GMC’s Heavy Duty gets off-road chops

The GMC Sierra HD is getting some much-needed powertrain updates for the 2017 model year, but that’s not the only change happening. GMC’s All Terrain X package is now being added as an optional package for the 2500-series pickup. The Sierra HD All Terrain X joins the Sierra 1500 and Canyon All Terrain X to round out GMC’s line of off-road themed trucks.

“The new Sierra HD All Terrain X’s powerful attitude reflects a popular trend in very capable off-road trucks, executed with a range-topping level of refinement — a combination of attributes GMC has cultivated for years,” said Duncan Aldred, vice president of GMC Sales and Marketing. “And with the new, available Duramax 6.6-liter, this truck more than matches its bold good looks with true professional-grade capability.”

The All Terrain X basically takes the Z71 off-road package and throws on some cosmetic and parts changes designed to appeal to modern truck buyers who treat their trucks more like a blank canvas than as a work tool. The package does bring several functional updates to the Z71 package, meaning this isn’t just a mere appearance package.

Customers can order the All Terrain X package on the 2017 Sierra 2500 HD with either the 6.0-liter gasoline V-8 or the newly updated 6.6-liter Duramax V-8 turbodiesel. It is only offered in 4WD and in the crew cab configuration. Color choices are limited to Black Onyx and Summit White.

There’s plenty more details found on the 2017 Sierra 2500HD All Terrain X, so keep reading for more.

What makes the GMC Sierra 2500HD All Terrain X special

The All Terrain X package brings several cosmetic and functional updates to the Sierra HD. It stars with a monochromatic color scheme, with the bumpers, grille surround, and door handles all wearing a black finish. Minimal chrome is found, limited to the grille inserts, fog light surrounds, Duramax hood scoop, headlights, and all exterior badging. The wheel, side steps, tow hooks, and side mirrors all wear a blacked-out appearance.

The quickest identifier of the All Terrain X package is the bed-mounted sports bar surrounding the back window. It features mounting points for optional LED off-road lights and sail panels with sunken lettering spelling out “SIERRA” in red script. An incorporated center high-mounted stop light resides in the center of the main horizontal bar.

Functionality wise, the All Terrain X sports blacked-out 18-inch aluminum wheels wrapped in aggressive LT27/65-series Goodyear Duratrac MT tires. And since the All Terrain X package builds on the Z71 Off-Road package, the truck comes with upgraded Rancho shock absorbers, underbody skid plating, tow hooks, deleted front air dam, and the Eaton G80 Automatic Locking rear differential.

Furthermore, the All Terrain X package brings black, four-inch diameter side steps; a spay-on bedliner; front and rear park assist; a heated steering wheel, all-weather floor liners; trim-specific badging; and trailering side mirrors that are power-adjustable and power-folding with heated glass, integrated turn signals, and LED rear guidance lamps.

Speaking of trailering, the Sierra HD comes standard with a 2.5-inch receiver hitch. Its 6.0-liter V-8 offers up 360 horsepower and 380 pound-feet of torque. Most folks will opt for the heavily revised 6.6-liter Duramax V-8 with its class-leading 445 horsepower, along with its and 910 pound-feet of torque. The improvements to the 2017 Duramax include an all-new air induction system that helps keep temperatures down while shoving the turbo full of cool, clean air. A revised ECU tuning further pushes the turbodiesel to have 12 percent more power and 19 percent more torque than last year’s model.

While fifth-wheel towing isn’t likely going to happen thanks to the bed-mounted sports bar, the 2017 GMC Sierra 2500HD can tow 14,500 pounds from its frame-mounted receiver hitch.

Aside from the All Terrain X package, the 2017 Sierra HD has GMC’s eight-inch IntelliLink infotainment system, Wi-Fi hotspot, wireless phone charging, Teen Driver, a remote-locking tailgate, remote starting, Rear Vision Camera, adjustable pedals, and leather seats with heated front seats.
