Dana 60 Rear Axle Assembly 4.09 Ratio Posi Traction

The Zumbrota Drivetrain RAA435-1966D-P is a remanufactured axle assembly specifically designed for Dana 60 differentials. This unit is built to the highest quality standards, ensuring precision and reliability. It features a 4.09 gear ratio, a substantial 9.75-inch ring gear, and is configured with rear disc brakes for improved stopping power. The Posi Traction limited-slip differential provides enhanced traction and performance. Each axle assembly is meticulously inspected. The tubes are checked for straightness to OEM specifications, and housings are tested for surface wear and cracks. All internal components, including the ring & pinion, internal gears, clutches, and carrier, undergo a 100% inspection. To guarantee longevity and precise setup, Zumbrota Drivetrain replaces all bearings, seals, crush sleeves, pinion nuts, and shims. The correct rolling torque is established using inch-pound measurements, and proper gear backlash is set for optimal lubrication and quiet operation. Zumbrota employs an advanced cleaning process, utilizing a state-of-the-art hydro blasting and rinsing procedure for both internal and external parts. This process restores the housings to an OEM finish, setting a high standard for remanufactured axle assemblies. This particular assembly does not include hubs, brakes, backing plates, or axle shafts.
