10.5-Inch 3.73 Posi Limited Slip Rear Differential Assembly

The Zumbrota Drivetrain RAA435-1976A-P is a remanufactured axle assembly designed for 1999 Ford F-250 and F-350 trucks equipped with the 10.5-inch rear axle. This unit features a 3.73 gear ratio and a Posi Limited Slip Differential, specifically for Single Rear Wheel (SRW) configurations. Zumbrota Drivetrain emphasizes the quality and reliability of their rebuilt axle assemblies. Each unit undergoes thorough inspection for straightness, cracks, and surface wear. Internal components, including ring and pinions, clutches, and carriers, are fully inspected and tested. To ensure longevity and performance, all bearings and seals are replaced, and gears are meticulously checked for optimal tooth contact patterns, correct rolling torque, and precise backlash settings for proper lubrication and quiet operation. Axle tubes are also inspected to meet OEM standards. The remanufacturing process includes an exclusive hydro-blast rinse and sandblasting procedure for internal and external parts, followed by a proprietary shot-enticed deep cleaning, establishing a high standard for axle assembly remanufacturing. This specific assembly is for 10.5 Inch Ring Gear Ford applications with a 3.73 ratio and Posi Traction. Please note that a 'Check Tag' is recommended for verification.
