Dana 80 Axle Assembly 3.54 Ratio

The Zumbrota Drivetrain RAA435-1859A is a remanufactured axle assembly for Dana 80 differentials, meticulously rebuilt to OEM specifications. This unit features a 3.54 gear ratio, an 11.25-inch ring gear diameter, and a 10-bolt cover. During the remanufacturing process, all tubes are inspected and straightened to OEM standards, and housings undergo rigorous testing for surface wear and cracks. Internal components, including ring and pinion gears, internal gears, clutches, and carriers, receive a 100% inspection. Critical wear items such as bearings, seals, crush sleeves, pinion nuts, and shims are replaced entirely. The housing is then cleaned using a state-of-the-art hydro blasting and rinsing process to restore its OEM finish, and correct rolling torque is established for precision setup and longevity. This axle assembly is specifically intended for 1996-1999 Dodge Ram 3500 4x4 models. It is important to note that while some listings may mention a 3.55 ratio for the same application, this specific part (RAA435-1859A) is confirmed with a 3.54 ratio. Buyers should confirm their specific vehicle's differential requirements before purchasing. The product is built to order and has a refundable core charge of +$1,000.
