Introduced for the 1984 model year, the Jeep Cherokee XJ sold for nearly two decades and has garnered widespread praise for its dependability, simplicity, light weight, and unmistakable boxy styling—a sharp contrast to the curvy SUVs of its day. Notably, the vehicle was the first non-military 4x4 to feature unibody construction, a design characteristic that has contributed to its reputed durability and exceptional off-road capabilities. Early model year XJs performed well despite running underpowered 2.5L and 2.8L engines, though later variants featuring the more powerful AMC 4.0L /242 c.i.d. engine have become more sought after. In addition to its popularity among off-roading enthusiasts, the XJ was a popular choice for government and police fleets. Consider yourself lucky if you own one of these American classics. Here is a list of some of the most popular aftermarket replacement parts to help you keep it running right.
