Complete Axle Assembly 4.10 Ratio 10.5-Inch Ring Gear

The Zumbrota Drivetrain RAA435-2045B is a remanufactured complete axle assembly, meticulously rebuilt to the highest standards of precision and reliability. This assembly is engineered for 2000-2001 Ford F350 Single Rear Wheel (SRW) models with a 4.10 gear ratio and a 10.5-inch ring gear. Each unit undergoes thorough inspection for straightness, cracks, and surface wear, ensuring the housing meets OEM specifications. All internal components, including ring and pinions, gears, and carriers, are fully inspected and tested. Zumbrota replaces all bearings and seals, and meticulously sets up gears for optimal tooth contact, correct rolling torque, and proper backlash to ensure longevity and quiet operation. The remanufacturing process employed by Zumbrota Drivetrain sets a high standard. They utilize an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peened deep cleaning process. This rigorous cleaning ensures internal and external parts are returned to an OEM-like finish. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced as part of the rebuild. This axle assembly is specifically for models without Posi Traction and has a tag number of S161H. Please note that this assembly does not include hubs, brakes, backing plates, or axle shafts, and requires checking the tag for exact fitment. The product comes with a 1-year limited warranty.
