Eastern Washington is an off-roader’s backyard. Eastern Washington is an off-roader’s backyard. Canyon trails outside Yakima are just the beginning. The Horse Heaven Hills, Columbia River Gorge ridgelines, and Blue Mountain forest roads all deliver serious adventure. And when it comes to GMC off-road capability, no trim delivers more than the AT4 and AT4X. Here’s a breakdown of the best GMC trucks for off-road use — and what each GMC off-road package actually gives you.
GMC Canyon AT4 & AT4X Best Mid-Size Off-Roader
Mid-Size Pickup · 4WD Standard · 310 HP TurboMax · 430 lb-ft Torque
Ground Clearance: 9.6″ (AT4) · 11.6″ (AT4X ) Factory Lift: 2″ (AT4) · 3″ (AT4X) Max Towing: 7,700 lbs
The Canyon AT4 is GMC’s most nimble off-road truck. It’s compact enough to tackle tighter trails without sacrificing factory hardware. The standard AT4 comes with a 2″ suspension lift and 9.6″ of ground clearance. All-terrain tires, skid plates, and Hill Descent Control come standard. It also includes a two-speed Autotrac transfer case and automatic locking rear differential. Four drive modes are available — Terrain, Off-Road, Normal, and Tow-Haul
Step up to the Canyon AT4X Package and the GMC off-road package gets significantly more serious — a 3″ lift with Multimatic jounce control dampers, LT285/70R17C mud-terrain tires, front and rear electronic locking differentials, underbody cameras, and rocker panel protection. The top-of-the-line AT4X AEV Edition adds American Expedition Vehicles-engineered stamped steel bumpers, five boron steel skid plates, and beadlock-capable wheels with LT315/70R17 mud-terrain tires.
- ✓Factory lift, skid plates, and locking rear differential standard on AT4
- ✓Baja mode on AT4X for high-speed desert driving
- ✓Real-time off-road performance data on 11.3″ touchscreen
- ✓Up to 10 camera views for tight trail navigation
- ✓Hill Descent Control for steep, uneven terrain
- ✓First-in-class integrated tailgate storage with drain — perfect for trail gear
“The Canyon AT4X is my pick. It’s the perfect size for hitting trails around Eastern Washington — you can get into spots a full-size truck can’t, and it’s still loaded with serious off-road hardware right from the factory. The mud-terrain tires and locking diffs make a huge difference on the terrain out here.”
— Alfonso, Sales
“I always tell customers to look at either the Canyon AT4X or the Sierra 1500 AT4X depending on what they need. If you want a more maneuverable truck for tighter trails, the Canyon AT4X is incredible. If you need full-size space and towing, the Sierra 1500 AT4X is the move. Both are genuinely capable right out of the box — no aftermarket upgrades needed.”
— Rafael, Sales
Best for: Trail riders, overlanders, and Tri-Cities drivers who want a nimble, capable off-road truck for backcountry adventures without giving up daily drivability.

The AT4 comes standard with a 2″ suspension lift, 33″ Goodyear Wrangler Territory mud-terrain tires, Hill Descent Control, red recovery hooks, skid plates, and a push-button 4WD system.

“If I’m recommending one truck for off-road use in the Tri-Cities, it’s the AT4X. The Sierra 1500 AT4X especially — it has the full-size capability you need for towing your toys to the trailhead, and then the suspension and locking diffs to actually handle what you find out there. It’s the complete package.”
— Arthur, Sales
Best for: Tri-Cities drivers who need a full-size daily driver and tow vehicle but want factory off-road capability for weekend trail runs, hunting access roads, and backcountry camping.
GMC Sierra 2500 HD AT4 & AT4X
Full-Size Heavy-Duty · 4WD Standard · Gas V8 or Duramax 6.6L Diesel
AT4X Ground Clearance: 11.6″ AT4X Tires: 35″ Goodyear Territory MT Max Towing: Up to 20,000 lbs (diesel)

The AT4X adds Multimatic DSSV dampers, 35″ Goodyear Territory MT tires, 11.6″ of ground clearance, a 31.6° approach angle, and a rear electronic locking differential.
