Front Axle Assembly 9.25-Inch Ring Gear 3.42 Ratio

The Zumbrota Drivetrain RAA434-1974A is a remanufactured front axle assembly designed for the 2013 Dodge Ram 3500. This unit features a 9.25-inch ring gear and a 3.42 gear ratio, ensuring proper power transfer for demanding applications. Each axle assembly undergoes a rigorous remanufacturing process. Zumbrota Drivetrain meticulously inspects all components for straightness, cracks, and surface wear. Internal parts, including ring and pinions, internal gears, clutches, and carriers, are thoroughly tested. All bearings and seals are replaced with new ones to guarantee reliability and performance. The gears are precisely set for optimal tooth contact patterns and rolling torque, with correct backlash established for proper lubrication and quiet operation. Axle tubes are also inspected to meet OEM standards for straightness. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peened deep cleaning process. This commitment to cleanliness and precision sets a high standard for axle assembly remanufacturing. This assembly includes the main housing and internals only; it does not include axles, ball joints, spindles, steering components, or brakes.
