Remanufactured Front Differential Assembly 3.42 Ratio

The Zumbrota Drivetrain RAA440-1353A is a remanufactured axle assembly designed to provide precision and reliability for GM 7.2 IFS front differentials. This unit features a 3.42 gear ratio and is specifically engineered for the 1999-2005 GMC Astro and Safari models. Zumbrota Drivetrain adheres to rigorous quality standards in their remanufacturing process. Each axle assembly is subjected to a comprehensive inspection, checking for housing straightness, cracks, and surface wear. Internally, all components such as ring and pinions, gears, clutches, and carriers are fully inspected and tested to ensure they meet OEM specifications. To guarantee longevity and optimal performance, Zumbrota replaces all bearings, seals, crush sleeves, pinion nuts, and shims. The gears are inspected for precise tooth contact patterns and correct rolling torque, established using inch-pound measurements. Proper gear backlash is set to ensure adequate gear lubrication and quiet operation. The housings undergo a state-of-the-art hydro-blasting and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process, restoring them to OEM finish. Units are shipped in high-density plastic totes to minimize the risk of in-transit damage. This remanufactured axle assembly is built to meet the highest quality standards, providing a reliable and durable replacement for your vehicle's drivetrain.
