Remanufactured Rear Axle Assembly 3.55 Ratio 9.75 Inch

The Zumbrota Drivetrain RAA435-2021G is a meticulously remanufactured rear axle assembly. This unit features a 3.55 gear ratio, a 9.75-inch ring gear, and is designed for vehicles with rear drum brakes. It includes 14mm wheel studs and 2.533-inch O.D. wheel bearings. Zumbrota Drivetrain has over 30 years of experience providing quality remanufactured transmissions, transfer cases, and differentials. They offer a complete line of parts for a variety of foreign and domestic vehicles. Their remanufacturing process involves a 100 percent inspection of all internal parts, including ring and pinions, gears, clutches, and carriers. Bearings, seals, crush sleeves, pinion nuts, and shims are all replaced with new components. The housings are hydro-blasted to an OEM finish, and gear patterns are checked to ensure optimal tooth contact for increased longevity. Correct rolling torque and backlash clearance are established for precision setup and noise reduction. This specific axle assembly is designed for the 2000 Ford F-150 2WD/4WD Gas model. It features a stepped housing and is an open differential model, meaning it does not have Posi-Traction. The product listing may also refer to specific ID tags like S916C for guaranteed fitment.
