Remanufactured Rear Axle Assembly 8.5-Inch 30 Spline 3.73 G80

The Zumbrota Drivetrain Reman Axle Assy is a comprehensively rebuilt rear axle assembly designed for 1988-1999 GM 1500 4WD trucks. This unit is equipped with a 3.73 gear ratio, 30 spline axles, and the G80 Posi Traction system for enhanced performance. Each Zumbrota axle assembly undergoes rigorous inspection and rebuilding processes. This includes thorough checks for straightness, cracks, and surface wear on the housing and tubes. Internal components such as ring and pinions, gears, clutches, and carriers are fully inspected and tested. All bearings and seals are replaced, and gears are set up with precise backlash and rolling torque measurements for optimal setup, longevity, and quiet operation. The housings are cleaned using a hydro-blast rinse and sandblasting procedure, followed by a deep cleaning process. This specific assembly is for an 8.5-inch GM 10-bolt axle and is compatible with 30 spline axles. It is important to note that this product does not include hubs, brakes, backing plates, or axle shafts, which will need to be sourced separately if not already present or reusable. The Zumbrota Drivetrain Reman Axle Assembly comes with a 2-year limited warranty.
