Differential Ring and Pinion

The Ford 9-inch rear end is a highly popular and robust drivetrain component used in original production cars and trucks, as well as performance and race vehicles from 1957 through 1986. This differential is designed for a 28-spline Ford 9-inch axle. The 6.00 gear ratio is an aggressive aftermarket option, commonly used for racing applications, providing increased torque at the expense of top-end speed. Identification of a Ford 9-inch typically involves the third member bolted to the front of the axle housing and the absence of a traditional rear housing cover. 28-spline axles were common in many early and lower-performance 9-inch applications.
