Chrysler 8.25" 3.21 Ratio Remanufactured Axle Assembly

The Zumbrota Drivetrain RAA435-139C-P is a remanufactured complete axle assembly, meticulously rebuilt to meet high standards of precision and reliability. This unit is designed for Chrysler 8.25 inch axles and features a 3.21 gear ratio, coupled with a Posi Traction limited-slip differential. The assembly includes a 10-bolt round cover and is intended for specific model years and vehicle types. Each Zumbrota axle assembly undergoes a rigorous inspection process. This includes checking for straightness, cracks, and surface wear on housings, as well as a 100% inspection of all internal components such as ring and pinions, internal gears, clutches, and carriers. To ensure longevity and performance, all bearings and seals are replaced, and gears are inspected for optimal tooth contact patterns and correct rolling torque. Backlash is precisely set for proper gear lubrication and quiet operation. Zumbrota employs an exclusive cleaning process, utilizing hydro-blasting and sandblasting, followed by a proprietary shot-enticed deep cleaning procedure. This comprehensive remanufacturing approach sets a high standard for axle assemblies. It's important to note that this assembly does not include hubs, brakes, backing plates, or axle shafts, which must be sourced separately. This remanufactured axle assembly is specifically designed for 2007-2009 Chrysler Aspen and Dodge Durango models equipped with the 8.25 inch axle and a 3.21 ratio Posi limited-slip differential.
