Remanufactured Axle Assembly, 4.10 Ratio, 10.25-Inch Ring Gear

The Zumbrota Drivetrain RAA435-1496D is a remanufactured axle assembly specifically designed for 1987-1993 Ford F250 models equipped with a 10.25-inch ring gear. This unit features a 4.10 gear ratio and Posi Traction for enhanced grip. It is built for semi-float axles and is sold without hubs, brakes, backing plates, or axle shafts, allowing for customization or integration with existing components. Zumbrota Drivetrain's remanufacturing process involves thorough inspection of all axle components, including ring and pinions, internal gears, clutches, and carriers. All bearings and seals are replaced with new parts. The gears are meticulously inspected for optimal tooth contact patterns and set to precise rolling torque specifications using inch-pound measurements to ensure longevity and quiet operation. Gear backlash is also precisely set for proper lubrication and performance. Axle tubes are inspected and straightened to meet OEM specifications, and all housings undergo rigorous testing for surface wear and cracks. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary deep cleaning process, to prepare the components to OEM finish standards. This comprehensive approach aims to set the benchmark for remanufactured axle assemblies.
