Front Axle Assembly 4.88 Ratio Open Differential

The Zumbrota Drivetrain RAA440-131X2 is a remanufactured front axle assembly built for GM 8.25 IFS vehicles. It comes equipped with a 4.88 ratio and an open differential, featuring a non-posi carrier. Zumbrota emphasizes precision and reliability in their rebuilding process, ensuring that each axle assembly is thoroughly inspected for straightness, cracks, and surface wear. All internal components, including ring and pinions, gears, clutches, and carriers, are meticulously examined and tested. New bearings and seals are installed, and the gears are inspected for optimal tooth contact patterns and correct rolling torque for precise setup and longevity. It serves as an upgrade from OE replacements when larger tires, higher horsepower, or towing demands a stronger drivetrain. Zumbrota Performance Axles are a standard in remanufacturing, offering aftermarket gear upgrades for enhanced performance tailored to the driver's needs. Custom options like Limited Slip Differentials and Lockers can further personalize performance. All tubes are straightened to OEM specifications, and housings are tested for wear and cracks.
