Dana 80 Axle Assembly 4.11 Gear Ratio

The Zumbrota Drivetrain RAA435-1766B is a remanufactured Dana 80 axle assembly, designed for 1994-1999 Dodge Ram 2500 models. This assembly features a 4.11 gear ratio and is specifically built for trucks equipped with staggered shocks. It is important to note that this assembly does not include Posi Traction. Each Zumbrota Drivetrain Axle Assembly undergoes a rigorous remanufacturing process. Internal components such as ring and pinions, gears, clutches, and carriers are thoroughly inspected and tested. All bearings and seals are replaced, and gears are meticulously inspected for optimal tooth contact patterns and correct rolling torque, ensuring precise setup and extended longevity. The assembly also features correct gear backlash settings to promote proper lubrication and quiet operation. Axle tubes are inspected to ensure they meet OEM standards for straightness. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure on both internal and external parts, followed by a proprietary shot-enticed deep cleaning process. This multi-step cleaning method sets a high standard for remanufactured axle assemblies. The assembly utilizes an 11.25-inch ring gear and has a 10-bolt cover.
