7.5" Mustang 3.27 Posi Limited Slip Axle Assembly

The Zumbrota RAA435-1961C-P is a remanufactured axle assembly engineered specifically for the 1999-2004 Ford Mustang, including the GT, SVT Cobra, and Mach 1 models. This unit is built around a Ford 7.5-inch ring gear and features a 3.27 gear ratio for optimal performance. The axle is a semi-floating type and includes the differential cover, but does not include hubs, brakes, backing plates, or axle shafts. Zumbrota Drivetrain prioritizes precision and reliability in their remanufacturing process. Each axle assembly undergoes a comprehensive inspection for straightness, cracks, and surface wear. All internal components, including ring and pinions, internal gears, clutches, and carriers, are thoroughly inspected and tested. To ensure longevity and quiet operation, all bearings and seals are replaced, and gears are set for optimal tooth contact patterns and correct rolling torque using precise inch-pound measurements. Gear backlash is carefully set to guarantee proper lubrication and smooth function. The remanufacturing process involves an exclusive hydro-blast rinse and sandblasting procedure on both internal and external parts, followed by a proprietary shot-enticed deep cleaning method, setting a high standard for axle assembly remanufacturing.
