1987-1995 Jeep Wrangler YJ

Background

The Jeep Wrangler YJ was introduced in 1987. In 1988 some minor changes were made including the way the upper half doors attached to the lower half doors. Little changed for Wrangler YJ jeep parts in model years 1989 and 1990. Starting in 1991, the 4.2 liter in-line 6 cylinder engine was upgraded to the fuel injected 4.0 Liter High Output engine which remained in Jeep Wranglers for the next 15 years. In 1992, the classic roll bar was changed to the more elaborate cage which provided the Jeep Wrangler YJ rear passengers with greater protection. With the exception of minor interior and trim details, Wrangler YJ Jeep parts remained unchanged in model years 1993, 1994 and its final production year 1995.
