Dana 80 4.10 Posi Traction Axle Assembly

The Zumbrota Drivetrain RAA435-2125B-P is a remanufactured axle assembly designed for the Dana 80 rear differential. This assembly is rebuilt to stringent quality standards, ensuring precision and reliability. Each unit undergoes thorough inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, internal gears, clutches, and carriers, are meticulously inspected and tested. Key features of this axle assembly include a 4.10 gear ratio and a Posi Traction limited-slip differential, making it suitable for applications requiring enhanced traction. The Dana 80 housing has an 11.25-inch ring gear diameter, and the assembly is compatible with tag numbers 1C34-LA, 2C34-AAA, and 2C34-AAB. Zumbrota Drivetrain emphasizes the quality of their remanufacturing process. All bearings and seals are replaced, and gears are inspected for optimal tooth contact patterns and correct rolling torque, measured in inch-pounds for precise setup and longevity. Gear backlash is set to ensure proper lubrication and quiet operation. The axle tubes are inspected to meet OEM standards for straightness. Zumbrota utilizes an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process to set a high standard for axle assembly remanufacturing. This specific assembly includes the differential cover but does not include hubs, brakes, backing plates, or axle shafts. It is designed for use with 2001-2004 Ford F-350 Super Duty models that are equipped with dual rear wheels and are cab chassis variants.
