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

The Sierra 3500HD V Double Cab Long Bed has a curb weight ranging from 3083 kg to 3699 kg (approximately 6800 to 8150 lbs). This wide range depends on specific configurations like drivetrain, cab, bed options, and trim packages. A heavier vehicle like this generally offers greater stability and towing capacity, which is critical for heavy-duty tasks such as hauling trailers or transporting construction materials. The solid weight contributes to a commanding road presence but may impact fuel efficiency and maneuverability slightly in urban settings due to the mass. Owners should balance their needs between payload capacity and fuel consumption when choosing specific options.

The 2024 GMC Sierra 3500HD V Double Cab Long Bed offers a ride height or ground clearance between 257 mm and 284 mm (approximately 10.1 to 11.2 inches). This elevated stance is advantageous for off-road driving, allowing the truck to navigate uneven terrain, water crossings, and obstacles while reducing the risk of undercarriage damage. Higher ground clearance also improves approach and departure angles, essential for off-road trails and rugged conditions. For professional use and outdoor enthusiasts, this clearance ensures the truck can handle challenging environments typical for heavy-duty pickups.

Fitting the 2024 GMC Sierra 3500HD V Double Cab Long Bed inside a standard residential garage may be challenging due to its large dimensions. With a length of 6534 mm (257.0 inches or roughly 21.4 feet) and a height up to 2054 mm (80.9 inches or 6.74 feet), many standard garages designed for typical sedans or smaller SUVs may not accommodate this vehicle comfortably. Garage width is another constraint, as the truck's width with mirrors extended can reach 2457 mm (96.7 inches or about 8 feet). Homeowners considering this truck should measure their garage dimensions carefully and may need to fold side mirrors or opt for specialized garages or carports when parking this heavy-duty pickup.

The width of the 2024 GMC Sierra 3500HD V Double Cab Long Bed ranges from 2079 mm (81.8 inches) with mirrors folded to 2457 mm (96.7 inches) with mirrors extended. This width is competitive within the heavy-duty pickup segment, offering a commanding road presence that's typical for trucks designed for heavy hauling. In comparison, similar heavy-duty pickups like the Ford F-350 or Ram 3500 have comparable widths but might vary slightly in mirror or overall body width. The broad width accommodates larger tires and a wide stance for stability during towing or off-road conditions but requires drivers to be mindful when maneuvering in tight spaces or narrow lanes.

The 2024 GMC Sierra 3500HD V Double Cab Long Bed offers several tire sizes, including 275/70 R18, 275/65 R20, 235/80 R17, and 235/80 R18. Each tire size corresponds to different rim sizes ranging from 17 to 20 inches in diameter. Larger rims with low-profile tires, like the 275/65 R20, generally provide improved handling and a smoother highway ride, while narrower and taller tires, such as 235/80 R17, offer better off-road traction and durability over rough terrain. The choice of tires impacts ride quality, fuel efficiency, load capacity, and suitability for different driving environments, making it essential to match tire specifications to the owner's driving preferences and purposes.

The Double Cab Long Bed configuration of the 2024 GMC Sierra 3500HD V features a longer cargo bed compared to regular and crew cab options. With this body style, the total vehicle length reaches 6534 mm (257.0 inches), making it ideal for users needing enhanced cargo capacity for larger items, construction materials, or landscaping equipment. The Long Bed allows for increased payload volume and length, which is especially important for commercial or heavy-duty uses. Although this adds to the overall length and may slightly affect maneuverability in tight spaces, it undeniably boosts the Sierra 3500HD's versatility and capability as a workhorse pickup truck.

Compared to its predecessor, the 2024 GMC Sierra 3500HD V Double Cab Long Bed (GMTT1XX facelift) builds upon the previous generation's robust platform with modern dimensions that slightly increase length and width for better ergonomics and cargo capacity. While maintaining the heavy-duty essence, the facelift introduced refined exterior styling, improved aerodynamics, and upgraded materials to enhance both appearance and functionality. Dimensionally, it remains similar but features subtle tweaks in width (with wider mirror options) and height to optimize ride comfort and off-road capability. Advanced technology and updated safety features also distinguish the 2024 model from its predecessor, reflecting the latest industry standards.

When compared to competitors like the Ford F-350 Super Duty and Ram 3500, the 2024 GMC Sierra 3500HD V Double Cab Long Bed holds its own as a large and capable heavy-duty pickup. Its length of 6534 mm (257.0 inches) is on par or slightly longer than many competitor long bed versions, providing comparable or greater cargo space. Width with mirrors folded (2079 mm or 81.8 inches) and extended (2457 mm or 96.7 inches) aligns with typical widths in this class, ensuring competitive stance and road presence. Height variations are also similar, contributing to off-road and towing capabilities. Overall, the Sierra 3500HD matches or slightly exceeds general dimensional expectations for this segment, making it a strong contender for professionals seeking maximum utility and durability.

The 2024 GMC Sierra 3500HD V Double Cab Long Bed boasts an impressive maximum weight capacity or Gross Vehicle Weight Rating (GVWR) that ranges between 5125 kg and 6350 kg (approximately 11,300 to 14,000 lbs), depending on the configuration and equipment levels. This high GVWR makes the truck suitable for heavy-duty applications such as towing large trailers, carrying heavy payloads, and demanding commercial tasks. The GVWR figure reflects the maximum combined weight of the truck, passengers, cargo, and optional equipment, underscoring the Sierra 3500HD's role as a truck built for tough work environments and heavy lifting while complying with safety and engineering standards.
