Chrysler 8.25" 3.21 Posi Traction Rear Axle Assembly

The Zumbrota Drivetrain RAA435-1437C-P is a remanufactured axle assembly engineered for Chrysler 8.25-inch ring gears, featuring a 3.21 gear ratio and Posi Traction. This assembly is built to rigorous standards, with all tubes inspected and straightened to OEM specifications, and housings tested for surface wear and cracks. Every internal component, including the ring and pinion, gears, clutch, and carrier, receives a thorough 100% inspection. To ensure precision setup and longevity, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced, and correct rolling torque is established using inch-pound measurements. Specifically designed for 1985-1989 Dodge D100, D150, and Ramcharger 2WD models, this unit utilizes a 10-bolt round cover. It's important to note that this axle assembly does not include hubs, brakes, backing plates, or axle shafts, which may need to be sourced separately. The remanufacturing process includes a state-of-the-art hydro blasting and rinsing process for the housings, restoring them to their OEM finish. Zumbrota Drivetrain stands behind their products with a commitment to precision and reliability.
