8.25" Differential Axle Assembly 3.73 Posi

The Zumbrota Drivetrain RAA435-2242B-P is a remanufactured axle assembly designed for the Chrysler 8.25-inch differential. This unit comes equipped with a 3.73 gear ratio and a Posi Limited Slip Differential, ensuring enhanced traction and performance. Each axle assembly undergoes a rigorous remanufacturing process by Zumbrota Drivetrain. This includes a comprehensive inspection of all components for straightness, cracks, and surface wear. Internal parts, such as ring and pinions, gears, and clutches, are thoroughly inspected and tested. All bearings and seals are replaced to ensure reliability. The gears are meticulously examined for optimal tooth contact patterns and set to precise rolling torque using inch-pound measurements for maximum setup accuracy and longevity. Furthermore, correct gear backlash is established to guarantee proper gear lubrication and quiet operation. The axle tubes are also inspected to meet OEM standards for straightness. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure for both internal and external parts. This is followed by a proprietary shot-enticed deep cleaning process, which establishes a benchmark for axle assembly remanufacturing quality. Key specifications include an 8.25-inch ring gear diameter, Chrysler fitment, a 3.73 gear ratio, and compatibility with models without ABS but with Posi Traction. The axle type is semi-floating, and a cover is included, though fluid is not provided.
