TJ · 1997–2006
Round headlights return, and the frame learns to flex
The TJ replaced the square-headlight YJ with a deliberate heritage move — round headlights explicitly recalling the CJ and original MB — while making the single biggest chassis change in Wrangler history: coil-spring front and rear suspension in place of leaf springs, transforming both ride quality and off-road articulation. It is also the generation that introduced the Rubicon trim, now the name for Jeep's most serious factory off-road package across the whole brand.
United States market, all trims (SE, Sport, Sahara, Rubicon). Model-year running changes noted where sourced; non-US variants are out of scope for this profile.

Configuration
Trims and transmissions
The Rubicon trim launched for the 2003 model year, named for the Rubicon Trail (see /off-road). It paired Dana 44 axles front and rear with selectable locking differentials and a 4:1 transfer-case ratio — hardware calibrated for extreme articulation, not everyday street manners. SE models used the 2.5L (1997–2002) then the 2.4L (2003–2006) as standard; the 4.0L I6 became optional even on base trims for 2005–2006. The 3-speed automatic was replaced by a 4-speed 42RLE overdrive automatic starting with the 2003 model year, regardless of engine choice.
Identify & buy
Identification and ownership notes
TJs fall entirely within the standardized 17-character VIN era (see /decode/vin) — position 10 resolves to model years 1997–2006 on the modern letter cycle. The most important TJ-specific ownership check is not on the VIN at all: frame rust at the rear control-arm brackets, which rots from the inside out because the frame's center section has no drain holes. See /buyer-guide for the full inspection technique.
