Cherokee Stock Specs
Common Design All XJs were built as a "Unibody" design with the body and frame rails tied together as one piece as opposed to a body on frame design. All XJs have solid axles front and rear. The suspension is coils/leaf springs. All XJs came with disc/drums brakes. Dimensions (small differences may occur depending on optional equipment or trim level) wheelbase = 101.4" overall length = 165.3" - 168.8" overall width = 67.9" - 70.5" track = 58" height = 64" height with roof rack = 66.8" ground clearance (from differentials) = 7.3" - 8.3" approach angle = 37.6* - 38* departure angle = 31* - 32.1* breakover angle = 21* - 21.9* curb weight 2wd = 2,891 lbs - 2,993 lbs curb weight 4wd = 3,057 lbs - 3,386 lbs cargo capacity = 71.0 cu ft. Body The body comes in both 2-door and 4-door styles with a rear hatch (liftgate). In 94 side-impact beams were added in the doors and roof was strengthened. The 3rd brakelight was added to the top of the liftgate. In 96 the body structure was strengthened some although it was not noticeable in appearance. In 97 the body (and interior) was redesigned to freshen it up a bit. Most noticeably it gave the body smoother lines by changing the bumpers, flares, and moldings. The front fender was trimmed just below the headlights and replaced with plastic bumper endcaps that wrap around to the wheel well. The liftgate was also changed from fiberglass to sheet metal in this year. The windshield washer bottle was also moved to the inside of the drivers side front fender.

Common Design
All MJs were built as a full unibody design with the body and frame rails tied/welded together as one piece and cannot be removed, however, the rear is a fully boxed frame with the bed bolted to it, making the bed removable. All MJs have solid axles front and rear. The suspension consists of coils for the front and leaf springs for the rear. All MJs came with disc brakes in the front and drums in the rear. Also, all MJ's through all years are equipped with a height sensing proportioning valve that is used to change the bias of the brakes if the bed had a load in it. For those curious to the differences in Cherokee's and Comanche's: The taillight lenses are different from a Cherokee's, the wheel flares are the same (as a 2dr Cherokee), hoods are swappable from 84-92 models Cherokee's (Cherokee's above 92 used spring-loaded hinges), and all mechanical/electronic parts forward of the firewall ARE identical. Body The body comes only in standard cab model with a rear double-top hatch tailgate. Comes in longbed or shortbeds two-tone versions. Long bed versions come with a larger gas tank than the short bed and is located front of the axle. Short bed version was not avaiable in 1986. Interior: Door panels are removable as stock. Bench seats and bucket seats DO NOT have the same mounting brackets as XJ seats. Gauge cluster is removed by 4 screws. Gauge cluster during 86' have mechanical-powered gauges. On 87-90 gauges, The speedometer uses a cable, but all gauges 91-92 use a computer cable.
