This unit features a 3.90 gear ratio and a 12-bolt hexagon cover, designed to meet the demanding standards of precision and reliability.\n\nEach axle assembly undergoes a rigorous remanufacturing process. Internal components, including ring and pinions, gears, clutches, and carriers, are thoroughly inspected and tested. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The gears are meticulously inspected for optimal tooth contact patterns and set to the correct rolling torque using inch-pound measurements to ensure precise setup and longevity. Proper gear backlash is also set to guarantee adequate gear lubrication and quiet operation.\n\nZumbrota Drivetrain employs an exclusive cleaning procedure that includes hydro-blasting and sandblasting for both internal and external parts, followed by a proprietary shot-peened deep cleaning process. This comprehensive approach ensures that the axle housings meet OEM specifications for straightness and are tested for surface wear and cracks, restoring them to an OEM finish.\n\nThis specific axle assembly has a 3.90 ratio and is designed for Chrysler 9.25\" ring gears. It features a 12-bolt hexagon cover and is configured without Posi Traction. It does not include hubs, brakes, backing plates, or axle shafts.
