Rear Axle Assembly 3.08 Ratio

The Zumbrota Drivetrain RAA435-2037B is a remanufactured axle assembly specifically designed for the Ford 8.8-inch rear differential. This unit features a 3.08 gear ratio and is compatible with models equipped with rear disc brakes. It is intended for use on 1999 and 2000 Ford F-150 trucks. Zumbrota Drivetrain prides itself on rebuilding axle assemblies to the highest quality standards, ensuring precision and reliability. Each assembly undergoes a thorough inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, internal gears, clutches, and carriers, are fully inspected and tested. Crucially, all bearings and seals are replaced with new ones. The gears are meticulously inspected for optimal tooth contact patterns and correct rolling torque, with precise setup and longevity in mind. Gear backlash is set to factory specifications to ensure proper lubrication and quiet operation, while axle tubes are checked to meet OEM straightness standards. Zumbrota utilizes an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peened deep cleaning process, setting a high standard in axle assembly remanufacturing. Key specifications include an 8.8-inch ring gear, Ford construction, Hollander No. 435-237B, a 3.08 gear ratio, rear disc brakes, and it is without Posi Traction. The axle type is semi-floating, and a cover is included, but fluid is not. Buyers should note that this is a special-order item and may have return restrictions. It is also currently out of stock.
