This unit features a 3.21 gear ratio, a 10-bolt round cover, and 29-spline axles, specifically configured without Posi Traction.\n\nEach Zumbrota axle assembly is rebuilt with a focus on precision and reliability. The remanufacturing process includes a comprehensive inspection of the housing for straightness, cracks, and surface wear, ensuring it meets OEM standards. Internally, all components—including the ring and pinion, gears, clutches, and carriers—are meticulously inspected and tested. To guarantee longevity and optimal performance, Zumbrota replaces all bearings and seals, and sets the correct gear backlash and rolling torque using inch-pound measurements.\n\nThe cleaning process is also a critical step in Zumbrota's remanufacturing. Housings are cleaned using a state-of-the-art hydro-blasting and rinsing procedure, restoring them to an OEM finish. This rigorous approach ensures that each axle assembly performs reliably and quietly.\n\nKey specifications include an 8.25-inch ring gear diameter, a 3.21 gear ratio, a 10-bolt round cover type, 29 spline count, and a semi-floating axle type. This assembly does not include differential fluid. It is a remanufactured part, rebuilt to exacting standards for durability and precision. Fitment information indicates it is for 1997 Dodge B1500 and B2500 models with a 3.9L engine.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870751912248,"sku":"RAA435-1577AL","price":1602.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/remanufactured-axle-assembly-chrysler-8-25-inch-3-21-ratio","provider":"MOTORMIA","version":"1.0","type":"link"}
