Remanufactured Axle Assembly, 3.27 Ratio Posi Traction

The Zumbrota Drivetrain RAA435-1699G-P is a remanufactured complete axle assembly engineered for Ford 8.8" rear differentials. This unit comes equipped with a 3.27 gear ratio, is designed to work with 10" brake systems, and features a Posi Traction limited-slip differential for enhanced traction. Each axle assembly is meticulously rebuilt to stringent quality standards. Zumbrota Drivetrain thoroughly inspects each unit for straightness, cracks, and surface wear. All internal components, including ring and pinions, gears, clutches, and carriers, undergo comprehensive inspection and testing. To ensure reliability and longevity, all bearings and seals are replaced, and gears are meticulously inspected for optimal tooth contact patterns and correct rolling torque. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process for both internal and external parts. This rigorous cleaning and remanufacturing process ensures that the axle housings meet OEM specifications for straightness and are free from defects. The correct gear backlash is precisely set to guarantee proper gear lubrication and quiet operation.
