Dana 80 Rear Axle Assembly 4.10 Ratio

The Zumbrota Drivetrain RAA435-1823 is a remanufactured axle assembly specifically engineered for the Dana 80 rear differential. This unit boasts a 4.10 gear ratio and an 11.25-inch ring gear diameter, designed to meet the demands of specific heavy-duty applications. Each Zumbrota Drivetrain Axle Assembly is meticulously rebuilt to exacting quality standards, ensuring precision and reliability. The remanufacturing process involves thorough inspection of all components, including the housing for straightness, cracks, and surface wear. Internal parts such as ring and pinions, gears, clutches, and carriers are fully inspected and tested. All bearings and seals are replaced as a standard procedure. The gears are carefully examined for optimal tooth contact patterns and set to correct rolling torque using precise inch-pound measurements to ensure proper setup and longevity. Specific to this assembly, it is designed for 1994-1995 Dodge/GMC Ram 3500 2WD models equipped with staggered shocks. It features a 10-bolt differential cover, a full-floating axle type, and comes with the cover included. It is important to note that this assembly is explicitly for 2WD models and excludes cab chassis configurations. It also does not include Posi Traction. Fluid is not included with this axle assembly and must be purchased separately. Zumbrota employs a rigorous cleaning process, including an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peening deep cleaning. This dedication to detail in remanufacturing sets a high standard for axle assembly longevity and performance.
