Remanufactured Rear Axle Assembly, GM 7.5-Inch 3.73 Ratio

The Zumbrota Drivetrain RTC594 is a professional-grade remanufactured axle assembly, meticulously rebuilt for select Chevrolet Camaro and Pontiac Firebird models from the 1990-1992 model years. This semi-floating axle is built to exacting standards, featuring a GM 7.5-inch ring gear and a 3.73 ratio, specifically designed without posi-traction. Every Zumbrota axle assembly undergoes a comprehensive inspection process, evaluating housings for straightness, cracks, and surface wear. Critical internal components, including ring and pinions, gears, and clutches, are thoroughly inspected and tested. To ensure optimal performance and durability, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. Precision is paramount, with careful measurement of rolling torque and setting of gear backlash to OEM specifications. Zumbrota employs a state-of-the-art hydro-blasting and rinsing process to restore housings to an OEM-like finish, enhancing both appearance and performance. The proprietary shot-enticed deep cleaning ensures all parts are spotless, setting a high standard for remanufactured axle assemblies. This axle assembly is specifically designed to fit the following vehicles: Chevrolet Camaro RS (1990-1992), Chevrolet Camaro Iroc-Z (1990), Chevrolet Camaro Z28 (1991-1992), Chevrolet Camaro RS Heritage Edition (1992), Chevrolet Camaro Z28 Heritage Edition (1992), Pontiac Firebird Base (1990-1992), Pontiac Firebird Formula (1990-1992), Pontiac Firebird Trans Am (1990-1992), and Pontiac Firebird Trans Am GTA (1990-1992).
