Dana 80 Axle Assembly 3.54 Posi Limited Slip Differential

The Zumbrota Drivetrain RAA435-1766A-P is a remanufactured Dana 80 complete axle assembly, featuring a 3.54 gear ratio and a Posi Limited Slip Differential (LSD). This assembly is built to high standards of precision and reliability. During the remanufacturing process, each axle assembly is meticulously inspected for straightness, cracks, and surface wear. All internal components, such as ring and pinions, internal gears, clutches, and carriers, are fully inspected and tested. Zumbrota replaces all bearings, seals, crush sleeves, pinion nuts, and shims. The gears are carefully set to achieve optimal tooth contact patterns and correct rolling torque, measured in inch-pounds, for precise setup and longevity. Proper gear backlash is set to ensure adequate gear lubrication and quiet operation. Axle tubes are verified to meet OEM specifications for straightness. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure on both internal and external parts, followed by a proprietary shot-peening deep cleaning process, setting a high standard for axle assembly remanufacturing. This axle assembly is compatible with 1994-1999 Dodge Ram 2500 models equipped with Staggered Shocks and the Posi-Traction feature. It is specified for RWD models with a 10-bolt differential cover. Some sources also list fitment for 1998.5-2018 Dodge Ram with 5.9L/6.7L Cummins Engines.
