The 2015 GMC Sierra All Terrain HD is a package available for the 2500HD and 3500HD double cab and crew cab models. This package takes the GMC Sierra in a more off-road-biased direction. Starting with the Z71 Off Road Package, the GMC Sierra All Terrain HD adds Rancho twin-tube shocks, skid plate and hill descent control.
The GMC Sierra All Terrain HD also comes with either 18 or 20-inch wheels.
“The new 2015 GMC Sierra HD lineup helps customers tackle tough jobs more comfortably, and with the new All Terrain HD, they can do it with greater style,” said Duncan Aldred, vice president of GMC Sales and Marketing. “Equally comfortable whether it’s a night on the town or traversing a remote job site, it has all the capability that customers demand from a GMC heavy-duty truck on the job.”
“3500HD models also include adjustable outside camper mirrors with a chrome cap. Additional exterior content includes light-emitting diode signature headlamps, body-color bumpers (chrome bumpers available), chrome mirrors covers and body side moldings and chrome front-lower bumper plate. Inside, a carbon fiber-inspired theme distinguishes the All Terrain from other models and includes the ALL TERRAIN logo on the instrument cluster. A rearview camera system also is standard.”
There are a host of interior upgrades including a built-in Wi-Fi hotspot, IntelliLink, OnStar with 4G LTE and Siri Eyes (free for iOS 6 and 7).
Here are some other goodies available for the GMC Sierra All Terrain HD:
- CornerStep rear bumper, EZ Lift and Lower tailgate, standard locking tailgate, standard upper tie-downs and other features that make cargo handling easier
- Standard StabiliTrak with Trailer Sway Control on all models
- Integrated cruise control, auto grade braking and diesel exhaust braking, for greater driving control and reduced brake wear on grades
