The Zumbrota Drivetrain RAA435-2118C-P is a remanufactured complete axle assembly, built to high standards of precision and reliability for GM 8.0-inch axles. Each assembly undergoes thorough inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, internal gears, clutches, and carriers, are meticulously inspected and tested. This axle assembly is designed for 2002-2005 GMC Envoy and Chevy Trailblazer models and features a 4.10 gear ratio with G80 Posi Traction. It is built for vehicles with a 113-inch wheelbase and is specifically for the AAM 8-inch ring gear. Note that this assembly does not include hubs, brakes, backing plates, or axle shafts. Zumbrota's remanufacturing process includes replacing all bearings and seals, and gears are inspected for optimal tooth contact patterns and correct rolling torque. They utilize a precise setup with inch-pound measurements for longevity and ensure correct gear backlash for proper lubrication and quiet operation. Axle tubes are inspected and straightened to OEM specifications. Internal and external parts undergo an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peened deep cleaning process, setting a high standard for axle assembly remanufacturing. This attention to detail ensures a quality product ready for installation.
