Dana 80 Remanufactured Axle Assembly

The Zumbrota Drivetrain RAA435-2048B-P is a remanufactured complete axle assembly built around the robust Dana 80 rear end. This unit is specifically configured with a 4.10 gear ratio and a Posi Traction (limited-slip differential) for enhanced performance and traction. It is designed exclusively for Dual Rear Wheel (DRW) applications. Each axle assembly undergoes a rigorous remanufacturing process at Zumbrota Drivetrain, adhering to high standards of precision and reliability. The process includes thorough inspection of the housing for straightness, cracks, and surface wear. Internally, all components, including ring and pinions, gears, clutches, and carriers, are meticulously inspected and tested. To ensure longevity and optimal performance, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The gear setup is critical, with precise backlash and correct rolling torque established using inch-pound measurements to guarantee proper gear lubrication and quiet operation. Zumbrota employs an exclusive cleaning procedure, utilizing hydro-blasting and sandblasting on both internal and external parts, followed by a proprietary shot-peening deep cleaning process. This advanced cleaning method ensures that all housings are restored to OEM finish and meet OEM specifications for straightness. This comprehensive remanufacturing approach sets a high standard for axle assembly rebuilds. This specific assembly is intended for 2000-2004 Ford F-350 Super Duty models with Dual Rear Wheels. It does not include hubs, brakes, backing plates, or axle shafts, which are assumed to be sourced separately. The tag numbers associated with this assembly include YC35-LA, LB, and 1C34-JA.
