Dana 35IFS Axle Assembly 3.27 Ratio

The Zumbrota Drivetrain RAA440-1288A is a remanufactured Dana 35IFS axle assembly engineered for 1991-1994 Ford Explorers, featuring a 3.27 gear ratio and a 7.5-inch ring gear diameter. This assembly is designed as a standard replacement unit, ensuring compatibility and performance for your vehicle's drivetrain. Zumbrota Drivetrain prioritizes quality and reliability in their remanufacturing process. Each axle assembly undergoes a comprehensive inspection of its housing for straightness, cracks, and surface wear. Internally, all components, including the ring and pinion gears, internal 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 with new parts. The gears are inspected for precise tooth contact patterns and set to the correct rolling torque using inch-pound measurements, with backlash adjusted for proper lubrication and quiet operation. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure on both internal and external parts, followed by a proprietary shot-peening deep cleaning process. This advanced cleaning method restores housings to OEM finish standards. The assembly has a fluid capacity of 1.75 quarts and requires 80W-90 non-synthetic fluid, which is not included. Units are shipped in high-density plastic totes to minimize the risk of in-transit damage, ensuring the product arrives in optimal condition.
