11.5-Inch 3.73 Posi Traction Differential Assembly

The Zumbrota Drivetrain RAA435-2290B-P is a remanufactured axle assembly designed for the 2012 Chrysler RAM 3500. This assembly is built to stringent quality standards, ensuring precision and reliability for your vehicle's drivetrain. Key specifications include an AAM 11.5-inch ring gear, a 3.73 gear ratio, and a Posi Traction differential, making it suitable for 4x4 and Dual Rear Wheel (DRW) applications. Zumbrota Drivetrain meticulously inspects all internal components, including the ring and pinion gears, internal gears, clutches, and carriers. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts during the remanufacturing process. The housing undergoes a thorough inspection for straightness, cracks, and surface wear, and is cleaned using a state-of-the-art hydro-blasting and rinsing process to restore it to OEM finish standards. Gears are inspected for optimal tooth contact patterns and set to correct backlash for proper lubrication and quiet operation. This axle assembly does not include hubs, brakes, backing plates, or axle shafts.
