Overview

Ready to make a bold statement, our Diesel driven 2025 GMC Sierra 3500 AT4 Crew Cab 4X4 is where Pro Grade capability meets premium comfort in Onyx Black! 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, and a receiver hitch with wiring harness.

You are going to love our AT4 cabin, which 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 Test Drive Towards Ownership!
