4.10 Posi Traction Differential Carrier

The Zumbrota Drivetrain RAA435-112B-P is a remanufactured axle assembly engineered for precise fit and reliable performance in select 2007-2008 Chevrolet Avalanche, Suburban 1500, Tahoe, and GMC Yukon/Yukon XL models. Each Zumbrota axle assembly undergoes a meticulous remanufacturing process. This includes thorough inspections of the housing for straightness, cracks, and surface wear, alongside a complete 100% replacement of all bearings, seals, crush sleeves, pinion nuts, and shims. Internal components such as ring and pinions, gears, clutches, and carriers are also fully inspected and tested. The process ensures correct rolling torque is established using inch-pound measurements for optimal setup and longevity, and axle tubes are straightened to OEM specifications. The housings are cleaned using a state-of-the-art hydro-blasting and rinsing process to restore an OEM finish. This axle assembly has a 4.10 gear ratio and a "posi traction" differential. Technical notes specify that it is for a GM 14 Bolt 9.5 Inch Ring Gear, Ratio Option GT5, and explicitly states it "Does Not Include Hubs, Brakes, Backing Plates, Or Axle Shafts." The product is built to order and includes a $400 refundable core charge. Zumbrota Drivetrain stands behind its products, offering a 2-year limited warranty. The company also emphasizes customer support, encouraging buyers to confirm fitment with their team to avoid ordering errors and ensure a smooth installation process.
