2011 Chevrolet Silverado 3500 HD II (GMT900, facelift 2011) Regular Cab Long Box Dimensions, Size & Specs

The curb weight of the 2011 Silverado 3500 HD II Regular Cab Long Box ranges from 2619 kg to 3277 kg (approximately 5774 to 7222 lbs). This heavy curb weight contributes to its ability to handle large payloads and towing demands efficiently, providing stability and durability on the road, especially for commercial or heavy-duty use.

The maximum weight rating of this model ranges between 4717 kg to 6078 kg (10,397 to 13,395 lbs), depending on the configuration. This impressive weight capacity underlines the Silverado 3500 HD II’s suitability for demanding towing and hauling tasks, making it a reliable choice for both professional and personal heavy-duty applications.

The vehicle offers a ride height or ground clearance between 218 mm and 224 mm (8.58 to 8.82 inches). This elevated clearance is vital for navigating rough terrains and off-road conditions, reducing the risk of undercarriage damage and enabling the truck to perform well in diverse environments.

With rear seats folded, this truck offers a luggage capacity of approximately 2138 liters (around 75.48 cubic feet). This generous cargo space is ideal for transporting tools, equipment, or large loads, further establishing the Silverado 3500 HD II as a versatile and practical pickup truck for heavy-duty work.

Given its length of 5715 mm (224.96 inches) and width of 2436 mm (95.91 inches) with mirrors opened, the Silverado 3500 HD II is quite large. Most standard residential garages (typically around 6 meters/20 feet in length and 3 meters/10 feet in width) might be tight, especially considering mirror width. Owners often need to fold mirrors or have extra-large garages to comfortably fit this truck.

Compared to the previous GMT900 generation, the 2011 Silverado 3500 HD II received a facelift with some refinements in exterior styling and technology but retained similar robust dimensions reflecting its heavy-duty nature. Typically, the facelift improved aerodynamics and interior comfort without major changes to size, maintaining the truck’s traditional full-sized heavy-duty footprint that emphasizes strong towing and payload capacities.

When compared to competitors like the Ford F-350 Super Duty or Ram 3500 from the same era, the Silverado 3500 HD II is competitively sized with similar length and weight parameters. All three models focus on maximum towing, payload, and durability, but the Silverado often slightly edges out in cargo bed volume and interior bulk. Dimension-wise, it is slightly wider due to extended mirrors, emphasizing utility over garage fit ease.

The truck comes equipped with rim sizes ranging from 6.5J x 17, 8J x 17, and 8J x 18, paired with tires sized 235/80 R17 or 265/70 R18. These relatively large, heavy-duty tires provide excellent load-bearing capacity and durability for heavy towing and hauling, while also contributing to a stable and robust ride on various road surfaces, though potentially a stiffer ride compared to smaller tires.

The 2011 Chevrolet Silverado 3500 HD II Regular Cab Long Box is a heavy-duty pickup built for the toughest jobs, favored for its trailering capacity and rugged construction. It is mainly used in commercial, agricultural, and industrial settings where maximum payload and towing abilities are critical. Additionally, it offers driver comfort improvements introduced in the facelift, including better materials and available tech upgrades, balancing work utility with everyday usability.
