2015 GMC Sierra 1500 IV (GMTK2XX, facelift 2016) Crew Cab Short Box Dimensions, Size & Specs

With the mirrors opened, the 2015 GMC Sierra 1500 IV spans 2032 mm (80 inches) in width. This width is relatively broad due to the large side mirrors typical for pickup trucks, enhancing visibility but also requiring extra caution in narrow lanes or when passing through tight spaces. Drivers should be mindful of the vehicle's width especially in urban environments or on narrow country roads. While this width is standard for full-size pickups, it can make navigating confined areas more challenging.

The height of the 2015 GMC Sierra 1500 IV Crew Cab Short Box varies between 1879 mm and 1884 mm (74 to 74.2 inches) depending on specific trim and tire configurations. This height places the truck in the mid to tall range for pickups, which generally means it fits into many residential garages but might be tight in some older or lower-clearance garages. The slight variation in height is usually due to differences in suspension or tires. Drivers should measure garage openings to ensure safe clearance, especially if additional accessories like roof racks are added.

The 2015 GMC Sierra 1500 IV Crew Cab Short Box has a curb weight ranging from 2285 kg to 2486 kg (5038 to 5480 lbs), depending on equipment and trim. The maximum weight or gross vehicle weight rating (GVWR) ranges from 3130 kg to 3266 kg (6900 to 7200 lbs). These weights indicate a robust full-size pickup capable of substantial towing and payload. The relatively high GVWR means the Sierra can handle heavy loads, making it suitable for towing trailers, boats, or carrying construction materials. Weight plays a crucial role in vehicle stability and braking performance, so adhering to these limits ensures both safety and vehicle longevity.

With a luggage capacity of 1512 liters (approximately 53.4 cubic feet), the 2015 GMC Sierra 1500 IV Crew Cab Short Box offers generous cargo space in its bed area. This capacity allows owners to transport large and bulky items such as tools, equipment, or recreational gear comfortably. Compared to other full-size pickups in the same class, this capacity is competitive and meets the needs of most users seeking utility without sacrificing passenger comfort. The short box configuration strikes a balance between cargo volume and overall vehicle length.

The 2015 GMC Sierra 1500 IV offers a ride height or ground clearance between 222 mm and 226 mm (8.7 to 8.9 inches). This clearance is typical for a full-size pickup and provides a good balance between on-road comfort and off-road capability. The ground clearance allows the vehicle to handle rough terrain, obstacles, and uneven surfaces without damaging the undercarriage. It also contributes to better visibility for the driver. For everyday driving, this height is comfortable and does not usually pose challenges for entering or exiting standard garages.

The 2015 GMC Sierra 1500 IV Crew Cab Short Box, with its 5825 mm (229.3 inches) length, 2032 mm (80 inches) width including mirrors, and approximately 1880 mm (74 inches) height, generally fits into many standard residential garages. However, many garages have door widths ranging from 2400 mm to 2700 mm (94.5 to 106 inches), so the truck’s width with mirrors folded is more relevant. Drivers should ensure side mirrors are folded to reduce width and measure their garage clearance height and length, including space for opening doors and maneuverability. Tight spaces may require careful entry and exit.

Compared to its predecessor, the 2014 GMC Sierra 1500 III generation, the 2015 GMC Sierra 1500 IV (GMTK2XX) Crew Cab Short Box saw modest dimensional adjustments, maintaining similar length and width but gaining subtle improvements in aerodynamics and cargo bed design. The 2015 model improved on weight efficiency and slightly enhanced payload and towing capacities due to advancements in chassis strength and powertrain options. These incremental changes resulted in better overall usability and driving dynamics while preserving the familiar footprint, making it a modern yet familiar upgrade for Sierra enthusiasts.

The 2015 GMC Sierra 1500 IV Crew Cab Short Box's length of 5825 mm (229.3 inches) and width of 2032 mm (80 inches) with mirrors open positions it competitively within the full-size pickup segment. The Ford F-150 and Ram 1500 of similar years have comparable lengths and widths, generally within a few centimeters difference. Ride height and ground clearance are also similar across these models. However, styling, interior layout, and bed configurations differ. Sierra’s cargo capacity and weight ratings align well with its competitors, making it a strong contender on size and utility metrics.

The 2015 GMC Sierra 1500 IV Crew Cab Short Box is equipped with rim sizes of 8J x 17 inches, paired with tire options of 245/70 R17 or 265/70 R17. These tire dimensions balance ride comfort, traction, and durability suitable for both on-road and moderate off-road use. Larger tires provide better grip and ground clearance, enhancing the vehicle's capability in various conditions. The 17-inch rims are common for this truck size, offering a smooth ride without compromising load-bearing capacity or durability on rugged terrains.
