2024 GMC Sierra 3500HD V (GMTT1XX, facelift 2024) Crew Cab Long Bed Dimensions, Size & Specs

The height of the 2024 GMC Sierra 3500HD V Crew Cab Long Bed stands at 2049 mm (80.7 inches). This height facilitates generous cabin space and ground clearance, enabling superior off-road capability and visibility. However, it also means that clearance in low-ceiling environments like garages or car washes needs to be carefully considered. The tall profile contributes to the truck's commanding presence while supporting the payload and towing ratings expected from a heavy-duty pickup.

The curb weight of this GMC Sierra ranges from 3122 kg to 3740 kg (6884 lbs to 8249 lbs), depending on configuration and options. The truck can handle a maximum weight (Gross Vehicle Weight Rating - GVWR) from 5148 kg up to 6350 kg (11350 lbs to 14000 lbs). This large range in weight capability highlights the truck's heavy-duty nature, capable of handling immense payloads and towing heavy trailers, making it ideal for demanding commercial or recreational use.

This model features a ride height or ground clearance between 264 mm and 283 mm (10.4 inches to 11.1 inches). Such clearance is beneficial for driving over uneven, rough terrains without damaging the undercarriage. Additionally, this height enhances off-road capability and provides better water fording ability. Higher ground clearance is crucial for trucks tasked with off-road or construction site work, improving their overall versatility and performance.

The 2024 GMC Sierra 3500HD V Crew Cab Long Bed offers multiple tire and rim size combinations tailored for performance and load capacity. Rim sizes include 8J x 18, 8.5J x 20, and 6.5J x 17 inches. Corresponding tire sizes are 275/70 R18, 275/65 R20, 235/80 R17, and 235/80 R18. These options allow buyers to prioritize durability, ride comfort, or off-road capability depending on their needs, ensuring the truck can be outfitted for various driving conditions and heavy-duty tasks.

Fitting the GMC Sierra 3500HD V Crew Cab Long Bed into a standard residential garage can be challenging due to its considerable dimensions. With a length of 6776 mm (266.6 inches), a maximum width up to 2457 mm (96.7 inches) including mirrors, and a height of 2049 mm (80.7 inches), many average garages designed for passenger cars or smaller trucks might be too small. Owners typically need garages with at least 7 meters (23 feet) of length, 2.5 meters (8.2 feet) width clearance without mirrors, and ceilings higher than 2.1 meters (7 feet) to comfortably accommodate this truck.

While exact predecessor specs vary, the new generation’s overall length of 6776 mm (266.6 inches) and width up to 2457 mm (96.7 inches with mirrors) represent a slight size increase to enhance interior space and cargo capacity. Height remains similarly high around 2049 mm (80.7 inches), maintaining excellent ground clearance and rugged looks. The slight dimensional growth supports increased payload, towing performance, and occupant comfort, reflecting GMC’s evolution toward a more capable and versatile heavy-duty truck.

In terms of size, the 2024 GMC Sierra 3500HD V Crew Cab Long Bed stands tall among its heavy-duty pickup truck peers like the Ford F-350 and Ram 3500. Its length of 6776 mm (266.6 inches) and width range of 2079 to 2457 mm (81.8 to 96.7 inches) with mirrors are competitive, offering spacious cargo and cabin room. The ride height between 264 and 283 mm (10.4 to 11.1 inches) grants excellent off-road clearance, paralleling or surpassing some rivals. Overall, Sierra 3500HD V combines traditional heavy-duty dimensions with modern finishes, positioning itself as a strong contender in the 3/4-ton pickup truck segment.
