3.73 Posi Limited Slip Rear Differential Assembly

The Zumbrota Drivetrain RAA435-2045C-P is a remanufactured rear differential assembly designed for Ford 10.5-inch axles. This assembly features a 3.73 gear ratio and includes a Posi Limited Slip Differential for enhanced traction. Zumbrota Drivetrain Axle Assemblies are rebuilt to high standards of precision and reliability, with each unit thoroughly inspected for straightness, cracks, and surface wear. All internal components, including ring and pinions, gears, clutches, and carriers, are fully inspected and tested. All bearings and seals are replaced, and gears are meticulously inspected for optimal tooth contact patterns and correct rolling torque to ensure precise setup and longevity. Correct gear backlash is set for proper lubrication and quiet operation, and axle tubes are checked to ensure OEM standards of straightness. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure on internal and external parts, followed by a proprietary shot-enticed deep cleaning process. This rigorous remanufacturing process sets the standard for axle assembly quality. This specific assembly is for Single Rear Wheels (SRW) and is compatible with models except for Cab Chassis configurations. It is designed for Ford 10.5-inch ring gear axles with a 3.73 gear ratio and Posi Traction. The assembly includes the cover but does not include fluid.
