Each unit undergoes a thorough inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, gears, clutches, and carriers, are fully inspected and tested. To guarantee longevity and optimal performance, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The gear backlash is precisely set to ensure proper lubrication and quiet operation, with ring and pinion gears inspected for ideal tooth contact patterns and correct rolling torque measured in inch-pounds.\n\nZumbrota employs an exclusive hydro-blast rinse and sandblasting procedure on both internal and external parts, followed by a proprietary shot-peening deep cleaning process. This comprehensive cleaning method sets a high standard for axle assembly remanufacturing, ensuring the housings are returned to an OEM finish and meet OEM specifications for straightness.\n\nThis specific assembly is configured with a 4.11 gear ratio and is designed for 2WD, Single Rear Wheel (SRW) applications, featuring a Posi Limited Slip Differential (LSD).","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870764003640,"sku":"RAA435-1661C-P","price":4426.39,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/4-11-ratio-posi-lsd","provider":"MOTORMIA","version":"1.0","type":"link"}
