14 Bolt Rear Axle Assembly w/ 3.42 Posi Limited Slip

The Zumbrota Drivetrain RAA435-1653A-P is a remanufactured complete rear axle assembly engineered as a direct replacement for 1990-2000 GM 3500 series trucks. This axle assembly is built to order and features a 3.42 gear ratio with a Posi Limited Slip Differential (LSD). During the remanufacturing process, Zumbrota Drivetrain ensures all tubes are inspected and straightened to OEM specifications, and housings undergo rigorous testing for surface wear and cracks. Internal components, including the ring and pinion, gears, clutches, and carriers, are subjected to a 100% inspection. All necessary wear items such as bearings, seals, crush sleeves, pinion nuts, and shims are replaced. The housing is then cleaned using a hydro blasting and rinsing process to restore it to an OEM finish. The correct rolling torque is established using inch-pound measurements to ensure precision setup and longevity. This remanufactured axle assembly is built to the exact specifications required for optimal performance and durability in the specified GM trucks.
