Listing Notes
Dominance meets diesel efficiency in Central Texas. This 2026 GMC Sierra 1500 AT4 in a commanding Onyx Black is the ultimate factory-lifted pickup. Available now at Bruner Auto Group, this truck is engineered for those who demand serious off-road capability without sacrificing fuel economy or high-end luxury. Whether you're crossing ranch land in Brown County or heading out to Lake Brownwood, the AT4 is built to lead the way.
Duramax Diesel Power & Off-Road Prowess:
Under the hood is the highly acclaimed 3.0L I6 Duramax Turbo-Diesel engine, delivering a massive 495 lb-ft of torque. Paired with a precision 10-speed automatic transmission, this AT4 offers the perfect combination of low-end grunt for towing and impressive highway efficiency (up to 26 MPG).
Factory-Lifted Performance: Features a 2-inch factory suspension lift and the X31 Off-Road Package with Rancho monotube shocks for superior ground clearance and ride quality.
4WD Command: Equipped with a 2-speed active transfer case, Auto-Locking Rear Differential, and Hill Descent Control to handle the toughest Texas terrain.
Bold Utility: Features signature Red Recovery Hooks, a high-capacity air filter, and a Dual Active Exhaust system.
Elite AT4 Interior & Technology:
The cabin is a masterclass in rugged luxury, featuring Jet Black leather with Kalahari accents and authentic technical finishes.
Command Center: Stay informed with a 13.4 diagonal GMC Infotainment System with Google built-in and a massive 15 Diagonal Multicolor Head-Up Display.
First-Class Comfort: Enjoy Heated and Ventilated front bucket seats, Heated second-row outboard seats, and a Heated Steering Wheel for those chilly Texas mornings.
Premium Sound: Experience your playlist like never before with the Bose Premium 7-Speaker Sound System.
Connectivity: Fully loaded with Wireless Apple CarPlay and Android Auto, Wireless Charging, and a Power Sunroof.
Unmatched Utility & Safety:
This Sierra is as functional as it is aggressive, featuring the world-first GMC MultiPro Tailgate with an integrated Kicker Audio System.
Bed Protection: Includes a factory Spray-on Pickup Bedliner with GMC Logo, LED Cargo Area Lighting, and 120-volt bed-mounted power.
Visibility Suite: Navigate trailers with ease using HD Surround Vision, Bed View Camera, and Trailer Side Blind Zone Alert.
