setting a high standard for axle assembly remanufacturing. The assembly comes with a 2-year limited warranty.
