Complete Axle Assembly 3.73 Ratio

The Zumbrota Drivetrain RAA435-267C is a remanufactured complete axle assembly designed for specific Ford trucks. This unit features a 10.5-inch ring gear and a 3.73 gear ratio, specifically intended for 2011-2012 Ford F-250 and F-350 models equipped with single rear wheels (SRW) and gas engines. Zumbrota Drivetrain prioritizes precision and reliability in their remanufacturing process. Each axle assembly undergoes a thorough inspection of its tubes for straightness, cracks, and surface wear. Internally, all components such as ring and pinions, gears, clutches, and carriers are meticulously inspected and tested. To ensure optimal performance and longevity, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The gears are set to achieve correct tooth contact patterns and rolling torque, measured precisely in inch-pounds, with proper backlash set for lubrication and quiet operation. The remanufacturing process at Zumbrota Drivetrain includes an exclusive hydro-blast rinse and sandblasting procedure for both internal and external parts. This is followed by a proprietary shot-enticed deep cleaning, which sets a high standard for axle assembly remanufacturing and restores housings to an OEM finish. This comprehensive approach ensures that the RAA435-267C assembly meets stringent quality controls.
