Chrysler 8.25-inch 3.90 Posi-Traction Axle Assembly

The Zumbrota Drivetrain RAA435-1577CE-P is a remanufactured axle assembly designed for Chrysler 8.25-inch differentials, featuring a 3.90 gear ratio and Posi-Traction capabilities. Each unit undergoes a rigorous remanufacturing process, including state-of-the-art hydro blasting and rinsing of housings to restore them to an OEM finish. All internal components are meticulously inspected, including ring and pinion gears, clutches, and carriers, with 100% replacement of critical wear items such as bearings, seals, crush sleeves, pinion nuts, and shims. The assembly ensures longevity and precision through the establishment of correct rolling torque using inch-pound measurements. Housings are tested for surface wear and cracks, and tubes are straightened to OEM specifications. The technical notes specify a 3.90 ratio, Chrysler 8.25-inch ring gear, a 10-bolt round cover, and 27 spline axles. This assembly is sold as the axle assembly only and does not include hubs, brakes, backing plates, or axle shafts. Zumbrota Drivetrain builds these units to order, with shipping times typically 1-2 days for most locations, and expedited shipping options available at checkout. A refundable core charge of $400 applies, which is returned upon receipt of the old, salvageable part for recycling or rebuilding.
