Axle Assembly 3.73 Ratio G80 Posi-Traction

The Zumbrota Drivetrain RAA435-1510D is a remanufactured complete axle assembly designed for 1988-1999 GMC 1500 Pickup trucks with 2WD drivelines. This assembly features a 3.73 gear ratio and includes a G80 Posi-Traction differential for enhanced performance. The unit is built upon a GM 8.5-inch ring gear with a GT4 ratio option. Zumbrota Drivetrain Axle Assemblies are meticulously rebuilt to high standards of precision and reliability. Each 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. To ensure longevity and proper function, all bearings and seals are replaced, and gears are set for optimal tooth contact patterns and correct rolling torque using inch-pound measurements. The axle tubes are inspected to ensure they meet OEM standards for straightness. Zumbrota employs an exclusive hydro-blast rinse and sandblasting procedure for internal and external parts, followed by a proprietary shot-peened deep cleaning process, setting a high standard for axle assembly remanufacturing. The product notes specify that this assembly does not include hubs, brakes, backing plates, or axle shafts, and these components will need to be sourced separately.
