1992 Chevrolet Suburban (GMT400) Dimensions, Size & Specs

The width of the 1992 Chevrolet Suburban (GMT400) ranges from 1940 mm to 1956 mm (76.4 to 77 inches). This generous width contributes to vehicle stability and interior roominess for passengers. However, the substantial width requires drivers to be more cautious when navigating narrow streets or tight parking spaces. Despite this, the width is fairly standard for full-size SUVs of the era and is manageable with careful driving.

The height of the 1992 Chevrolet Suburban (GMT400) varies between 1748 mm and 1910 mm (68.8 to 75.2 inches). This variation is influenced by factors such as different suspension setups, optional roof racks, or trim levels. The taller models offer improved ground clearance and headroom, enhancing off-road capability and passenger comfort. The height plays a role in overall aerodynamics and garage fit considerations.

The curb weight of the 1992 Chevrolet Suburban (GMT400) ranges from approximately 2102 kg to 2590 kg (4634 to 5709 lbs), depending on specific configuration, engine, and options selected. The maximum weight (gross vehicle weight rating) varies between 3250 kg and 3901 kg (7165 to 8599 lbs). A heavier curb weight adds to ride stability and durability but may affect acceleration and fuel efficiency. The high maximum weight rating signifies the SUV's capability to carry heavy loads or tow substantial trailers, making it suitable for work and family hauling needs.

The 1992 Chevrolet Suburban (GMT400) came equipped with several tire size options including 235/75 R15, 235/75 R15 H, 285/70 R16 T, 245/75 R16 T, 245/75 R16, 225/75 R16, and 245/75 R16 C. These sizes influence ride comfort, road grip, and handling characteristics. Larger tires with higher sidewalls improve off-road capability and absorb bumps better, while wider tires offer enhanced traction and stability on paved roads. Choice of tire size also impacts fuel efficiency and load carrying capacity.

The 1992 Chevrolet Suburban (GMT400) is quite large, with length up to 5588 mm (219.9 inches), width up to 1956 mm (77 inches), and height reaching 1910 mm (75.2 inches) depending on configuration. Most standard residential garages measure approximately 2438 mm (8 feet) wide and 4877 mm (16 feet) deep, with ceiling heights around 2133 mm (7 feet). Due to its length and width, the Suburban might fit into larger garages but may be tight or require precise maneuvering in standard-sized garages. The height, especially for models close to 1910 mm (75.2 inches), could also challenge garages with lower ceilings or overhead storage. Owners should measure their garage spaces carefully or consider modifications if garage parking is needed.

Compared to its predecessor, the GMT400 generation Suburban (1991–2001) was slightly larger overall. The previous generation, produced until 1991, typically measured around 5600 mm (220.5 inches) in length but was generally less refined in weight distribution and interior ergonomics. The GMT400 introduced increased width—up to approximately 1956 mm (77 inches)—offering improved passenger space and cargo area. Height adjustments also led to better ground clearance and off-road capability. The curb weight increased due to added safety features and structural reinforcements, benefitting durability but slightly affecting fuel economy. The GMT400 generation presented a clear evolution in size and utility from its predecessor.

The 1992 Chevrolet Suburban (GMT400) stood out among full-size SUVs of its era due to its substantial length (up to 5588 mm/219.9 inches) and robust maximum weight rating (up to 3901 kg/8599 lbs). Compared to competitors like the Ford Excursion or Dodge Ramcharger, the Suburban offered a notable balance of passenger capacity, cargo volume, and towing capability. Its width (up to 1956 mm/77 inches) provided stability and interior room, although some rivals sometimes featured slightly wider or taller profiles. Overall, the Suburban's versatility as a full-size SUV made it a preferred choice for families, commercial users, and those requiring serious hauling or off-road performance.

Thanks to its considerable length and width, the 1992 Chevrolet Suburban (GMT400) delivers substantial interior volume. It typically seats up to nine passengers with three rows of bench seats, providing generous legroom and headroom, aided by height up to 1910 mm (75.2 inches). Cargo space behind the third row is ample for luggage or equipment, with even more capacity available by folding the rear seats down, turning the Suburban into a sizeable cargo hauler. This configuration makes it practical for large families, group travel, or hauling bulky items, highlighting its role as a versatile SUV.

The large size of the 1992 Chevrolet Suburban (GMT400), with its long length (up to 5588 mm/219.9 inches), wide body (up to 1956 mm/77 inches), and heavy curb weight (up to 2590 kg/5709 lbs), naturally affects fuel economy. This full-size SUV typically delivers lower miles per gallon compared to smaller vehicles, especially in city driving conditions where frequent stops and heavy loads take their toll. Additionally, its size can make urban maneuvering and parking more challenging, although its elevated driving position aids visibility. Despite these factors, its size offers considerable benefits in passenger comfort, cargo capacity, and towing, balancing usability for drivers who prioritize space and capability over fuel efficiency.
