Dana 50 Remanufactured Axle Assembly 3.73 Ratio

The Zumbrota Drivetrain RAA434-1958A is a remanufactured axle assembly featuring a Dana 50 differential with a 3.73 gear ratio. This includes the ring and pinion gears, internal gears, clutches, and carriers. All bearings and seals are replaced during the remanufacturing process. Zumbrota ensures optimal performance by inspecting gears for correct tooth contact patterns and setting precise rolling torque using inch-pound measurements for longevity. Proper gear backlash is also set to guarantee adequate gear 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, setting a high standard for axle assembly remanufacturing. This specific axle assembly is designed for the 2001-2004 Ford Excursion models equipped with 4-wheel ABS. It includes the main housing and internal components only; it does not include axles, ball joints, spindles, steering components, or brakes. Ensure compatibility with your specific vehicle before purchase, as fitment can vary.
