This unit features a 3.73 gear ratio and a \"Posi\" limited-slip differential, designed to enhance traction and performance.\n\nZumbrota Drivetrain prioritizes precision and reliability in their remanufacturing process. Each axle assembly undergoes rigorous inspection for straightness, cracks, and surface wear. Internal components, including ring and pinions, internal gears, clutches, and carriers, are fully 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 meticulously inspected for proper tooth contact patterns and correct rolling torque, measured precisely using inch-pound specifications. Backlash is set to ensure quiet operation and adequate gear lubrication.\n\nThe assembly process includes a state-of-the-art hydro-blast rinse and sandblasting procedure on all internal and external parts, followed by a proprietary shot-peened deep cleaning process. This cleaning method restores housings to OEM finish standards. Axle tubes are also inspected and straightened to meet OEM specifications, ensuring a straight and true assembly.\n\nKey specifications include an axle type of Semi Floating, a 10-bolt housing cover, a 2.4-quart fluid capacity (fluid not included), a regular grade type, and an 8.8-inch ring gear diameter. The cover is included with the assembly. This axle assembly is specifically noted for the 5.0L engine variant, though a reference to the 3.7L with a 3.31 ratio also appears, indicating potential variations or specific fitments to verify.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870904906040,"sku":"RAA435-276A","price":2792.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/8-8-rear-axle-assembly-3-73-posi-limited-slip","provider":"MOTORMIA","version":"1.0","type":"link"}
