About This 2025 GMC Sierra
Our diesel-driven One Owner and Clean Carfax 2025 GMC Sierra 3500 AT4 Crew Cab 4X4 with the Premium Plus Package is where Pro Grade capability meets premium comfort in Sterling Metallic! Motivated by a TurboCharged 6.6 Liter DuraMax Diesel V8 offering 470hp and 975lb-ft of torque to a 10 Speed Allison Automatic transmission for getting to work where the pavement ends. This Four Wheel Drive truck also boasts an off-road suspension with hill-descent control and a 2-speed transfer to help handle difficult terrain with calm confidence. Advanced style and functionality come into the picture with our Sierra's LED lighting, protective skid plates, MultiPro tailgate, 20-inch alloy wheels, spray-on bedliner, power-folding trailer mirrors, a sunroof, and a receiver hitch with wiring harness.
Our AT4 cabin is outfitted for severe duty with heated/ventilated leather power front and heated rear seats, a heated-wrapped steering wheel, dual-zone automatic climate control, and remote start. Those impressive luxuries complement sophisticated technologies, too: A 13.4-inch touchscreen, 12.3-inch driver display, Google Built-In, wireless Apple CarPlay®/Android Auto®, WiFi compatibility, Bluetooth®, and Bose audio are all standard!
Staying safe is mandatory, so GMC ensures you're well-protected by HD surround vision, automatic braking, trailer-capable blind-spot monitoring, lane-departure warning, hitch view/guidance, hill-start assistance, trailer sway control, and more. A mighty workhorse, our Sierra 3500 AT4 is made to do better! Save this Page and Call for Availability. We Know You Will Enjoy Your Halladay Motors Test Drive Towards Ownership!
