Xj Introduction:
Introduced in 1984 as a unibody SUV, a departure from traditional body-on-frame Jeep construction, designed for better on-road manners and fuel efficiency.
Yj Introduction:
Introduced in 1987 as the successor to the CJ-7, featuring updated styling and coil springs in the front suspension (distinct from the XJ's unibody design).
Xj Updates:
Significant updates included the introduction of the 4.0L HO engine (1987), interior and exterior styling refreshes (1991), and the addition of airbags (circa 1994).
Production Period:
1984-1996
