The Jeep TJ succeeded the YJ in the 1997 model year. The TJ features a coil-spring suspension, a design carried over from the Jeep Grand Cherokee which gives the TJ a better ride and better handling. The round headlights of the CJ returned as well. In the engine room is the familiar 4.0 L Straight-6 used in the Jeep Cherokee variations. An optional 2.5 L Inline-4 was offered through 2003, but beginning in 2004 a 2.4 L Inline 4 engine used in the Doge Neon replaced it.
