The Titan PRO-4X model offers more off-road features, including Rancho performance shock absorbers, a lower final drive ratio (to 3.357), additional skid plates on the oil pan and transfer case, an Electronic Locking Rear Differential and 18-inch aluminum-alloy off-road wheels mounted with P275/70R18 all-terrain tires.
PRO-4X meters and gauges are styled differently and seats have an embroidered PRO-4X logo, red stitching. A red-stitched shift knob and steering wheel are available.
All PRO-4Xs have a body-colored grille and bumper and the decal you see in the photo above.
