2023 GMC Sierra 1500

2023 GMC Sierra 1500 AT4X Crew Cab 4WD | 6.2L V8 Power, Multimatic DSSV Suspension, and Ultimate Off-Road Luxury

If you’re searching for a used GMC Sierra AT4X for sale in Ontario, a premium off-road truck near Bancroft, a luxury 4x4 pickup with front and rear locking differentials, or one of the most capable half-ton trucks GMC has ever built, this 2023 Sierra 1500 AT4X stands at the top of the market.

Finished in Onyx Black with the exclusive Obsidian Rush full-grain leather interior, this AT4X combines serious off-road capability with luxury features normally reserved for premium SUVs. Under the hood is the powerful 6.2L EcoTec3 V8 engine paired with a 10-speed automatic transmission, delivering impressive towing capability, effortless highway performance, and the unmistakable sound and power truck enthusiasts are looking for.

What separates the AT4X from other Sierra models is its factory-engineered off-road hardware. Equipped with Multimatic DSSV dampers, a factory 2-inch lift, front and rear electronic locking differentials, skid plates, hill descent control, mud-terrain Goodyear Wrangler Territory MT tires, and an advanced 2-speed Autotrac transfer case, this truck is designed to tackle terrain that most pickups simply cannot.

Truck buyers searching for premium off-road trucks often compare the AT4X against the Silverado ZR2, Ford Raptor, and Ram Rebel. The Sierra AT4X delivers exceptional capability while maintaining GMC’s signature luxury and refinement.

Inside, the cabin feels more like a luxury SUV than a pickup truck. Features include full-grain leather seating, heated and ventilated front seats, heated rear outboard seats, 16-way power massage front seats, memory seating, dual-zone climate control, wireless charging, a power sunroof, premium floor liners, and a power-adjustable steering column.

Technology is among the strongest in the segment. The massive 13.4-inch touchscreen includes Google Built-In, wireless Apple CarPlay, wireless Android Auto, navigation capability, an in-vehicle trailering app, Wi-Fi hotspot capability, and a premium 12-speaker Bose sound system. Drivers also benefit from a 15-inch Head-Up Display, Rear Camera Mirror, and a fully digital 12.3-inch driver information centre.

For towing and hauling, the AT4X includes a factory trailering package, integrated trailer brake controller, trailer side blind zone alert, bed-view camera, HD Surround Vision, and GMC’s innovative MultiPro Tailgate with integrated Kicker MultiPro Audio System.

Safety remains a major selling point with Adaptive Cruise Control, Automatic Emergency Braking, Forward Collision Alert, Lane Keep Assist, Rear Cross Traffic Braking, Rear Pedestrian Alert, Front and Rear Park Assist, Safety Alert Seat, HD Surround Vision, and Trailer Side Blind Zone Alert.

Adding even more exclusivity, this truck is equipped with a dealer-installed Cat-Back Performance Exhaust System and Sport Steps, enhancing both appearance and sound.

For buyers seeking one of the most capable, luxurious, and desirable GMC trucks available, this Sierra AT4X represents the pinnacle of premium off-road performance.
