Here's what I would like to see in an KJ FAQ sticky thread. These questions are asked about once every other week.

What is the difference between lowered and prelowered?

What lifts are available for the KJ?

What is the largest tire size that will fit without rubbing (with and without a lift)?

What changes have occurred between the 2002 and (present year model) KJs?

OK, great! I know that the KJs were lowered 3/4" in April '02, which is the lowered/prelowered designation and makes some difference in tire fitting/lift results. I'll stick that in there along with some lift info and tire charts.

I have no idea on all of the changes for the KJs from '02 - '05. I'm still learning about all the TJ changes and working on that FAQ as well.
Thanks for the help!

Oh, I also tossed in some traction device info as well.

another thing is most people dont know when to use 4WD, or 4lo for that matter. (which weather/environment conditions must be present)

PA_KJ 11-30-2004 02:33 PM

Your missing the following available lift kits:

All J Products Frakenlift 2.5" lift kit: http://www.boulderbars.com You have to ask for it. It's not listed on the web site.

BDS Suspensions - 2" front/1.5" rear lift kit: http://www.bds-suspension.com

Revtek spacer 2" lift kit: http://www.revtek.com

Skyjacker Platinum Coil Over 2.5" lift kit (LIB250K): http://www.skyjacker.com

Skyjacker spacer 2.5" lift kit (KJ25): http://www.skyjacker.com

Teraflex spacer 2" lift kit


Additionally, a couple companies are developing large lift kits:

RockKrawler 7-up long arm lift kit: http://www.rockkrawler.com/ A picture of a 7-up equipped KJ is currently on the front page.

Superlift 4.5" lift kit: http://www.superlift.com This lift is not listed on their site either. It is probably still in development.

Some more detailed information on the difference between lowered and prelowered...

All KJs produced prior to April 2002 are considered "prelowered". All KJs produced from April 2002 on are considered "lowered". Autoweek magazine rolled a 2WD KJ in a slalom test so fearing the potential fallout DC started lowering all KJs 22mm (0.87") in the front and 19mm (0.75") in the rear. There were several different front suspension set ups used throughout the earlier years so there may be several different heights for 2002s and 2003s.


Some information on model changes...

Which model year KJ rolled over in their test?

It was a 2WD 2002 Sport. Consumer Reports tested a 4WD 2002 and gave it a "thumbs up".

LibertyV6 12-03-2004 01:55 PM

I'll read that link when I get back from work tonight.... Did the 4WD one pass because it was a heavier vehicle than the 2WD---- or because the driver engaged 4-HI in the 2nd test?

Meister 12-04-2004 10:16 PM

it is probly a little late for me to be asking this, but how did the 05 2wd do in roll over tests?

Slipslap 02-07-2005 08:04 AM

Heres a site I found for KJ parts. They have plenty of other Off-Road parts, but they have a nice list of KJ stuff. And their products seem ok from I gather. Well here it is Rock Road Outfitters Not sure if it's been mentioned before. If anyone knows anything bad about them let it out.

I don't think anybody mentioned the tranny change. something like a 45 tranny and a 42 tranny. I don't know all the details.

The '02 had the 45RFE and was switched to a 42rLe (same as '03+ TJs) in '03 based on this link.

I guess I should probably add that to the top, huh...

Additions to the FAQ
 
Also worth adding, is that the 2005 CRD - despite what the "specs" say - comes with the 16inch ("Mechanica" - optional on Liberty Sport models) wheels and 225/75/R16 tires....

And that the 2005 models have a new plastic kick plate.

And possibly that the Renegade models have different hoods and front grills... (flatter hoods, bigger grills with no fog lights, as they are on the bumper (and a slightly different bumper as well))

clicktracy 09-12-2005 06:41 PM

In Oz we have a 2.5 I4 Turbo Diesel and I read somewhere that CRD stands for common rail direct
