{"product_id":"11-5-inch-differential-cover-4-10-ratio","title":"11.5 Inch Differential Cover 4.10 Ratio","description":"This unit is specifically built for dual rear wheel applications and features a Posi Traction system for improved grip. It has a 4.10 gear ratio paired with an AAM 11.5 Inch ring gear, ensuring optimal power transfer.\n\nEach axle assembly undergoes a rigorous remanufacturing process to meet the highest quality standards. This includes thorough inspection of housings for straightness, cracks, and surface wear, as well as testing of all internal components such as ring and pinions, internal gears, clutches, and carriers. All bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The gears are meticulously inspected for optimal tooth contact patterns and correct rolling torque, measured in inch-pounds for precise setup and longevity. Correct gear backlash is set to ensure proper lubrication and quiet operation. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peened deep cleaning, setting a benchmark for axle assembly remanufacturing.\n\nHowever, it is important to note that hubs, brakes, backing plates, and axle shafts are not included and must be sourced separately.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870880100664,"sku":"RAA435-2161B-P","price":4060.89,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/11-5-inch-differential-cover-4-10-ratio","provider":"MOTORMIA","version":"1.0","type":"link"}
