Description

The Zumbrota Drivetrain RAA435-1858A-P is a remanufactured complete axle assembly for the Dana 80 rear end, specifically engineered for 1996-1999 Dodge Ram 3500 Cab Chassis models. This assembly comes with a 3.54 gear ratio and features Posi Traction for enhanced performance. It is built with rigorous quality control measures, including 100% inspection of all internal parts such as the ring and pinion, gears, clutches, and carriers. Housings are tested for cracks and straightened to OEM specifications, while all bearings, seals, and critical setup components like crush sleeves and pinion nuts are replaced to ensure longevity and precise operation. The remanufacturing process includes a thorough cleaning via hydro blasting to achieve an OEM finish. Key specifications include an 11.25-inch ring gear size and a 10-bolt cover count. However, it is important to note that this axle assembly does not include hubs, brakes, backing plates, or axle shafts, which must be sourced separately.
