The X31 off-road suspension with a factory 2-inch lift, skid plates, hill descent control, and Goodyear DuraTrac tires give it real off-road capability without sacrificing on-road comfort. The V8 delivers strong, immediate power for towing, passing, or highway driving, and the 10-speed transmission keeps it smooth and responsive in all conditions.Inside, the AT4 cabin blends rugged design with real luxury. Heated and ventilated front seats, heated rear seats, a heated steering wheel, dual-zone climate control, and premium materials make long drives and daily use comfortable. The Technology Package adds features you'll actually use, like the head-up display and surround view cameras, which make towing, parking, and trailering noticeably easier. The MultiPro tailgate, spray-on bedliner with AT4 logo, and power sliding rear window add everyday utility.Safety and driver assistance are another strong point.
