Description

It features a 7.25-inch Chrysler ring gear, a 3.21 gear ratio, and a Posi Traction differential for enhanced performance. This assembly undergoes a comprehensive remanufacturing process. All tubes are straightened to meet OEM specifications, and housings are meticulously tested for surface wear and cracks. Internal components, including the ring and pinion gears, clutch pack, and carrier, are subjected to a 100% inspection. To ensure reliability and longevity, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The housing is also hydro-blasted and rinsed to restore its original OEM finish, and precise rolling torque is established for optimal setup. Key specifications include a 7.25-inch ring gear diameter, a 3.21 gear ratio, and a 10-bolt hexagon cover. This assembly is equipped with Posi Traction but specifically does not include hubs, brakes, backing plates, or axle shafts. Ensure compatibility with your specific vehicle configuration. Zumbrota Drivetrain stands behind its products with a commitment to quality. This remanufactured axle assembly is built to order and ships when ready, with options for expedited shipping available at checkout. Free shipping is offered on orders over $199, and all reman parts ship for a flat rate of $299.
