Dana 80 3.73 Posi Traction Axle Assembly

The Zumbrota Drivetrain RAA435-232A is a remanufactured Dana 80 axle assembly, built to exacting standards for specific Ford F350 trucks. This unit boasts a 3.73 gear ratio with Posi Traction, an 11.25-inch ring gear, and is specifically configured for dual rear wheels (DRW), cab chassis, and wide axle packages. It is a full-floating axle assembly, ensuring robust performance. The manufacturing process involves rigorous inspection of all components, including straightening tubes to OEM specifications, testing housings for surface wear and cracks, and a comprehensive 100% inspection of internal parts like gears, clutches, and carriers. Critical wear items such as bearings, seals, crush sleeves, pinion nuts, and shims are all replaced. The housings undergo a hydro blasting process to achieve an OEM finish, and precise rolling torque is established for optimal setup and extended service life. This remanufactured axle assembly is designed for 2006-2007 Ford F350 models equipped with the Dana 80 rear axle. It is crucial to note that this assembly does not include hubs, brakes, backing plates, or axle shafts, which must be sourced separately. The assembly date must be from 12/05/05 or later.
