2014 GMC Sierra 1500 IV (GMTK2XX) Regular Cab Long Box Dimensions, Size & Specs

The curb weight of the 2014 GMC Sierra 1500 IV Regular Cab Long Box ranges between 2071 kg and 2232 kg (approximately 4565 to 4920 pounds), which reflects the vehicle's weight without passengers or cargo. The maximum weight capacity, or Gross Vehicle Weight Rating (GVWR), ranges from 3039 kg to 3175 kg (about 6700 to 7000 pounds). This capacity indicates the truck's ability to carry heavy loads and tow significant trailers, highlighting its capability as a work truck. The weight range can vary depending on specific configurations and trim options.

The GMC Sierra 1500 IV Regular Cab Long Box provides a ride height or ground clearance between 212 mm and 223 mm (8.3 to 8.8 inches). This ground clearance level is favorable for moderate off-road driving, allowing the vehicle to clear obstacles such as rocks, ruts, and uneven terrain without damage to the undercarriage. It also contributes to better handling on rough surfaces. While not designed as a hardcore off-roader, this clearance combined with its robust build gives the Sierra 1500 strong utility both on and off paved roads.

The standard rim size for this model is 8J x 17 inches, meaning an 8-inch width rim with a 17-inch diameter. Tire sizes available are 245/70 R17 and 265/70 R17, where the first number indicates tire width in millimeters, the second is the tire's sidewall height as a percentage of the width, and 'R17' denotes the 17-inch rim diameter. These sizes deliver a good balance between ride comfort, handling, and load capacity suitable for the Sierra 1500's work and daily driving roles.

The 2014 GMC Sierra 1500 IV Regular Cab Long Box features an impressive luggage or cargo capacity of approximately 2162 liters (76.4 cubic feet). This large volume highlights the utility nature of this pickup, especially with its long bed configuration, providing ample space for transporting bulky loads, tools, equipment, or recreational gear. The spacious cargo box makes it versatile for both professional use in hauling heavy materials and personal use for outdoor activities.

Fitting the 2014 GMC Sierra 1500 IV Regular Cab Long Box into a standard residential garage can be challenging given its length of 5701 mm (224.4 inches) and width of 2032 mm (79.9 inches) with mirrors extended. Most typical single-car garage dimensions measure approximately 6 meters (20 feet) deep and 3 meters (10 feet) wide internally, which might accommodate the truck lengthwise but leave little clearance space. Additionally, the width with mirrors may require folding the mirrors to avoid contact with garage walls. Owners with standard garages may find parking tight and should measure their garage space carefully before ownership.

Compared to its predecessor, the 2014 GMC Sierra 1500 IV Regular Cab Long Box shows a modest increase in size and refinement. The previous generation was typically slightly shorter and narrower, with incremental changes in height depending on model options. The 5701 mm length for this generation represents a move towards maximizing cargo bed length and interior space in the cab, improving utility. Additionally, weight has generally increased due to enhanced safety features and optional equipment packages. This evolution provides better capability and comfort while retaining the rugged nature expected from the Sierra 1500 series.

In comparison to similar full-size pickups from 2014, such as the Ford F-150 Regular Cab Long Bed or the Ram 1500 Regular Cab Long Bed, the GMC Sierra 1500 IV is competitive in size, power, and capability. With a length around 5701 mm (224.4 inches), it is slightly longer than some rivals emphasizing maximum bed space. Its width of 2032 mm (79.9 inches) with mirrors extended is comparable, although some competitors may offer more narrow profiles for urban maneuverability. The Sierra’s ground clearance, weight range, and payload capacity align well with class standards, making it a strong contender for buyers looking for a balanced mix of comfort, performance, and hauling efficiency.

The 2014 GMC Sierra 1500 IV Regular Cab Long Box combines a traditional rugged pickup design with practical utility features such as a spacious long bed for large cargo loads. It offers durable materials, strong structural integrity, and wide tires that enhance stability and traction. The regular cab configuration prioritizes bed space and payload over passenger volume, ideal for commercial users or those needing to transport bulky items. Features often include advanced towing aids, trailer sway control, and comfortable driver ergonomics, emphasizing functionality and reliability for demanding work environments.

Although fuel efficiency greatly depends on the engine and drivetrain selections, the 2014 GMC Sierra 1500 IV Regular Cab Long Box typically offers a range of V6 and V8 engine options designed for power and towing. Base engines might achieve fuel economy figures in the range of approximately 12-14 L/100 km (17-20 mpg) combined, while more powerful V8 variants yield slightly lower efficiency due to increased fuel consumption. Engine options focus primarily on delivering torque and power for towing and hauling rather than fuel economy, consistent with the truck’s role as a heavy-duty work vehicle.
