2011 Chevrolet Silverado 2500 HD II (GMT900, facelift 2011) Extended Cab Long Box Dimensions, Size & Specs

With mirrors opened, the Silverado 2500 HD II measures 2032 mm (79.9 inches) wide. This width is wider than many regular vehicles, which means caution is needed when parking or maneuvering through narrow streets or tight parking spots. The wide side mirrors are necessary for improved visibility, especially when towing trailers, but they do extend the vehicle’s footprint. Drivers often need to fold in mirrors in cramped situations and plan parking spots accordingly. Maneuverability in urban or crowded areas can be challenging because of this, although the vehicle’s turning radius is typical for its size and class.

The curb weight of the Silverado 2500 HD II Extended Cab Long Box ranges from 2786 kg to 3300 kg (6144 to 7277 lbs), depending on the specific configuration and options. This substantial weight reflects its heavy-duty capabilities, robust construction, and equipped features. Heavier weight translates to a stable ride, greater towing, and payload capacities, but it also means the truck may use more fuel and have different handling dynamics compared to lighter vehicles. Drivers benefit from a solid and confident driving experience, especially during hauling, but should be mindful of stopping distances and vehicle inertia.

When the rear seats are folded, the 2011-2014 Chevrolet Silverado 2500 HD II Extended Cab Long Box offers a luggage capacity of 2138 liters (approximately 75.5 cubic feet) inside the cabin area. This volume is quite generous for a pickup truck, allowing for substantial storage beneath the extended cab area, making it useful for securing tools, equipment, or other cargo inside the vehicle in addition to the traditional truck bed. This versatility makes it highly functional for both work and recreational purposes.

The Silverado 2500 HD II has a ground clearance of between 214 mm and 216 mm (8.4 to 8.5 inches), which is typical for heavy-duty pickup trucks designed for rugged use. This clearance enables the truck to navigate uneven terrain, obstacles, and off-road conditions without damaging the undercarriage. It provides sufficient height for water fording and rough path traversal, contributing to its status as a versatile and capable workhorse in challenging environments. It also improves visibility and road presence on regular roads.

Due to its large size, the Silverado 2500 HD II Extended Cab Long Box measures 6337 mm (249.4 inches) in length and nearly 2 meters wide including mirrors, which makes fitting into a standard residential garage challenging. Typical garages measure about 6 meters (20 feet) in length and 2.4 meters (8 feet) in width. While the truck may fit in length-wise if the garage is oversized, the width including mirrors likely exceeds garage width dimensions, requiring careful mirror folding and tight clearance. Owners of this model generally require larger or custom garages or prefer parking outdoors for daily accessibility.

The Silverado 2500 HD II generation (2011–2014) brought some updates and styling improvements over the GMT900 predecessor (2007–2010). Dimensionally, the facelifted GMT900 tended to keep similar length and width but introduced slight refinements to height and ground clearance to improve ride comfort and off-road performance. For example, the extended cab long box maintained a similar length near 6337 mm (around 20.8 feet) but benefitted from optimized bed and cab configurations. The design focused more on aerodynamic styling and better interior space utilization compared to the previous generation, improving usability while maintaining ruggedness.

The Silverado 2500 HD II Extended Cab Long Box is competitive in size compared to other heavy-duty pickups such as the Ford F-250 Super Duty and RAM 2500. Its length of 6337 mm (249.4 inches) is roughly on par, though some competitors may have slightly different bed or cab configurations affecting overall length. Width with mirrors is wide but typical for trucks intended for towing and hauling. Ground clearance and curb weight fall within the expected range for heavy-duty trucks, balancing capability and drivability. The Silverado offers a balanced combination of interior space, cargo area, and external dimensions appealing to both work and lifestyle buyers.

The 2011-2014 Silverado 2500 HD II uses various rim sizes ranging from 17 to 20 inches including 7.5J x 17, 8J x 18, 8.5J x 18, and 8.5J x 20. Tire options include sizes like 245/75 R17, 265/70 R17, 265/70 R18, and 265/60 R20. Larger rims, such as 20 inches, typically offer improved road grip and handling on pavement but might sacrifice some ride comfort. Smaller rims with higher profile tires provide better cushioning on rough terrain, beneficial for off-road and heavy-duty use. These sizing options allow customization based on driver preferences, whether for towing, off-road, or daily driving comfort.

The Chevrolet Silverado 2500 HD II Extended Cab Long Box was designed as a tough, reliable heavy-duty pickup truck for professional and personal use. Produced from 2011 through 2014, it featured powerful V8 engines, durable chassis, and a spacious extended cab suitable for crew and cargo. It excelled in towing and payload capacity, making it popular among contractors, farmers, and enthusiasts needing robust performance. The truck combined utility with comfort, offering modern amenities and improved interiors thanks to its facelift. Its balance of size, power, and functionality solidified its place in the heavy-duty pickup market.
