Dana 80 4.30 Gear Ratio Axle Assembly

The Zumbrota Drivetrain RAA435-2067C-P is a remanufactured Dana 80 axle assembly designed for heavy-duty applications. It features a 4.30 gear ratio, an 11.25-inch ring gear, and is configured for dual rear wheels. This assembly is built to exacting standards, ensuring precision and reliability for your drivetrain. During the remanufacturing process, Zumbrota Drivetrain performs a comprehensive inspection of all components. This includes a thorough check for straightness, cracks, and surface wear on axle tubes and housings. All internal parts, such as ring and pinions, internal gears, clutches, and carriers, are meticulously inspected and tested. To ensure optimal performance and longevity, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The gears are carefully inspected for proper tooth contact patterns and set to the correct rolling torque using inch-pound measurements, with precise backlash settings for adequate lubrication and quiet operation. Zumbrota utilizes an exclusive cleaning procedure, starting with a hydro-blast rinse and sandblasting of both internal and external parts. This is followed by a proprietary shot-enticed deep cleaning process, which sets a high standard for axle assembly remanufacturing and restores housings to an OEM finish. The axle tubes are inspected to ensure they are straightened to OEM specifications, and housings are tested for surface wear and cracks. Technical specifications for this assembly include a 4.30 ratio, Dana 80 axle type, 11.25-inch ring gear size, and dual rear wheel drivetrain configuration. It is identified by tag numbers 1C34-CB and DB and does not include posi-traction. Please note that this assembly does not include hubs, brakes, backing plates, or axle shafts. Fitment information should be confirmed, as this unit is specifically listed for a 2001 Ford F450 with the 4.30 ratio and requires checking the tag number. It is also listed as compatible with 1989-2002 Dodge vehicles with a 5.9L Cummins Engine.
