Chrysler 8.25" 3.92 Ratio Axle Assembly

The Zumbrota Drivetrain RAA435-1890C is a remanufactured axle assembly, specifically a complete rear differential, built to rigorous standards for precision and reliability. This unit features a Chrysler 8.25-inch ring gear with a 3.92 gear ratio and is designed for 1997-1999 Dodge Dakota 2WD applications. Each axle assembly is subjected to a comprehensive inspection, verifying straightness, checking for cracks, and assessing surface wear. Internally, all components, including ring and pinions, gears, clutches, and carriers, are meticulously inspected and tested. To ensure longevity and optimal performance, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The gears are evaluated for proper tooth contact patterns, and correct rolling torque is established using precise inch-pound measurements for optimal setup and quiet operation. Zumbrota employs an advanced cleaning process, utilizing hydro-blasting and sandblasting for both internal and external parts, followed by a proprietary shot-enticed deep cleaning. This ensures the housing is restored to OEM finish standards. The assembly includes a cover, but fluid is not provided. Key specifications include a Semi Floating axle type, an 8.25-inch ring gear, a 3.92 gear ratio, and a 10-bolt round cover pattern.
