{"product_id":"4-30-posi-limited-slip-differential-assembly","title":"4.30 Posi Limited Slip Differential Assembly","description":"The Zumbrota Drivetrain RAA435-1978C-P is a remanufactured axle assembly built to high standards of precision and reliability. This assembly features a robust 10.5-inch ring gear and a 4.30 gear ratio, paired with a Posi Limited Slip Differential for enhanced traction. Each unit undergoes thorough inspection, including checks for straightness, cracks, and surface wear. All internal components, such as the ring and pinion, internal gears, clutches, and carriers, are fully inspected and tested. To ensure longevity and optimal performance, all bearings and seals are replaced, and gears are meticulously set for proper tooth contact patterns, correct rolling torque, and precise backlash.\n\nZumbrota employs a rigorous cleaning process, including an exclusive hydro-blast rinse and sandblasting, followed by a proprietary shot-peened deep cleaning. This process sets a high standard for remanufactured axle assemblies. The axle tubes are inspected to ensure they meet OEM standards of straightness. This particular assembly is designated as a full-floating axle type and includes the differential cover, though fluid is not provided.\n\nThis axle assembly is specifically designed for 1999-2000 Ford F250 and F350 models with Single Rear Wheels (SRW) and a 10.5-inch ring gear. It is important to note that this assembly is explicitly stated to be an exception for Cab Chassis models, meaning it will not fit those configurations. Buyers are advised to check the tag on their existing differential to ensure compatibility.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870810829112,"sku":"RAA435-1978C","price":2136.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/4-30-posi-limited-slip-differential-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
