1949 Jeep CJ-3A Dimensions, Size & Specs

The Jeep CJ-3A from 1949 has a curb weight of approximately 1,134 kg (2,500 lbs). This relatively lightweight build enhances the vehicle's off-road agility and fuel efficiency. The light weight allows for better handling on uneven terrain, making it easier to maneuver in challenging conditions such as mud, snow, and rocky trails. Additionally, the lighter mass means reduced suspension stress and can contribute to longer component life. However, the vehicle's weight also reflects its utilitarian design, without many heavy luxury features, emphasizing practicality and durability over comfort.

The Jeep CJ-3A features a ground clearance of approximately 220 mm (8.7 inches). Ground clearance is critical for off-road vehicles as it determines the vehicle's ability to pass over obstacles without damaging the underside. A clearance of about 220 mm allows the CJ-3A to navigate rocky paths, roots, and uneven surfaces effectively. This height strikes a balance between stability and off-road capability, ensuring the vehicle remains stable while climbing or descending uneven terrain while maintaining access to hard-to-reach areas not accessible by standard vehicles. That makes it a true pioneer among early off-road civilian vehicles.

The 1949 Jeep CJ-3A, with a length of 3,340 mm (131.5 inches) and a width of 1,575 mm (62 inches), fits comfortably within the dimensions of a typical single-car garage, which usually measures around 6,000 mm (20 feet) in length and 3,000 mm (10 feet) in width. Its compact size means owners have ample space for maneuvering and storing other items alongside the vehicle. However, because the Jeep's height is approximately 1,750 mm (69 inches), a standard garage height clearance of 2,100 mm (7 feet) or more is recommended to avoid any tight squeezes, especially if a roof rack or accessories are installed.

The Jeep CJ-3A was designed primarily as a two-door off-road vehicle with seating for up to two or three occupants, depending on the configuration, which was common among similar vehicles of the late 1940s. The interior focused on durability and practicality rather than luxury, featuring basic seating and minimal creature comforts. Compared to other off-road vehicles of its time, the CJ-3A offered relatively modest interior space but excelled in ruggedness and functionality on rough terrain. Its compact cabin and minimal fittings prioritized essential off-road utility, making it less spacious but highly effective for adventurous and utilitarian purposes.

The Jeep CJ-3A is a direct evolution of the CJ-2A and retains a very similar size profile, but with subtle improvements in design and functionality. Both vehicles measure closely in length, with the CJ-3A at approximately 3,340 mm (131.5 inches) versus the CJ-2A's around 3,300 mm (130 inches), and width and height remain nearly identical. The CJ-3A introduced enhancements like a reinforced frame and an updated electrical system, but dimensions remained compact to preserve off-road agility. Thus, while the CJ-3A featured modernized mechanical and ergonomic aspects over the CJ-2A, its physical footprint stayed essentially the same to maintain maneuverability and compatibility with off-road applications.

The Jeep CJ-3A is equipped with a fuel tank capacity of roughly 28 liters (7.4 US gallons). This modest capacity was sufficient for the vehicle’s intended utility and off-road use, providing a reasonable balance between weight and range. Given the CJ-3A’s moderate fuel consumption and lightweight design, this fuel volume allows for decent travel distances before refueling, which is beneficial during remote off-road trips. Still, for prolonged adventures or rugged terrain where fuel stations are scarce, it is advisable for users to carry additional fuel in approved containers to ensure sufficient supply.

In the landscape of late 1940s off-road vehicles, the Jeep CJ-3A stood out for its compact and rugged design, optimized for both civilian and military use. Compared to competitors like the Willys M38 or the Ford GPW, the CJ-3A maintained a similar size—roughly 3.3 meters (about 131 inches) long—while emphasizing durability and simplicity. Its off-road capability was enhanced by a sturdy four-wheel-drive system and a higher ground clearance, essential for tackling challenging, unmapped terrain. Many contemporaries were either larger or less capable off-road, making the CJ-3A an ideal choice for farmers, outdoorsmen, and military personnel who valued a versatile, manageable vehicle with a compact footprint.

The 1949 Jeep CJ-3A features a compact body measuring roughly 3,340 mm (131.5 inches) in length, 1,575 mm (62 inches) wide, and about 1,750 mm (68.9 inches) tall. Its boxy, utilitarian exterior with a short wheelbase facilitates tight turning radii essential for navigating difficult off-road environments. The durable steel body and minimal overhangs reduce the risk of damage on rough terrain. Combined with its solid axle suspension, high ground clearance of 220 mm (8.7 inches), and light curb weight of 1,134 kg (2,500 lbs), these dimensions create excellent approach and departure angles. These factors collectively ensure the CJ-3A remains a legendary vehicle for trail access and rugged use.

The Jeep CJ-3A, produced starting in 1949, was a refined update over the CJ-2A, carrying forward much of its size and shape but introducing several important improvements. While the exterior dimensions stayed close—approximately 3,340 mm (131.5 inches) in length and 1,575 mm (62 inches) wide—the CJ-3A featured a reinforced structure and improved electrical system, increasing reliability and usability. Size-related changes were subtle but purposeful, aimed at enhancing usability without sacrificing the excellent off-road agility. The new model also benefited from improved ergonomics and slightly better weather protection, making it a more comfortable vehicle while retaining the compact footprint that made the CJ line so effective.
