7.5-Inch Rear Axle Assembly 3.42 G80 Posi Traction

The Zumbrota Drivetrain RAA435-2110CE-P is a remanufactured axle assembly built to rigorous standards for precision and reliability. It features a GM 7.6-inch ring gear with a 3.42 gear ratio and G80 Posi Traction, identified by the GU4 ratio option. This assembly is specifically designed for 1983-1991 Chevrolet S10, S15, Blazer, GMC Jimmy, and Sonoma 4WD vehicles. Each axle assembly undergoes thorough inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, gears, clutches, and carriers, are fully inspected and tested. New bearings, seals, crush sleeves, pinion nuts, and shims are installed. Gears are meticulously inspected for optimal tooth contact patterns and correct rolling torque, measured in inch-pounds for precise setup and longevity. Gear backlash is set to ensure proper lubrication and quiet operation, and axle tubes are checked for OEM standards of straightness. Zumbrota Drivetrain employs an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-enticed deep cleaning process for internal and external parts. This ensures a high standard of remanufacturing. Please note that this assembly does not include hubs, brakes, backing plates, or axle shafts.
