Remanufactured Axle Assembly 3.42 Ratio

The Zumbrota Drivetrain RAA435-1404A is a remanufactured axle assembly engineered for precise fit and reliable performance in 1982-1987 GM Camaro and Firebird models. This assembly is specifically designed for vehicles equipped with the GM 7.5-inch (10-bolt) rear axle, featuring a 3.42 gear ratio and disc brakes. Each Zumbrota Complete Axle Assembly is rebuilt to stringent quality standards. The remanufacturing process includes a thorough inspection of all housings for surface wear and cracks. Internally, every component, including ring and pinions, gears, clutches, and carriers, is inspected 100%. Furthermore, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced as part of the remanufacturing process to ensure longevity and optimal performance. Zumbrota employs advanced cleaning techniques, utilizing a state-of-the-art hydro-blasting and rinsing process, along with sandblasting, to restore housings to OEM finish. Axle tubes are meticulously inspected to ensure they meet OEM standards for straightness. The assembly process focuses on precision, with gears inspected for optimal tooth contact patterns and rolling torque established using inch-pound measurements for accurate setup and extended service life. Correct gear backlash is set to ensure proper lubrication and quiet operation. This RAA435-1404A is an assembly only and does not include the axles themselves. Due to variations in vehicle specifications, Zumbrota Drivetrain recommends using their SureFit Order Form to confirm correct application.
