Remanufactured Axle Assembly, 5.13 Gear Ratio

The Zumbrota Drivetrain RAA435-1958B is a remanufactured axle assembly specifically designed for the Dana 80 rear end, intended for 1996-2002 GM 3500 2WD, DRW models equipped with Wrecker Prep. This assembly features a 5.13 gear ratio, providing a significant change from stock for applications requiring increased torque or towing capability. Each axle assembly is rebuilt to stringent standards. The process begins with a thorough inspection of all tubes to ensure they are straightened to OEM specifications and that housings are tested for surface wear and cracks. Internally, all components, including the Ring & Pinion, internal gears, clutch, and carrier, are subjected to a 100% inspection. Furthermore, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts to ensure longevity and proper function. The remanufacturing process also includes a comprehensive cleaning of the housings using a state-of-the-art hydro blasting and rinsing system, restoring them to their original OEM finish. Precision setup is achieved by establishing correct rolling torque using inch-pound measurements, ensuring optimal setup and extended service life for the differential. This axle assembly is built to order and includes a refundable core charge. Zumbrota Drivetrain offers support via phone and live chat for fitment questions.
