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.
According to Kelley Blue Book and Edmunds, the Duramax 3.0L diesel is the Sierra lineup's efficiency champion, delivering strong towing torque with fuel economy no gas half-ton can match. The SLT with X31 is a smart spec for buyers who work their trucks and drive real distances.
