GM 7.5-Inch 3.08 Posi-Traction Differential Carrier Assembly

The Zumbrota Drivetrain RAA435-2099U-P is a remanufactured complete axle assembly engineered for 1998-2003 Chevrolet S10 and GMC Sonoma models with the GM 7.5-inch ring gear. This assembly features a 3.08 gear ratio and includes Posi-Traction (G80) for enhanced traction. This specific axle assembly is designed for applications without the ZQ8 sport package or a third shock absorber. It is important to note that this unit does not include hubs, brakes, backing plates, or axle shafts, which may need to be sourced separately. Zumbrota Drivetrain rebuilds each axle assembly to stringent quality standards. This process involves a comprehensive inspection of the housing for straightness, cracks, and surface wear. All internal components, including the ring and pinions, internal gears, clutches, and carriers, undergo thorough inspection and testing. To ensure reliability and longevity, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The gears are inspected for optimal tooth contact patterns and correct rolling torque using inch-pound measurements for precise setup. Furthermore, Zumbrota utilizes an exclusive hydro-blast rinse and sandblasting procedure, followed by a proprietary shot-peening deep cleaning process on internal and external parts. This meticulous cleaning process restores housings to an OEM finish and meets OEM specifications for straightness. Correct gear backlash is set to ensure proper gear lubrication and quiet operation, setting a high standard for axle assembly remanufacturing.
