{"product_id":"ford-8-8-duragrip-rear-axle-assembly","title":"Ford 8.8 Duragrip Rear Axle Assembly","description":"The Zumbrota RAA435-1962X1-P is a performance rear axle assembly specifically engineered for the Ford 8.8 system, suitable for 1999-2004 Ford Mustang models. This unit features a Duragrip limited-slip differential and a 3.73 gear ratio, designed to enhance traction, support higher speeds, and accommodate heavier towing capabilities beyond standard OE replacement.\n\nEach Zumbrota Performance Axle assembly is meticulously rebuilt to stringent quality standards. The process includes thorough inspection of all components for straightness, cracks, and wear. Internal parts such as ring and pinions, gears, clutches, and carriers are inspected and tested. All bearings and seals are replaced, and gears are checked for optimal tooth contact patterns and correct rolling torque for precise setup and longevity. Zumbrota employs a unique hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peening deep cleaning process, establishing a high standard for axle assembly remanufacturing.\n\nThe tubes are inspected and straightened to OEM specifications, and the housings are tested for surface wear and cracks. While the differential cover is included, the unit does not come pre-filled with oil, requiring the user to add lubricant after installation.\n\nIt's important to note that the Zumbrota Drivetrain® RAA435-1962X1-P is specifically for the '99-'04 Ford Mustang, excluding Cobra models. This item is special ordered and may have cancellation or return restrictions.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870804832568,"sku":"RAA435-1962X1-P","price":1830.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/ford-8-8-duragrip-rear-axle-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
