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

The curb weight of the 2024 GMC Sierra 3500HD V Regular Cab Long Bed ranges from 2870 kg (6329 lbs) to 3475 kg (7659 lbs) depending on equipment and optional features. Its maximum gross vehicle weight rating (GVWR) varies between 4966 kg (10945 lbs) and 6350 kg (14000 lbs), enabling it to accommodate heavy payloads and towing needs. This significant weight capacity reflects its design focus on durability and utility, making it well-suited for commercial, agricultural, or construction use where large loads are common.

The 2024 GMC Sierra 3500HD V Regular Cab Long Bed offers a ride height or ground clearance of 266 mm (10.5 inches) to 285 mm (11.2 inches), depending on suspension tuning and tire options. This generous ground clearance enhances its off-road ability, allowing the truck to navigate rough terrain, uneven surfaces, and obstacles more effectively. For work environments that demand traversing dirt roads, construction sites, or rugged trails, this clearance is advantageous for preventing underbody damage and improving overall mobility and approach/departure angles.

Given its length of 6002 mm (236.3 inches) and width with mirrors open up to 2457 mm (96.7 inches), the 2024 GMC Sierra 3500HD V Regular Cab Long Bed is generally too large to comfortably fit into a standard residential garage. Typical garage door widths range from about 2440 mm (96 inches) for a single-car garage, meaning this truck may require mirrors to be folded or custom accommodations for clearance. Its height of up to 2056 mm (80.9 inches) should fit within most garage door heights, but the overall length and width, especially with mirrors extended, make indoor parking challenging without ample space.

Compared to the previous generation GMC Sierra 3500HD, the 2024 V (GMTT1XX, facelift 2024) Regular Cab Long Bed has maintained a very similar overall size profile but includes slight refinements. The length remains close to around 6000 mm (236 inches), preserving the long bed utility. The width, especially with mirrors, remains wide to support towing and visibility improvements, though exact previous generation mirror width was slightly less extensive. Height also remains consistent within the 2038 mm to 2056 mm (80 to 81 inches) range, ensuring cabin comfort and ground clearance are sustained or slightly improved to meet modern demands.

When compared to other heavy-duty pickups like the Ford F-350 Super Duty or the Ram 3500, the 2024 GMC Sierra 3500HD V Regular Cab Long Bed stands competitively in size. Its length of 6002 mm (236.3 inches) is on par with or slightly longer than many competitors, primarily due to the long bed configuration. Width with mirrors extended up to 2457 mm (96.7 inches) is comparable, supporting wide load trails and towing mirrors. Height also falls within a standard range for pickups of this class (around 2038-2056 mm). These size dimensions make the Sierra 3500HD a formidable contender, balancing work capability with maneuverability that is expected in its segment.

The 2024 GMC Sierra 3500HD V Regular Cab Long Bed supports multiple rim sizes, including 7.5J x 17, 8J x 18, 8.5J x 18.5, 8.5J x 20, and 6.5J x 17 inches, providing options that balance aesthetics, strength, and ride quality. Tire sizes include 245/75 R17, 265/70 R17, 275/70 R18, 275/65 R20, 235/80 R17, and 235/80 R18, allowing customization for different terrains and demands. Larger rims with wider, lower-profile tires generally improve on-road handling and stability, while smaller rims with taller tires enhance off-road performance and ride comfort by better absorbing road irregularities.

The curb weight of the 2024 GMC Sierra 3500HD V Regular Cab Long Bed ranges widely from 2870 kg (6329 lbs) to 3475 kg (7659 lbs) depending on configuration and options. Heavier weight generally means more robust build quality and towing capacity but can negatively impact fuel efficiency as the engine must work harder to move the extra mass. Additionally, higher weight contributes to greater momentum, affecting braking distance and handling agility, especially in tight maneuvers. However, this heavy-duty weight is a necessary trade-off for durability, payload, and off-road capability in demanding conditions.

The height of the 2024 GMC Sierra 3500HD V varies between 2038 mm (80.2 inches) and 2056 mm (80.9 inches), while the width with mirrors can range from 2076 mm (81.7 inches) folded to 2457 mm (96.7 inches) opened. These variations are caused by factors such as suspension setups, tire choices, and mirror adjustment. Certain trims may feature a raised suspension or off-road package increasing height, while tire size influences overall vehicle footprint. Mirrors designed to fold or extend for visibility during towing explain the wide width range. These adjustable dimensions enhance versatility in different driving and parking scenarios.

The long bed configuration established in the 2024 GMC Sierra 3500HD V Regular Cab offers expanded cargo capacity essential for heavy-duty users needing to haul large, bulky, or long items. The longer cargo area improves utility for construction materials, landscaping tools, or equipment transport compared to standard or short bed versions. This configuration complements the truck's robust maximum weight ratings (up to 6350 kg or 14000 lbs), supporting larger payloads without compromising vehicle balance or performance. For commercial and industrial users, the long bed increases efficiency by reducing the need for trailers or frequent trips.
