8.0 Inch IFS Axle Assembly 3.92 Ratio

The Zumbrota Drivetrain RAA440-1393B is a remanufactured axle assembly engineered for Independent Front Suspension (IFS) systems with an 8.0-inch ring gear. This specific unit is designed with a 3.92 gear ratio and is compatible with 2004-2009 Dodge Durango models. Each Zumbrota Drivetrain axle assembly is rebuilt to rigorous quality standards, ensuring precision and reliability. The remanufacturing process includes a comprehensive 100% inspection of all internal components, such as the ring and pinion gears, internal gears, clutch packs, and carriers. To guarantee optimal performance and longevity, all wearable parts are replaced, including bearings, seals, crush sleeves, pinion nuts, and shims. Furthermore, the housings are meticulously cleaned using a state-of-the-art hydro blasting and rinsing process, restoring them to an OEM finish, and ensuring they are free from surface wear and cracks. Proper setup is critical for the lifespan of the axle. Zumbrota ensures the correct rolling torque is established using precise inch-pound measurements during the assembly process. The units are shipped in high-density plastic totes to protect them from in-transit damage. A refundable core charge of $400 applies to this purchase, which is returned upon receipt of your old, salvageable part.
