{"product_id":"3-27-posi-limited-slip-rear-axle-assembly","title":"3.27 Posi Limited Slip Rear Axle Assembly","description":"The Zumbrota Drivetrain RAA435-1466A-P is a remanufactured rear axle assembly designed to replace the original unit on 1986-1993 Ford Mustang models equipped with the Ford 8.8-inch differential and drum brakes. This assembly features a 3.27 gear ratio and a Posi Limited Slip Differential for enhanced traction and performance.\n\nEach Zumbrota axle assembly is rebuilt to stringent quality standards. The process includes a thorough inspection of all internal components such as ring and pinions, gears, clutches, and carriers for wear and proper function. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The gear backlash is meticulously set to ensure proper lubrication and quiet operation, with gears inspected for optimal tooth contact patterns and rolling torque measured with inch-pound gauges for precise setup and longevity. The axle housing and tubes are inspected for straightness and cracks, with any necessary straightening performed to meet OEM specifications.\n\nZumbrota employs an exclusive hydro-blast rinse and sandblasting procedure on internal and external parts, followed by a proprietary shot-peening deep cleaning process. This comprehensive remanufacturing process aims to restore the axle assembly to a high level of reliability and performance. The unit includes the differential cover but does not include hubs, brake components, backing plates, or axle shafts.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870742802744,"sku":"RAA435-1466A","price":1676.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/3-27-posi-limited-slip-rear-axle-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
