{"product_id":"remanufactured-axle-assembly-3-15-ratio-6-lug","title":"Remanufactured Axle Assembly 3.15 Ratio 6-Lug","description":"The Zumbrota Drivetrain RAA435-212F-P is a meticulously remanufactured axle assembly engineered for 2012-2013 Ford F-150 models equipped with the 9.75-inch ring gear. This unit boasts a 3.15 gear ratio and 6-lug axles, paired with a Posi-traction differential to optimize grip and performance.\n\nDuring the remanufacturing process, Zumbrota Drivetrain adheres to stringent quality standards. Every axle assembly undergoes thorough inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, gears, clutches, and carriers, are inspected and tested. Crucially, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The gears are set for optimal tooth contact patterns and precise rolling torque, ensuring longevity and quiet operation.\n\nZumbrota employs an exclusive hydro-blast rinse and sandblasting procedure for both internal and external parts, followed by a proprietary deep cleaning process. This ensures that housings are restored to OEM finish standards and meet OEM specifications for straightness. The \"Technical Notes\" specify that this assembly does not include hubs, brakes, backing plates, or axle shafts, and it is without an electric locking differential, but includes Posi Traction.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870874104120,"sku":"RAA435-212F-P","price":2792.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/remanufactured-axle-assembly-3-15-ratio-6-lug","provider":"MOTORMIA","version":"1.0","type":"link"}
