The Pro is the most configurable trim in the lineup, available in regular cab, double cab, and crew cab with multiple bed lengths — making it the go-to choice for fleet buyers and contractors. The SLE introduces the larger 13.4-inch display and heated features that make it one of the most popular choices for daily drivers in Midlothian and Ennis who want comfort without stepping into premium pricing. The Elevation adds visual distinction with its blacked-out styling, while the SLT marks the transition to V8 power and leather as standard equipment.
For off-road capability, the AT4 comes standard with the Duramax turbo-diesel engine alongside a 2-inch factory lift, skid plates, and an electronic locking rear differential. The AT4X builds on that foundation with Multimatic DSSV dampers — exclusive to this trim — and front and rear electronic locking differentials for maximum traction on demanding terrain. Both AT4 trims are available in Crew Cab 4WD only.
At the top of the lineup, the Denali offers a premium experience with the 5.3L V8 standard and the option to upgrade to the 6.2L V8 or Duramax diesel. The Denali Ultimate is the flagship, pairing the standard 6.2L V8 with Super Cruise hands-free driving technology, massaging seats, and exclusive interior appointments.

Four powertrains are available across the Sierra 1500 lineup, each paired with either an 8-speed or 10-speed automatic transmission. All engines are available with rear-wheel drive or four-wheel drive (4WD is standard on AT4 and AT4X).
