The Wrangler YJ used a 2.5 L AMC 150 I4 or optional 4.2 L AMC 258 I6 until 1991. That year, a fuel injected 180 hp
(134 kW) 4.0 L AMC 242 variant replaced the 112 hp (84 kW) 4.2 L 258 CID straight-6. The NP207 transfer
case was used only in 1987 and replaced by the NP231
The roll cage was extended in 1992 to allow for rear shoulder belts, and anti-lock brakes were added as an
option the next year. An automatic transmission option for 4-cylinder Wranglers came in 1994 along with a
center high-mounted stop light. In 1994, the slave cylinder on manual transmissions was moved outside of the transmission's bellhousing to
allow for easier replacement, and in 1995 larger U-joints were used.
