Dana 60 Remanufactured Axle Assembly 3.73 Ratio Posi Traction

The Zumbrota Drivetrain RAA435-1967B-P is a remanufactured complete axle assembly designed for the Dana 60 rear end, specifically for 1999-2004 Ford E-350 SRW (Single Rear Wheels) models equipped with full-float axles. This assembly features a 3.73 gear ratio and a 9.75-inch ring gear, incorporating Posi Traction for enhanced grip. Each Zumbrota axle assembly is rebuilt to high standards of precision and reliability. The remanufacturing process includes thorough inspection of axle tubes for straightness, cracks, and surface wear. All internal components such as ring and pinions, internal gears, clutches, and carriers are meticulously inspected and tested. As part of the rebuild, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced to ensure optimal performance and longevity. Zumbrota utilizes an exclusive cleaning process involving hydro-blast rinsing, sandblasting, and a proprietary deep cleaning method. Please note that this unit does not include hubs, brakes, backing plates, or axle shafts, which may need to be sourced separately. The precise setup and longevity are ensured by setting correct gear backlash and establishing proper rolling torque using inch-pound measurements for precise gear tooth contact patterns.
