Up to 14 available camera views with HD Surround Vision enhance awareness when you’re picking through tight lines or backing to a trailer on uneven ground. Adaptive Cruise Control with trailering is available to help ease long-mile drives between sites. The MultiPro™ Tailgate and available 15-inch Head-Up Display with an off-road inclinometer further demonstrate the truck’s go-anywhere, work-anywhere mindset.

AT4X

Factory-lifted and fitted for rugged tasks and trails alike, AT4X is the most serious off-road expression in the lineup. A 1.5-inch factory suspension lift teams up with Multimatic® DSSV dampers and a rear electronic-locking differential to help keep traction coming and ride control precise over rocks, ruts, and washboard. Underbody armor includes a larger steel transfer case skid plate and a front aluminum skid plate. Massive 35-inch Goodyear® Territory MT tires provide the footprint you need on challenging two-tracks or loose worksite sections. Inside, AT4X surprises with an Obsidian Rush interior that features full-grain leather, technical-grain accents, authentic Vanta ash wood, and 16-way heated and ventilated power front seats with massage. For those who want a more specialized look and added protection, the available AT4X AEV Edition brings stamped steel bumpers, additional skid plates for the steering gear and transfer case, and 18-inch Salta gloss-black wheels. The available Duramax® 6.6L Turbo-Diesel remains the go-to for demanding tow assignments. AT4X is the choice for owners who want the most advanced off-road hardware in a heavy-duty package, with a cabin that feels first-class between job bids or trailheads.
