1997 marked the end of the YJ era and the start of another period of Jeep evolution. Jeep's tried and true leaf spring design was retired in favor of a four-link coil spring design. While Jeep purists initially scoffed at this break from tradition, the TJ's amazing offroad performance, and much improved on-road drivability, eventually won over most skeptics. Properly equipped, a TJ can be an enjoyable daily driver and a very competent off-road machine. This is no small accomplishment! The TJ 4-link suspension design is much like that of the mid-size XJ series Wagoneer / Cherokee. These vehicles use a track bar to locate each axle left-to-right, and the four-link arms to locate the axles front-to-rear.
