{"product_id":"9-25-inch-ring-gear-4-10-1-ratio-axle-assembly","title":"9.25-Inch Ring Gear 4.10:1 Ratio Axle Assembly","description":"The Zumbrota Drivetrain RAA434-121C is a remanufactured axle assembly designed for precision and reliability. It features a 9.25-inch AAM ring gear and a 4.10:1 gear ratio, suitable for open differential applications. This assembly includes the main housing and all internal differential components, but excludes axles, ball joints, spindles, steering components, and brakes.\n\nEach axle assembly undergoes rigorous inspection for straightness, cracks, and surface wear. Zumbrota Drivetrain meticulously inspects and tests all internal components, including ring and pinions, internal gears, and clutches. To ensure optimal performance and longevity, all bearings and seals are replaced, gears are inspected for proper tooth contact patterns, and rolling torque is set using precise inch-pound measurements. Proper gear backlash is established for correct lubrication and quiet operation, while axle tubes are verified against OEM standards for straightness.\n\nZumbrota utilizes an exclusive cleaning process that involves hydro-blasting and sandblasting of internal and external parts, followed by a proprietary shot-enticed deep cleaning procedure. This method sets a high standard for the remanufacturing of axle assemblies.\n\nThis specific RAA434-121C axle assembly is designed to fit the 2009 Dodge Ram 1500. It is important to verify fitment before purchase, as indicated by the product page stating \"Your Selected Vehicle Does Not Fit, Please Select a Vehicle\" if the wrong vehicle is chosen.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870718685496,"sku":"RAA434-121C","price":3299.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/9-25-inch-ring-gear-4-10-1-ratio-axle-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
