2024 GMC Sierra 2500HD V (GMTT1XX, facelift 2024) Double Cab Long Bed Dimensions, Size & Specs

This GMC Sierra 2500HD V Double Cab Long Bed features a ride height and ground clearance of 257 mm (10.1 inches). This elevated ground clearance enhances the vehicle's ability to traverse rough terrains, obstacles, and uneven surfaces without the underbody being damaged. On-road, this height improves driver visibility and contributes to the truck’s off-road capability, but it also means a higher center of gravity, which can influence handling dynamics. Overall, the 257 mm clearance strikes a functional balance suitable for both worksite conditions and highway driving.

The 2024 GMC Sierra 2500HD V Double Cab Long Bed has a curb weight ranging from 3018 kg to 3468 kg (6653 to 7647 pounds), depending on the specific configuration and equipment. The maximum weight capacity, which includes the vehicle’s gross combined weight rating (GCWR), spans from 4627 kg to 5080 kg (10,200 to 11,200 pounds). This significant payload and towing potential make the Sierra 2500HD V an ideal choice for demanding tasks, capable of hauling heavy loads and trailers, emphasizing its role as a robust heavy-duty pickup.

The 2024 GMC Sierra 2500HD V offers a versatile range of rim sizes to suit different driving needs and aesthetics. These include 7.5J, 17-inch, 18-inch, 8.5J, and 20-inch options. Correspondingly, tire sizes include 245/75 R17, 265/70 R17, 275/70 R18, 275/65 R20, 235/80 R17, 265/70 R18, and 265/60 R20. This variety allows owners to prioritize ride comfort, off-road capability, or on-road performance, depending on whether they prefer smaller rims with higher-profile tires or larger rims with lower-profile tires for a sportier appearance and handling.

Given its sizable dimensions—6534 mm (257.1 inches) in length, 2079 mm (81.8 inches) width with mirrors extended, and a height of 2027 mm (79.8 inches)—the 2024 GMC Sierra 2500HD V Double Cab Long Bed is generally too large for most standard residential garages. Standard single-car garages typically range around 6 meters (20 feet) in depth and about 3 to 3.6 meters (10 to 12 feet) in width. Therefore, unless the garage is custom-built or larger than average, comfortably parking this truck indoors will be challenging. Owners should plan for outdoor parking or large garage spaces.

The 2024 GMC Sierra 2500HD V represents the latest evolution in GMC’s heavy-duty pickup lineage. Compared to the fourth-generation Sierra 2500HD, the GMTT1XX chassis facelift version maintains a similar footprint but features refined dimensions to maximize interior space and utility. Length remains substantial for heavy-duty capability, and despite subtle design changes, the height and width stay within typical ranges for the class, ensuring compatibility with existing infrastructure. The newer generation typically incorporates modern engineering that optimizes weight distribution and payload capacity, often resulting in slight curb weight adjustments but improved overall performance and driver comfort.

In comparison to similar heavy-duty pickups like the Ford F-250 Super Duty and Ram 2500, the 2024 GMC Sierra 2500HD V Double Cab Long Bed is very competitive. Dimensionally, it is similar in length and height to the Ford F-250 and slightly larger or comparable to the Ram 2500, especially when considering bed length and cab configuration. The Sierra offers a blend of rugged capability with upscale features typically associated with GMC's premium branding, including advanced technology, comfort, and multiple powertrain options. Its range of rim and tire options also provides versatility to match various work or leisure requirements, giving it an edge in customization over some rivals.

While the exterior dimensions of the 2024 GMC Sierra 2500HD V Double Cab Long Bed highlight its length and cargo capability, the interior is designed to balance passenger comfort and utility. The Double Cab configuration offers additional rear seating space compared to the regular cab, though it is less spacious than the Crew Cab variant. This setup suits users who need extra passenger room but prioritize cargo bed length for hauling. High-quality materials, ergonomic design, and advanced infotainment features contribute to a comfortable driving environment. Despite the truck’s robust size, the cabin remains practical for both work and daily driving.

With a curb weight ranging from 3018 kg to 3468 kg (6653 to 7647 lbs) and a maximum gross vehicle weight rating between 4627 kg and 5080 kg (10,200 to 11,200 lbs), the 2024 GMC Sierra 2500HD V Double Cab Long Bed is engineered for high performance in towing and payload tasks. These numbers enable it to tow heavy trailers and haul substantial loads, making it ideal for commercial use, heavy-duty hauling, and recreational towing. Exact towing capacity varies based on engine choice and configuration, but the heavy-duty architecture inherently supports substantial weight, ensuring durability under rigorous conditions.

The width of the 2024 GMC Sierra 2500HD V Double Cab Long Bed is 2079 mm (81.8 inches) when the side mirrors are opened, which is the full operational width while driving or parking. Without mirrors extended, the truck is narrower, improving maneuverability in tighter spaces. However, when mirrors are folded in, visibility decreases, so drivers often need the mirrors open for safety, especially when towing or reversing. The wide stance with mirrors is typical for trucks in this segment, helping stability but requiring care in narrow lanes, parking garages, or construction sites.
