Ford 8.8" 3.31 Posi Limited Slip Rear Axle Assembly

The Zumbrota Drivetrain RAA435-2037C-P is a remanufactured axle assembly meticulously rebuilt to exacting standards for precision and reliability. This unit is engineered for the Ford 8.8-inch differential, featuring a 3.31 gear ratio and a Posi Limited Slip Differential, designed to restore optimal performance. Zumbrota Drivetrain ensures the highest quality by thoroughly inspecting each axle assembly for straightness, cracks, and surface wear. All internal components, including ring and pinions, clutches, and carriers, undergo a comprehensive inspection and testing process. To guarantee longevity and precise setup, all bearings and seals are replaced, gears are inspected for optimal tooth contact patterns, and correct rolling torque is set using inch-pound measurements. Proper gear backlash is also established for adequate lubrication and quiet operation. The remanufacturing process includes an exclusive hydro-blast rinse and sandblasting procedure on both internal and external parts, followed by a proprietary shot-enticed deep cleaning, setting a high standard in axle assembly remanufacturing. The axle tubes are inspected to meet OEM standards for straightness. This axle assembly is specifically designed for 1999-2000 Ford F-150 models equipped with rear drum brakes. The assembly includes the differential cover, but fluid is not included. A "Check Tag" is recommended to confirm compatibility with your specific vehicle configuration.
