Powering the Sierra SLT is a 5.3-liter EcoTec3 V8 engine, paired with a 10-speed automatic transmission. The drivetrain includes an Auto-Locking Rear Differential and an Off-Road Suspension setup, part of the X31 Off-Road Package, which also adds Hill Descent Control, front recovery hooks, and skid plates for underbody protection. The integrated trailer brake controller, ProGrade Trailering System, Hitch Guidance with Hitch View, and Trailer Side Blind Zone Alert collectively enhance towing capability, while Trailer Camera Provisions offer added visibility for safe maneuvering.

This SLT model delivers an upscale cabin trimmed in Jet Black leather, with front bucket seats, ventilated front seats, and heated second-row outboard seats.

The Sierra 1500 SLT includes an array of USB ports across the cabin, a 120-volt power outlet in the bed, and another in the cabin for added functionality. All-weather floor liners protect the interior from dirt and debris, while deep-tinted glass and perimeter lighting improve both privacy and nighttime visibility. Chrome accents on the grille and assist steps add visual presence, and 20-inch polished aluminum wheels support both style and substance.

For safety, this truck features HD Surround Vision, a HD Rear Vision Camera, Rear Cross Traffic Braking, Rear Pedestrian Detection, Ultrasonic Front and Rear Park Assist, and a Safety Alert Seat.
