Reman Axle Assembly, 5.38 Ratio, Dana 80, Dual Rear Wheel

The Zumbrota Drivetrain Reman Axle Assembly is a fully remanufactured unit designed to replace the original axle assembly for specific Dana 80 differentials. This particular assembly boasts a 5.38 gear ratio, making it suitable for applications requiring enhanced torque multiplication, such as heavy-duty towing or hauling with dual rear wheels. The remanufacturing process at Zumbrota Drivetrain is extensive. It includes rigorous inspection and straightening of all tubes to meet OEM specifications, along with thorough testing of housings for any surface wear or cracks. Every internal component, including ring and pinion gears, internal gears, clutches, and carriers, is subjected to a 100% inspection. Crucially, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The housings are then cleaned using a state-of-the-art hydro blasting and rinsing process to restore them to an OEM finish. Finally, the correct rolling torque is established using precise inch-pound measurements to ensure optimal setup and longevity. This assembly is specifically noted for the Dana 80, 11.25-inch ring gear, and dual rear wheels. Technical notes confirm the 5.38 ratio and mention that the tag numbers YC35-RA and TA are applicable. It features Posi Traction for improved grip and performance. However, it is important to note that this assembly does not include hubs, brakes, backing plates, or axle shafts, which must be sourced separately if needed.
