P 3.73 Gear Ratio Rear Axle Assembly

The Zumbrota Drivetrain RAA435-158A-P is a remanufactured axle assembly built to exacting standards for precision and reliability. This assembly is designed for the Dana 80 differential, featuring an 11.25-inch ring gear and a 3.73 gear ratio. Each axle assembly undergoes rigorous inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, gears, clutches, and carriers, are thoroughly inspected and tested. Zumbrota replaces all bearings and seals, ensuring optimal performance. The gears are meticulously inspected for proper tooth contact patterns and set to precise rolling torque specifications using inch-pound measurements for longevity and quiet operation. The axle tubes are also inspected to ensure they meet OEM standards for straightness. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peened deep cleaning process on both internal and external parts. This comprehensive remanufacturing process sets a high standard for axle assembly quality. This specific axle assembly is compatible with 2005-2007 Ford F350 Dual Rear Wheel (DRW) models. It is important to note that this assembly is **except cab chassis** models.
