8.8-inch Rear Axle Assembly w/ 3.08 Ratio

The Zumbrota Drivetrain RAA435-276D is a remanufactured 8.8-inch rear axle assembly specifically for the 2011-2014 Ford Mustang equipped with the 3.7L engine. This assembly features an 8-bolt pinion flange and a clutch-style Posi-Traction differential for enhanced performance. This unit is built with a 3.08 gear ratio, but is specified as a 2.73 ratio due to Ring and Pinion availability. During the remanufacturing process, all bearings, seals, crush sleeves, pinion nuts, and shims are replaced, ensuring the integrity and longevity of the assembly. The housing is meticulously cleaned using a state-of-the-art hydro blasting and rinsing process to achieve an OEM finish, and is rigorously tested for surface wear and cracks. Furthermore, all tubes are inspected to ensure they are straightened to OEM specifications. Zumbrota Drivetrain establishes correct rolling torque using inch-pound measurements for precision setup and longevity. They also perform a 100% inspection of all internal parts, including the Ring & Pinion, internal gears, clutches, and carriers. This rear axle assembly does not include hubs, brakes, backing plates, or axle shafts.
