Welcome to the Jeep Comanche web site.
I tried to get as much information and functionality on this web site as
possible for you jeep Comanche fanatics.
This model truck was designed from 1986
to 1992. In my opinion, this jeep truck was, and still is an awesome
vehicle. In it's day the Comanche was the king of the compact pickup.
It's style was discontinued because Chrysler already had put most of
their time and money into other trucks. If you search on the web today
it is very difficult to find anything on the jeep comanche. So far I
found only a few pages with some nice pictures with some
jeep performance chips for trucks.
