GM 8.5-Inch Rear Axle Assembly Posi Limited Slip

The Zumbrota Drivetrain RAA435-2062-P is a remanufactured axle assembly specifically designed for the GM 8.5-inch rear end, featuring a 3.73 gear ratio and a Posi Limited Slip Differential. This unit is built to be a direct replacement for 1994-1997 Chevy S10 and S15 ZR2 models, ensuring a precise fit for enhanced performance and reliability. Zumbrota Drivetrain's remanufacturing process adheres to stringent quality standards. Each axle assembly is meticulously inspected for structural integrity, including checks for straightness, cracks, and surface wear. Internally, all components such as ring and pinions, gears, clutches, and carriers are subjected to comprehensive inspection and testing. To guarantee longevity and optimal performance, all bearings and seals are replaced, and gears are precisely set for tooth contact patterns and rolling torque using inch-pound measurements. Proper gear backlash is carefully set to ensure quiet operation and effective gear lubrication. Furthermore, axle tubes are verified to meet OEM specifications for straightness. The remanufacturing process includes a specialized hydro-blast rinse and sandblasting procedure for both internal and external parts, followed by a proprietary shot-peening deep cleaning. This extensive cleaning process restores housings to an OEM finish, setting a high standard for remanufactured axle assemblies. The assembly includes a cover, but does not include fluid. The axle type is semi-floating.
