This unit comes equipped with a Posi Limited Slip Differential, a 3.55 gear ratio, and is configured for drum brake systems. The assembly includes the differential cover, and features 31-spline semi-floating axles.\n\nZumbrota Drivetrain rebuilds these axle assemblies to stringent quality standards, emphasizing precision and reliability. Each unit undergoes thorough inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, gears, clutches, and carriers, are meticulously inspected and tested. Crucially, all bearings and seals are replaced, and gears are inspected for optimal tooth contact patterns and correct rolling torque. Gear backlash is precisely set to ensure proper lubrication and quiet operation, with axle tubes also inspected to meet OEM standards of straightness. Zumbrota employs a proprietary cleaning process involving hydro-blast rinsing, sandblasting, and shot-enticed deep cleaning to prepare the components for remanufacturing.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870883148088,"sku":"RAA435-2181A-P","price":2769.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/8-8-posi-limited-slip-differential-3-55-ratio-31-spline","provider":"MOTORMIA","version":"1.0","type":"link"}
