Diesel torque with SLT refinement — this 2026 GMC Sierra 1500 SLT Crew Cab 4WD runs the Duramax 3.0L Turbo-Diesel through a 10-speed automatic and wears the X31 Off-Road and Protection Package. Sterling Metallic over Jet Black with ventilated front seats and 20-inch polished aluminum wheels, it's built to tow all day and sip fuel doing it — an ideal fit for long South Dakota highway miles.

The SLT Premium Package loads it further, and the X31 package adds off-road suspension, skid plates, all-terrain tires, and a heavy-duty air filter for the gravel. The GMC MultiPro tailgate, HD rear vision camera, and trailering package with storage handle the work side.
