8.8-Inch Ring Gear Axle Assembly

The Zumbrota Drivetrain RAA435-2164B is a remanufactured complete axle assembly designed to provide reliable performance. This unit features an 8.8-inch ring gear and a 3.27 gear ratio, incorporating ABS and a Posi Limited Slip Differential (LSD) for enhanced traction and control. Each Zumbrota axle assembly undergoes a rigorous inspection process, including checks for housing straightness, cracks, and surface wear. All internal components, such as the ring and pinion, gears, clutches, and carriers, are meticulously inspected and tested. To ensure optimal performance and longevity, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The assembly also includes a new cover, though fluid is not supplied. The manufacturing process emphasizes precision, with gears inspected for optimal tooth contact patterns and rolling torque set using inch-pound measurements. Axle tubes are verified to meet OEM straightness standards. Zumbrota utilizes a unique hydro-blasting and sandblasting procedure on both internal and external parts, followed by a deep cleaning process to restore housings to their original finish. This axle assembly is compatible with Ford Crown Victoria models from 2003-2011 and Mercury Grand Marquis models from 2003-2011. It is crucial to confirm fitment with your specific vehicle before placing an order to minimize the risk of ordering the wrong product. Fitment issues can lead to returns that may be subject to restocking fees, though exceptions may apply if fitment was confirmed by the sales team and the item does not fit.
