Front Axle Assembly, 3.92 Ratio

The Zumbrota Drivetrain RAA440-147B is a remanufactured front axle assembly specifically engineered for the 8.0-inch IFS system found in 2006-2011 Dodge Ram 1500 models with a 3.92 gear ratio. This assembly undergoes a rigorous remanufacturing process to meet high standards of precision and reliability. Each unit is meticulously inspected for straightness, surface wear, and cracks. All internal components, including ring and pinions, internal gears, clutches, and carriers, are fully inspected and tested. Zumbrota Drivetrain ensures longevity and quiet operation by replacing 100% of bearings, seals, crush sleeves, pinion nuts, and shims. The gears are set for optimal tooth contact patterns and correct rolling torque, with backlash precisely adjusted for proper gear lubrication. Axle tubes are inspected to ensure they meet OEM standards for straightness. Zumbrota employs an exclusive hydro-blast and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process on all internal and external parts, restoring housings to an OEM finish. Key specifications include a 1.7-quart fluid capacity, requiring non-synthetic 75w-90 fluid. The ring gear diameter is 205. The units are shipped in high-density plastic totes to prevent in-transit damage.
