Dealer notes
This 2026 GMC Sierra 1500 AT4 crew cab 4WD is a new unit currently in transit, arriving soon at Napleton Chevrolet Buick GMC in Beaver Dam. It is finished in Sterling Metallic — a cool, medium metallic silver — over a Jet Black with Kalahari Accents interior trimmed in perforated leather, and it is built around the one powertrain that sets it apart from every gasoline Sierra AT4 on the market: the Duramax 3.0L turbo-diesel inline-six paired with a 10-speed automatic transmission with Electronic Precision Shift.
At a glance: Duramax 3.0L turbo-diesel inline-six · 10-speed automatic with Electronic Precision Shift · 4WD with 2-speed transfer case · crew cab / short bed · in transit, arriving soon · Sterling Metallic exterior / Jet Black with Kalahari Accents perforated leather interior

The diesel engine is the defining choice here, and the build compounds it with everything the AT4 grade adds for off-road and towing work. Off-road hardware includes an off-road suspension, skid plates, a heavy-duty air filter, red recovery hooks, and 20-inch machined aluminum wheels with carbon grey accents riding on 275/60R20 all-terrain tires — plus dealer-installed off-road high-clearance steps from the AT4 Premium Package.
The auto-locking rear differential and hill descent control give the 4WD system real capability on loose or steep terrain, and the integrated trailer brake controller, trailering package, in-vehicle trailering system app, HD Surround Vision, hitch view, trailer camera provisions, and trailer side blind zone alert make this one of the most completely equipped towing setups in the Sierra lineup.
Inside, the Technology Package adds a multicolor 15-inch diagonal head-up display, a rear camera mirror with inside rearview auto-dimming, and a bed view camera — all working alongside the 13.4-inch diagonal premium GMC Infotainment System with Google Built-In apps including navigation and voice assistance, wireless Apple CarPlay and Android Auto, and a Bose 7-speaker premium sound system. The Preferred Equipment Group 4SB brings ventilated and heated front bucket seats, heated second-row outboard seats, wireless charging, a remote vehicle starter system, keyless open and start, a spray-on pickup bedliner with GMC logo, rear wheelhouse liners, front premium floor liners with removable carpet insert, and a 120-volt interior power outlet.
The AT4 Preferred Package adds a power sliding rear window with rear defogger and a universal home remote. Driver assistance is handled by GMC Pro Safety — forward collision mitigation, rear cross traffic braking, rear pedestrian detection, and ultrasonic front and rear park assist — along with perimeter lighting and an engine block heater for Wisconsin winters.
We are located at N8167 Kellom Rd. in Beaver Dam, about 45 minutes from Madison, an hour from Milwaukee, and 35 minutes from Fond du Lac — serving shoppers from Mayville, Watertown, Columbus, and Randolph. Napleton Chevrolet Buick GMC has been family-owned for more than 80 years, and we work hard to keep the process straightforward and pressure-free.
If the diesel Sierra AT4 is the direction you are headed, we can get you the details on this build and its arrival timeline now.
