Description

The Zumbrota Drivetrain RAA435-2036C-P is a remanufactured complete rear axle assembly designed for specific Ford F-150 models from 1999-2000. This unit is built around a robust 8.8-inch Ford ring gear and boasts a 3.31 gear ratio, optimized for a balance of acceleration and highway cruising. This axle assembly features a Posi-traction (Limited Slip Differential) system, enhancing traction and performance, especially during acceleration and cornering. It is specifically configured for rear drum brake systems and includes the tag number S826A. The assembly is manufactured to OEM specifications, with tubes inspected for straightness and housings tested for surface wear and cracks, ensuring quality and reliability. It is important to note that this assembly does not include hubs, brakes, or axle shafts, which may need to be sourced separately. Compatibility is confirmed for 1999-2000 Ford F-150 models equipped with the 8.8-inch rear axle, 3.31 ratio, and rear drum brakes.
