2023 GMC Terrain Exterior Feature Highlights

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. GMC Sierra 1500 AT4 & AT4X Best Full-Size Off-Roader Full-Size Half-Ton · 4WD Standard · 5.3L V8 · 6.2L V8 · or 3.0L Duramax Diesel Factory Lift: 2" Tires: 33" Goodyear Wrangler Territory MT Max Towing: Up to 13,200 lbs The Sierra 1500 AT4 gives you full-size truck capability — more cargo bed space, higher payload, and towing up to 13,200 lbs — wrapped in GMC's best off-road package for a half-ton. 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. The AT4X steps things up with Multimatic DSSV dampers, front and rear electronic locking differentials, rocker panel protection, and the AEV Edition adds stamped steel bumpers with front winch capability. ✓2" factory lift with 33" Goodyear MT tires standard on AT4 ✓Available Duramax 3.0L Turbo-Diesel for maximum trail-day range ✓Hill Descent Control and red recovery hooks standard ✓AT4X: Multimatic DSSV dampers and front/rear electronic locking differentials ✓AEV Edition: front winch capability and boron steel skid plates ✓Up to 14 camera views for trail and trailering visibility ✓MultiPro Tailgate — six functions for trailhead loading and unloading "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) For Tri-Cities drivers who need heavy-duty towing and payload alongside serious GMC off-road capability, the Sierra 2500 HD AT4 is the answer. The AT4 brings twin-tube Rancho shocks, skid plates, and Hill Descent Control. 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. If your off-road use involves towing a horse trailer or equipment down rough ranch roads, nothing does it better. Best for: Contractors, ranchers, and drivers who regularly tow heavy loads and still need to access rough terrain — the HD AT4 is the best of both worlds. Come see the AT4 lineup in person.

If you've been searching for a great deal on a new GMC Sierra in the Tri-Cities, WA, you're in the right place. At Speck Buick GMC, we work hard to make sure every customer drives away with a payment that fits their budget , whether you're leasing, financing, or somewhere in between. Here's everything you need to know about GMC Sierra monthly payments in the Tri-Cities, WA and how to find the right deal for you. What Affects Your GMC Sierra Monthly Payment? No two Sierra payments are exactly the same and that's a good thing. Your monthly payment is shaped by several key factors, and understanding them puts you in control before you ever sit down with our finance team. Money Down The more you put down upfront, the lower your monthly payment. Even a modest down payment of $3,000–$5,000 can make a meaningful difference in your monthly commitment, especially when combined with a competitive GMC financing rate. More down simply means less to finance each month. Rebates & Incentives GMC consistently offers manufacturer rebates and incentives on the Sierra lineup and these can significantly reduce the amount you're financing. Rebates are applied directly to the purchase price, lowering your payment before you even factor in a down payment or trade. Available rebates change monthly, so it always pays to check what's currently on the table. Trade-In Value Have a vehicle to trade? Your trade-in value works just like a down payment, reducing the amount you're financing and brings your monthly payment down. Even an older, higher-mileage truck can carry meaningful trade equity. Our team will give you a straightforward appraisal and apply every dollar toward your new Sierra. Lease vs. Finance — Which Payment Is Lower? Here's something many Sierra shoppers don't realize: a GMC Sierra lease payment in the Tri-Cities, WA is often significantly lower than a finance payment on the same truck. That's because with a lease, you're only paying for the portion of the truck's value you use during the lease term and not the full purchase price. Leasing is a great option if you like to drive a new truck every few years, want the lowest possible monthly payment, or prefer to stay within warranty coverage at all times. Financing, on the other hand, lets you build equity and own the truck outright, a better fit for high-mileage drivers or anyone who wants to keep their truck long term. Not sure which is right for you? Our finance team at your Tri-Cities, WA GMC dealer is happy to run both scenarios side by side so you can see exactly what each option looks like for your budget.
