Dana 80 Axle Assembly 11.25-Inch Ring Gear 4.10 Ratio

The Zumbrota Drivetrain RAA435-2126BL is a remanufactured axle assembly built around the robust Dana 80 differential. This unit features an 11.25-inch ring gear and a 4.10 gear ratio, making it suitable for applications requiring a specific gear split. It is configured for dual rear wheels and includes a flat flange style yoke for secure connection. Each Zumbrota axle assembly is meticulously remanufactured to ensure performance and durability. The process involves precise setup of rolling torque, verified with inch-pound measurements for optimal longevity. Housings are hydro-blasted and rinsed to achieve an OEM-like finish, while all critical wear components such as bearings and seals are replaced. Furthermore, the internal gearing, clutches, and carriers undergo a 100% inspection, and the housing itself is checked for structural integrity. Tubes are straightened to meet OEM specifications. This particular assembly is specified as "w/o Posi Traction," meaning it does not feature a limited-slip or locking differential. Additionally, it is important to note that the RAA435-2126BL does not come with hubs, brakes, backing plates, or axle shafts, which will need to be sourced separately if not already present. The product is backed by a 2-year warranty. Associated tag numbers for this unit include 2C34-UA, 2C34-UB, and 606728-2.
