The curb weight of the 2007 Chevrolet Silverado 3500 HD II (GMT900) Crew Cab Long Box ranges from 2861 kg to 3337 kg (6305 to 7358 lbs) depending on configuration and trim level. This curb weight includes the vehicle’s standard equipment and fluids without passengers or cargo. The truck’s maximum gross vehicle weight rating (GVWR) spans from 4445 kg to 5171 kg (9800 to 11,408 lbs), indicating the total allowable weight including passengers, cargo, and the truck itself. This high maximum weight is characteristic of heavy-duty pickups, making the Silverado 3500 HD suitable for demanding towing and hauling tasks.

The ride height or ground clearance of the 2007 Chevrolet Silverado 3500 HD II Crew Cab Long Box is approximately 233 mm (9.17 inches). This ground clearance is vital for off-road capability and navigating uneven terrain, allowing the truck to clear obstacles with less risk of undercarriage damage.

A standard garage size for many homes is roughly 2440 mm (8 feet) wide and about 2130 mm (7 feet) high. The 2007 Chevrolet Silverado 3500 HD II Crew Cab Long Box, with its width of 2436 mm (95.9 inches) when mirrors are open, fits just within the width dimensions, but requires careful handling, especially with the mirrors extended. The height of up to 1934 mm (76.1 inches) allows clearance beneath typical garage door heights. However, its overall length of 6572 mm (258.7 inches) means many standard single-car garages might be too short for this vehicle, especially if space is needed for other items or for opening doors fully. Many owners of this slightly longer heavy-duty truck use larger or customized garage spaces.

Width and height figures were also slightly increased to improve interior comfort and road presence, with a width at mirrors open of 2436 mm (95.9 inches) and height around 1931-1934 mm (76 inches). These size upgrades translated into enhanced capability, better passenger space, and more robust vehicle architecture, aligning with evolving market demands for stronger, larger trucks capable of heavier hauling and towing.

These tire and rim options reflect the truck’s flexible design to accommodate both highway use and demanding off-road or worksite conditions.
