Remanufactured Axle Assembly 3.31 Ratio

The Zumbrota Drivetrain RAA440-1350B is a remanufactured axle assembly engineered for specific Ford 8.8 IFS applications, featuring a 3.31 gear ratio. This unit is built to the highest quality standards, focusing on precision and reliability for your vehicle's drivetrain. Each axle assembly is subjected to rigorous inspection for structural integrity, including checks for straightness, cracks, and surface wear. Internally, all components such as ring and pinions, gears, clutches, and carriers are meticulously inspected and tested. As part of the remanufacturing process, all bearings and seals are replaced, and gears are checked for optimal tooth contact patterns and correct rolling torque, measured in inch-pounds for precise setup and longevity. Proper gear backlash is set to ensure quiet operation and effective gear lubrication. 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 meticulous cleaning ensures the housings are returned to an OEM finish, setting a high standard for remanufactured axle assemblies. The units are shipped in high-density plastic totes to minimize damage during transit. This axle assembly is specifically designed for Ford 8.8 IFS applications from 1997-2004, with a 3.31 gear ratio. It requires Non-Synthetic 80w-90 fluid, with a capacity of 2.2 quarts, and does not come pre-filled with oil.
