{"product_id":"rear-axle-assembly-4-88-ratio","title":"Rear Axle Assembly 4.88 Ratio","description":"The Zumbrota RAA435-212X2-P is a rear axle assembly featuring a Ford 9.75 differential with a 4.88 gear ratio and a Duragrip limited-slip differential.\n\nZumbrota drivetrain axle assemblies are rebuilt to the highest quality standards. Each unit undergoes rigorous inspection for straightness, cracks, and surface wear. All internal components, including the ring and pinion, gears, clutches, and carrier, are thoroughly inspected and tested. To ensure optimal performance and longevity, all bearings and seals are replaced, and gear setups are meticulously checked for proper tooth contact patterns and rolling torque using precise inch-pound measurements.\n\nThe tubes are inspected and straightened to OEM specifications, and housings are tested for surface wear and cracks. While this assembly is designed for enhanced performance, it is important to note that it does not come with pre-filled oil and requires a 4.88 gear ratio.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870874759480,"sku":"RAA435-212X2-P","price":3359.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/rear-axle-assembly-4-88-ratio","provider":"MOTORMIA","version":"1.0","type":"link"}
