An electronic locking rear differential has been standard on the FX4 off-road model since 2009, which is when the F-150 was last redesigned. Previous versions had a limited-slip differential. Among other standard features are four-wheel drive, hill descent control, skid plates and 18-inch wheels.


More information on the FX4 and other F-150 models can be found in the Research section, here.
