2026 GMC Sierra 1500

The Sierra 1500 lineup begins with the Pro, which is a work-focused truck powered by the standard TurboMax© engine and equipped with durable materials for daily productivity. Moving up, the SLE introduces greater refinement with a 13.4-inch GMC Premium Infotainment System, a 12.3-inch Driver Information Center, heated front seats, and an automatic locking rear differential. The Elevation brings a more athletic personality through monochromatic styling, gloss-black exterior accents, and 20-inch wheels, while the SLT adds chrome detailing, leather-appointed seating, and access to the 5.3 L EcoTec3© V8. The AT4 is engineered for off-road exploration with a factory 2-inch suspension lift, Rancho© monotube shocks, skid plates, and available Duramax© 3.0 L Turbo-Diesel power. Taking things further, the AT4X builds on that capability with Multimatic© DSSV dampers, front and rear electronic locking differentials, and available American Expedition Vehicles© equipment.
