{"product_id":"8-6-rear-axle-assembly-3-42-posi-lsd","title":"8.6\" Rear Axle Assembly 3.42 Posi LSD","description":"The Zumbrota Drivetrain RAA435-172C-P is a remanufactured rear axle assembly designed for 2009-2011 GMC Yukon and Chevrolet Tahoe vehicles. This unit features an 8.6-inch ring gear, a 3.42 axle ratio (GU6 option), and a Posi Limited Slip Differential (LSD), also known as G80 Posi Traction.\n\nZumbrota Drivetrain Axle Assemblies are rebuilt to high standards of precision and reliability. The remanufacturing process includes thorough inspection of all components for straightness, cracks, and surface wear. Internal parts such as ring and pinions, gears, clutches, and carriers are fully inspected and tested. All bearings and seals are replaced, and gears are examined for optimal tooth contact patterns and correct rolling torque, ensuring precise setup and longevity. The differential backlash is set correctly for proper gear lubrication and quiet operation. Axle tubes are inspected to meet OEM standards for straightness. Zumbrota employs a unique hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peened deep cleaning process for its internal and external parts.\n\nThis axle assembly has a 10-bolt cover and is a semi-floating type. While the cover is included, differential fluid is not. It's important to note that this assembly does not include hubs, brakes, backing plates, or axle shafts.","brand":"Zumbrota Drivetrain","offers":[{"title":"Default Title","offer_id":52870770229560,"sku":"RAA435-172C-P","price":2420.6,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/8-6-rear-axle-assembly-3-42-posi-lsd","provider":"MOTORMIA","version":"1.0","type":"link"}
