The 2007 GMC Sierra 1500 III (GMT900) Extended Cab Long Box measures an impressive length of 6325 mm (approximately 249 inches or 20.75 feet). When considering width, with mirrors opened, it spans about 2029 to 2031 mm (around 79.9 to 80 inches). These dimensions classify it as a large pickup truck, catering well to users needing considerable cargo space and on-road presence. The extended cab and long box configuration contribute to its overall size, maximizing both passenger accommodations and cargo bed length.
The height of this GMC Sierra is between 1868 to 1870 mm (approximately 73.5 to 73.6 inches). Ground clearance, which is crucial for off-road capability and navigating uneven terrain, ranges from 230 to 240 mm (about 9 to 9.45 inches). This combination of height and clearance strikes a balance, allowing the truck to offer good road visibility, easier access to the cabin, and reasonable off-road competency typical of a full-size pickup truck.
The curb weight—the weight of the vehicle without passengers or cargo—ranges from 2378 kg to 2499 kg (roughly 5247 to 5512 lbs). The maximum allowable gross vehicle weight, which includes the vehicle, passengers, cargo, and trailer tongue weight, ranges between 3130 kg and 3175 kg (around 6897 to 7000 lbs). These figures underline the truck’s capability to carry heavy payloads while maintaining stability and safety.
Given its generous length of 6325 mm (249 inches or about 20.75 feet), width of up to 2031 mm (80 inches), plus mirrors, the 2007 GMC Sierra 1500 III Extended Cab Long Box might present a tight fit in a standard residential garage. Most common single-car garages have a width of approximately 2.4 to 2.7 meters (approximately 8 to 9 feet) and a length of around 5.5 to 6 meters (18 to 20 feet). Therefore, the Sierra’s length likely exceeds typical garage lengths, making indoor parking challenging unless you have an oversized or specially designed garage space.
With the rear seats folded, the GMC Sierra 1500 III Extended Cab Long Box offers a rear luggage capacity of approximately 2138 liters (75.5 cubic feet). This significant volume allows for transportation of bulky or numerous items inside the cab area. Additionally, its long box bed adds considerable external cargo capacity, suitable for hauling equipment, construction materials, or recreational gear, making it a highly versatile pickup for both work and leisure purposes.
This model typically comes equipped with rims sized 7.5J x 17 inches, paired with tire options of either 245/70 R17 or 265/70 R17. These sizable tires and rims provide a blend of durability, traction, and ride comfort, optimized for the combination of urban, highway, and moderate off-road driving conditions. They help support the truck’s overall weight and load capacity while ensuring handling is stable.
Compared to its predecessor, the GMC Sierra 1500 II generation, the GMT900 (III generation) Extended Cab Long Box model increased slightly in overall dimensions, notably in length and width to provide better cabin and cargo space. Weight also rose due to added features, sturdier frames, and updated safety equipment, with curb weights in the range of 2378 to 2499 kg, reflecting the emphasis on improved capability and comfort. The increase in size supports greater payload and towing capacities, aligning with evolving market demands for full-size pickups.
When compared to competing vehicles like the Ford F-150, Chevrolet Silverado 1500, and Dodge Ram 1500 of the same era, the GMC Sierra 1500 III Extended Cab Long Box is similarly sized, with a length near 6325 mm (249 inches) and width around 2030 mm (80 inches with mirrors). These trucks all balance passenger comfort, ample cargo bed length, and substantial towing capacity. The Sierra's slightly longer length and wide stance place it at the upper end of standard full-size pickups, meaning it offers competitiveness in hauling capacity and interior space, while mirroring typical ground clearance and ride height expectations for this segment.
The ride height, also known as ground clearance, of the GMC Sierra 1500 III Extended Cab Long Box ranges from 230 to 240 mm (approximately 9 to 9.45 inches). This elevation is designed to allow drivers to negotiate various terrains without damage to the undercarriage, making it suitable for both highway driving and moderate off-road use. It strikes an optimal balance by providing a commanding view of the road and better obstacle clearance, while keeping the center of gravity low enough to maintain good stability and handling on paved roads.
