Remanufactured Complete Axle Assembly 4.11 Ratio 12-Bolt

The Zumbrota Drivetrain RAA435-2234B is a remanufactured complete axle assembly built to the highest quality standards for precision and reliability. This unit is designed for Dana 60 rear axles, featuring a 4.11 gear ratio and a 12-bolt cover. It is specifically designed for 2005-2009 GM Van 3500 models that are equipped without active brakes and have single rear wheels. This complete axle assembly undergoes a rigorous remanufacturing process. All housings are thoroughly inspected for straightness, cracks, and surface wear. Internally, every component, including the ring and pinion, internal gears, clutches, and carriers, is 100% inspected. To ensure longevity and performance, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. Gears are meticulously inspected for optimal tooth contact patterns and correct rolling torque, set using inch-pound measurements for precise setup. Zumbrota utilizes an exclusive hydro-blast rinse and sandblasting procedure on both internal and external parts, followed by a proprietary shot-enticed deep cleaning process. This ensures that all housings are cleaned to OEM finish standards and all tubes are inspected to meet OEM specifications for straightness. The assembly is completed with correct gear backlash set to ensure proper gear lubrication and quiet operation. It is important to note that this is an assembly only and does not include the axles themselves.
