Remanufactured Axle Assembly 4.10 Posi Traction Dual Rear Wheel

The Zumbrota Drivetrain RAA435-2161D-P is a remanufactured axle assembly designed for AAM 11.5-inch differentials. This unit features a 4.10 gear ratio, Posi Traction, and is specifically intended for Dual Rear Wheel (DRW) configurations. This axle assembly undergoes a comprehensive remanufacturing process. All housing tubes are inspected and straightened to OEM specifications, while the housings themselves are rigorously tested for surface wear and cracks. Internally, all components, including ring and pinion gears, internal gears, clutches, and carriers, are subjected to a 100% inspection. Zumbrota Drivetrain ensures longevity and precision by replacing 100% of bearings, seals, crush sleeves, pinion nuts, and shims. The housings are then cleaned using an advanced hydro blasting and rinsing process to achieve an OEM finish. Key specifications include an 11.5-inch ring gear size and Posi Traction for enhanced performance. This assembly does not include hubs, brakes, backing plates, or axle shafts, meaning these components may need to be transferred from the original unit or purchased separately. This axle assembly is designed for 2004-2005 Chevrolet/Dodge Ram 3500 2WD models with Dual Rear Wheels and the 4.10 Posi Traction differential.
