8.8-Inch 3.08 Posi Limited Slip Rear Axle Assembly

The Zumbrota Drivetrain RAA435-1556B-P is a remanufactured rear axle assembly, rebuilt to meet high standards of precision and reliability. This unit is equipped with an 8.8-inch ring gear, a 3.08 gear ratio, and a Posi Limited Slip Differential for enhanced traction. Each Zumbrota axle assembly undergoes thorough inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, gears, clutches, and carriers, are fully inspected and tested. To ensure longevity and optimal performance, all bearings and seals are replaced, and gears are inspected for correct tooth contact patterns and rolling torque. Correct gear backlash is set for proper lubrication and quiet operation, and axle tubes are checked for OEM straightness. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process for its internal and external parts, setting a high standard for axle assembly remanufacturing. This specific assembly is designed for 1991-1994 Ford Explorer and Navajo models and includes provisions for ABS. Key specifications include an 8.8-inch Ford-built ring gear, a 3.08 gear ratio, Posi Traction capability, and a semi-floating axle type. The assembly comes with a cover, but does not include fluid.
