Ford 8.8 Rear Axle Assembly 3.55 Posi Traction

The Zumbrota Drivetrain RAA435-2034D-P is a remanufactured complete axle assembly engineered for durability and performance, specifically designed for Ford 8.8-inch rear ends. This axle assembly features a 3.55 gear ratio and a Posi Traction (Limited Slip Differential) for improved traction and handling. It is built for Ford F150 models from 1997 to 2000, specifically those equipped with rear disc brakes. The unit is identified by tag numbers S869A, S869B, and S869C, ensuring precise compatibility. Please note that this assembly is sold without hubs, brakes, backing plates, or axle shafts, requiring these components to be sourced separately. Zumbrota Drivetrain emphasizes rigorous quality control in their remanufacturing process. Each axle assembly undergoes thorough inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, internal gears, clutches, and carriers, are 100% inspected and tested. Crucially, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced with new parts. The gear setup involves inspecting for optimal tooth contact patterns and establishing correct rolling torque using inch-pound measurements for precision, longevity, and quiet operation. The housings are meticulously cleaned using an exclusive hydro-blast and rinsing process, returning them to an OEM finish.
