2014 Nissan Titan King Cab 4X4 PRO-4X Review - Automoblog.net (blog)

But this pickup comes with wider all-terrain tires (275/70R18), off-road suspension tuning, 3. 36:1 axle gears, electronic locking rear differential, skid plates that protect the oil pan, fuel tank, transfer case and lower radiator. A few extras make the Titan a perfect vehicle for off-road adventures. Titan’s off-road capability is enhanced with its shift-on-the-fly 4-wheel drive. The system allows the driver to shift between 2WD and 4WD instantaneously while driving up to 60 mph. We did this on the highway to check it out, and the system was seamless in shifting between two-wheel and four-wheel-drive. 4WD also includes a low-range 4-LO, for severe off-road conditions where control is needed at very low speeds for climbing or descending steep terrain. PRO-4X also comes with an electronic locking rear differential that works with the flip of a switch. The off-road feature enables the vehicle to send power to both rear wheels equally to boost grip in demanding situations. We tested the 4WD system out on a trail west of Denver between Evergreen and Idaho Springs. It was easy to switch the locking rear differential on with the interior switch. Source: www.automoblog.net
