SLT

5.3L V8 engine · 10-speed automatic transmission · Chrome grille · Power front outboard seats

The SLT trim is where the Sierra 1500 begins to feel distinctly premium while staying focused on real truck utility. Its standard 5.3L V8 engine pairs with a 10-speed automatic transmission, giving drivers confident acceleration, relaxed cruising, and the kind of proven power many pickup owners prefer. Chrome details on the grille, door handles, and front and rear bumpers add a polished look, while 10-way power front outboard seats with power lumbar improve comfort for both the driver and front passenger. SLT also offers the available Duramax 3.0L Turbo-Diesel engine, ProGrade® Trailering System, and chrome wheel-to-wheel assist steps, making it especially appealing for shoppers who want easier trailering and easier cabin access. Inside, perforated leather appointments help create a more refined environment without compromising the truck’s practical attitude.

AT4

Duramax 3.0L Turbo-Diesel engine · 2" factory lift · Rancho® monotube shocks · Underbody skid plates

The AT4 trim is built for drivers who want confident off-road capability directly from the factory. It adds the Duramax 3.0L Turbo-Diesel engine with 10-speed automatic transmission, a 2" factory lift, off-road suspension, Rancho® monotube shocks, a two-speed Autotrac® transfer case, and underbody skid plates. Those upgrades make the AT4 well suited for unpaved access roads, trail approaches, rural properties, boat launches, and uneven terrain where additional clearance and control matter. Hill Descent Control helps manage steep declines, while the unique Jet Black interior with Kalahari accents and heated and ventilated perforated front leather seating surfaces gives the cabin a rugged but comfortable feel. Available features such as the 15" diagonal multicolor Head-Up Display and 6.2L V8 engine add even more appeal for drivers who want enhanced visibility or stronger gas-engine performance. AT4 is a strong pick for shoppers who need a truck that works during the week and feels ready for adventure afterward.
