2018 Jeep Wrangler IV Unlimited (JL) Dimensions, Size & Specs

The width of the Jeep Wrangler IV Unlimited (JL) varies between 1875 mm and 1894 mm (73.8 to 74.5 inches). This relatively wide stance contributes positively to on-road stability, especially on uneven terrain, offering greater control during cornering and off-road adventures. The robust width also enhances interior shoulder room, improving passenger comfort. However, the wider body can present challenges when parking in narrow urban garages or tight parking spots. Despite this, the Jeep’s design retains classic off-road utility while balancing urban usability.

The Jeep Wrangler IV Unlimited (JL) stands between 1838 mm and 1892 mm in height (72.4 to 74.4 inches), depending on the model and specific configuration. This taller height provides excellent headroom for occupants, making cabin space comfortable for adults in both front and rear seats. Additionally, the ride height, or ground clearance, ranges from 242 mm to 274 mm (9.5 to 10.8 inches), which is a crucial factor for off-road performance. The high ground clearance enables the Wrangler to navigate rough terrains, rocks, and obstacles without damaging the undercarriage, maintaining its reputation as a capable off-road vehicle.

The curb weight of the Jeep Wrangler IV Unlimited (JL) ranges between 1903 kg and 2334 kg (4195 to 5144 pounds), depending on trim level and options. This weight is relatively high, reflecting the vehicle’s robust steel body, off-road hardware, and larger frame. While the heavier weight may slightly decrease fuel efficiency compared to lighter SUVs, it contributes positively to stability and durability off-road. The Wrangler is engineered to withstand rough conditions, with its weight aiding traction and control. Overall, the weight supports the rugged nature of the vehicle while slightly impacting fuel economy in urban or highway driving conditions.

The Jeep Wrangler IV Unlimited (JL) offers a luggage capacity of 548 to 784 liters (19.3 to 27.7 cubic feet) with the rear seats upright. When the rear seats are folded down, this capacity significantly expands to between 1059 and 1909 liters (37.4 to 67.4 cubic feet). This flexible cargo space makes the Wrangler very practical for daily use, from grocery shopping to transporting sports equipment or outdoor gear. Despite being an off-road vehicle, the model efficiently balances ruggedness with everyday usability, accommodating moderate to large cargo loads especially when the rear seats are folded.

The Jeep Wrangler IV Unlimited (JL) comes with several rim and tire size options—rims include 7.5J x 17 and 7.5J x 18, while tires vary from 255/75 R17, 255/70 R18, 245/75 R17 to 285/70 R17. These larger tire sizes provide a thicker tire profile that enhances grip and traction on rugged and loose terrains, making the Wrangler highly capable for off-road conditions. The varying tire sizes also offer options for owners who may prioritize fuel efficiency, on-road comfort, or extreme off-road performance, allowing customization based on individual driving needs and conditions.

Standard garage dimensions typically range around 2400 mm (8 feet) wide by 4800 mm (16 feet) deep, with a height of approximately 2130 mm (7 feet). With the Wrangler IV Unlimited's length ranging from 4780 mm to 4882 mm (188.2 to 192.1 inches), width between 1875 mm and 1894 mm (73.8 to 74.5 inches), and height from 1838 mm to 1892 mm (72.4 to 74.4 inches), it generally fits into standard garages in terms of width and height. However, the length is at the upper limit of typical garage depth; this means parking the Wrangler might be tight in smaller or non-custom garages. Extra care is advised for maneuvering inside standard garages, especially with additional accessories such as roof racks.

Compared to the Wrangler III (JK), the Wrangler IV Unlimited (JL) maintains a similar footprint but improves in several key dimensions and features. The JL version generally offers slightly longer length and similar width with modest changes in height depending on trims. These dimension tweaks provide better interior space and updated ergonomics. Off-road features are substantially enhanced, including improved ground clearance options (up to 274 mm or 10.8 inches) and advanced technology like refined suspension systems, better traction control, and updated engines. The JL also incorporates more modern safety and comfort features while retaining the classic rugged styling that the JK was known for.

The Jeep Wrangler IV Unlimited (JL) is often compared with off-road SUVs like the Toyota 4Runner, Ford Bronco, and Land Rover Defender. In size, it is generally more compact in length compared to the Ford Bronco and Toyota 4Runner but similar or slightly larger than some Land Rover Defender trims. Its height and width maintain a balance between on-road drivability and off-road ruggedness. Capability-wise, the JL excels in ground clearance (up to 274 mm or 10.8 inches) and maneuverability due to its solid axle setup and dedicated off-road hardware. While competitors may offer more comfort or modern luxury features, the Wrangler remains popular for its iconic ruggedness, aftermarket customization potential, and trusted off-road performance.
