2017 GMC Sierra HD All Terrain X Packs 910lb-ft of torque, Looks Awesome

The GMC brand has previously offered their limited edition All Terrain X package for the Canyon and Sierra 1500, but for the 2017 model year, this sporty off-road package comes to the Sierra 2500HD. While the unique features of this package are predominantly aesthetic, the sum of the parts is a heavy duty pickup that offers more off-road capability than any Sierra HD before it.

“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 6.6L, this truck more than matches its bold good looks with true professional-grade capability.”

Sierra HD All Terrain X
The new 2017 GMC Sierra All Terrain X begins as a 2500HD crew cab with four wheel drive and the buyer’s choice of the 6.0L gasoline engine or the 6.6L Duramax diesel. To enhance the off-roading ability, the All-Terrain X package adds 18 inch black painted aluminum wheels wrapped in LT275/65R18 Goodyear Duratrac MT-rated tires, an underbody shield, an Eaton locking rear differential and the Z71 off-road suspension package.

Next, the All-Terrain X package has a big impact on the exterior appearance of the Sierra 2500HD, adding a unique body-color grille surround with All Terrain insert, body-color door handles, black power-adjustable heated and power-folding trailering mirrors, black belt moldings, front bumper skid plate and B-pillars, 4 inch black sport side steps, a spray-on bedliner and a black sport bar mounted in the bed with the All-Terrain logo stamped into the sides in red.

The 2017 GMC Sierra 2500HD All-Terrain X is offered in Summit White, but the truck just looks so great in Black Onyx, that everyone should order this truck in its fully blacked-out form.

I haven’t had a chance to see the 2500HD All-Terrain X in person, but I have recently tested the Sierra 1500 All-Terrain X and in my opinion, this is the best looking package for any of the General Motors pickups. The blacked-out look is sinister and while this isn’t an extreme off-road package – it is more capable than the vast majority of ¾ ton trucks sold in America.

The biggest advantage that the 2017 GMC Sierra 2500HD All-Terrain X is that it comes standard with the 6.0L gasoline V8, it is also offered with the new 6.6L Duramax diesel engine, which delivers 445 horsepower and 910lb-ft of torque- making it the most powerful off-road package in America by a significant margin. Really, the only true competitor in the ¾ ton segment is the Ram 2500 Power Wagon and while the Ram has the advantage in suspension technology, the Power Wagon is “only” offered with the 6.4L Hemi. The Hemi packs 410 horsepower and 429lb-ft of torque, more than what you get with the Sierra gas engine, but far less than the output of the All-Terrain X Duramax diesel.

That heavy diesel engine will limit off-roading capabilities a bit, but it makes the 2017 GMC Sierra 2500HD All-Terrain X the most capable off-road truck in America. With the diesel engine, this off-road ready Sierra HD could serve as the ultimate work truck for those folks who have to deal with rough footing on the worksite.
