Description

The Zumbrota Drivetrain RAA435-1510C is a remanufactured complete rear axle assembly meticulously rebuilt for 1988-1999 GMC 1500 pickup trucks with 2WD. This assembly is built to high standards of precision and reliability, featuring an 8.5-inch GM 10-bolt ring gear with a 3.42 gear ratio. It is designed without posi-traction and explicitly does not include hubs, brakes, backing plates, or axle shafts. All internal components, including ring and pinions, gears, clutches, and carriers, are thoroughly inspected and tested. Zumbrota replaces all bearings and seals, meticulously inspecting gears for optimal tooth contact patterns and correct rolling torque. Axle tubes are checked for OEM standards of straightness, and the assembly undergoes a proprietary cleaning procedure. This rear axle assembly is compatible with 1988-1999 Chevrolet C1500 models (4.3L, 5.0L, 5.7L, and 6.2L engines) and 1988-1999 GMC 1500 pickup trucks.
