The Sierra HD Joins its Siblings With the All Terrain X Treatment

2017 GMC Sierra 2500HD All Terrain X

Earlier, GMC revealed some of its most off-road-ready pickups in the All Terrain X versions of the Canyon and Sierra 1500. Now, the big brother of those pickups, the Sierra HD, gets the same off-road package.

This package is only available on the Sierra 2500HD crew cab with four-wheel drive, so it starts out with that big, imposing body. Under its hood, buyers can opt for either the 6.0-liter V-8 with 360 horsepower and 380 pound-feet of torque or the 6.6-liter Duramax V-8 diesel with 445 horsepower and 910 pound-feet of torque.

Included in this package are features similar to the All Terrain X versions of its smaller siblings. These include 18-inch black-painted wheels wrapped in LT275/65R18 Goodyear Duratrac MT tires, a body-color grille surround with All Terrain insert, body-color door handles and bodyside moldings, black-painted power trailering mirrors, black belt moldings, front bumper skid plate and B-pillars, 4-inch step assists, and a black sport bar mounted in the bed.

While those features are great, what really makes this model truly badass are its off-roading goodies, including the Z71 suspension package, an Eaton auto locking rear diff, and the underbody shields.

Rounding out the features on this truck are all-weather floor liners, a spray-on bedliner, front and rear park assist, a heated steering wheel, GMC Intellilink with an 8-inch touchscreen, a remote-locking tailgate, a remote starter, a rearview camera, adjustable pedals, leather seating with heat up front, and wireless charging.
