The AT4 is GMC's off-road-focused Sierra, and this one carries the hardware to back it up. Off-road suspension, skid plates, red recovery hooks, an auto-locking rear differential, hill descent control, and a 2-speed transfer case give it real-world capability on dirt or snow.
The 6.2L ECOTEC3 V8 — paired with a 10-speed automatic and active dual exhaust with sport mode — provides the motivation to match. Twenty-by-nine machined aluminum wheels wear 275/60R20 all-terrain tires, and the spray-on bed liner with GMC logo keeps the bed ready for work from day one.
Inside, the AT4 Premium Package, AT4 Preferred Package, Preferred Equipment Group 4SB, and Technology Package stack on comfort and technology across every drive. Front seats are heated and ventilated; second-row outboard seats are heated.
The power sunroof, power rake-and-telescoping steering column, and remote vehicle starter round out the daily-comfort story. On the technology side, the 13.4-inch GMC Infotainment System with Google built-in apps, wireless Apple CarPlay and Android Auto, a Bose 7-speaker sound system, wireless charging, and a SiriusXM with 360L trial subscription handle connectivity.
The multicolor 15-inch diagonal head-up display, rear camera mirror, and bed view camera come via the Technology Package. A power sliding rear window with rear defogger and universal home remote arrive through the AT4 Preferred Package.
The trailering story is equally thorough: the Trailering Package, integrated trailer brake controller, In-Vehicle Trailering System app, HD Surround Vision, hitch view, trailer side blind zone alert, trailer camera provisions, and an auxiliary external transmission oil cooler are all in place. Driver-assistance features include forward collision mitigation, rear pedestrian detection, rear cross traffic braking, ultrasonic front and rear park assist, and GMC Pro Safety.
A heavy-duty air filter and external engine oil cooler round out the working-truck spec.
Napleton Buick GMC is at 6305 Northwest Hwy in Crystal Lake, on US-14 close to the Metra UP-NW line and convenient for drivers coming from Lake in the Hills, Huntley, McHenry, and Woodstock.
