{"product_id":"rear-axle-assembly-4-88-open-differential","title":"Rear Axle Assembly 4.88 Open Differential","description":"The Zumbrota Performance Axle is a remanufactured rear axle assembly built to high standards of precision and reliability, intended for GM 8.6 inch axles. This assembly comes with an aftermarket 4.88 gear ratio and an open differential, suitable for applications requiring stronger traction, higher speeds, or heavier towing capabilities beyond stock. Each axle assembly undergoes thorough inspection for straightness, cracks, and surface wear, ensuring the integrity of all tubes and housings. All internal components, including ring and pinions, gears, clutches, and carriers, are inspected and tested. New bearings and seals are installed, and the gears are checked for optimal tooth contact patterns and correct rolling torque for precise setup and longevity. Zumbrota utilizes an exclusive hydro-blast rinse, sandblasting, and proprietary shot-enticed deep cleaning procedure in their remanufacturing process.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870770590008,"sku":"RAA435-172X3","price":3276.78,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/rear-axle-assembly-4-88-open-differential","provider":"MOTORMIA","version":"1.0","type":"link"}
