Description

The Zumbrota Drivetrain RAA435-276C is a remanufactured 8.8" rear axle assembly specifically built for the 2011-2014 Ford Mustang equipped with the 5.0L engine. This unit comes with a 3.73 gear ratio and a 6-bolt cup style pinion yoke, offering a precise setup for your Mustang's drivetrain. This assembly is not equipped with Posi Traction. It is important to note that this rear axle assembly does not include hubs, brakes, backing plates, or axle shafts. Each component is meticulously prepared; housings are hydro-blasted to an OEM finish, and all internal parts, including ring and pinion gears, are 100% inspected. Zumbrota Drivetrain ensures longevity by using 100% new bearings, seals, crush sleeves, pinion nuts, and shims, with rolling torque established using precise inch-pound measurements for optimal setup and durability. Housings are also inspected for surface wear and cracks, and tubes are straightened to OEM specifications.
