Iceland's claims are also using a ZJ with 2-2.5" of trimming to make them fit with an 8" lift, on a WJ if you trim that much you won't need the flares.

If you can find a 242 from a Jeep it will make it a little easier matching the input/ output splines. You can usually find the 242HD in the 2002's.
Lockers aren't any harder on your axle, they just split the power between the 2 wheels so if one lifts the other still has 50% of the available tourque going to it. Slow and steady will get you where you want to go.
I'm not sure about the reference to the QT in your Jeep, when you switch to the 242 your going to loose your AWD.
While your under there, if your going to be crossing water don't forget to extend the vent lines for your axles, trans and T/C as high as you can. Also wire in a toggle switch if you have an electric fan up front so you can kill the power. They don't do well when they kick on under water. Guess how I found out...

the point of 242 is to have more control. you maintain 2wd all the time, shift into awd with a constant 48/52% torque split front and rear. and finaly have high range pt 4x4 mode. HD242 is for more strength. didnt think any jeeps had hd242 just regular 242's. hd242 exclusive to dodge rams, but will check that out. rare in a jeep so will be hard to find.

having 242 retains AWD. had it in my 87 cherokee and loved it.

jeep grands have hydraulic fans running off p/s pump - wierd but true.

lockers are harder due to being locked and turnng. it is well known snapping axles happens with lockers vs open diffs. lsd is limited slip - allowing less stress on axles.

well yeah you have to trim to fit big wheels with small amount of lift. actually on the zj with 6" lift they fit 37"x14.5" tires. and they have 4" lift with 35" tires.

review for yourself. http://www.icelandoffroad.com/index.html

Don't get me wrong, I'm not saying it can't happen BUT trimming 2.5" so you can fit bigger tires your going to have to do on a WJ anyways. THe ZJ suspension is different enough that you can sometimes get away with the larger tires without trimming as much. Spending 500 US for a set of flairs to bandage over a trim job just seems excessive to me. I hope it does work, but I want to see some pics of an actual WJ first. Just take it with a grain of salt until there's some proof out there.
Don't mind me I'mm rambling, been up for over 48 hours and the brain is on auto-pilot.

You also answered your own post about loosing the AWD with a 242HD, you don't shift into AWD you shift into 4HI, big difference. Your locked at the 48/50 split, with AWD it can send 100% to the front or the rear.
242HD's were used in the 2002 and some 2003 GC's, just have to match up the numbers.
Lockers... so many myths about them, yes they do modify your turning radius. Most people when they get a locker installed think that they can now go anywhere and power through. These are the people that usually break axles, TRE's and such.
Pick a line that you know your Jeep is capable of, learn how to turn with it engaged before you get out there, and if you practice "slow and steady" chances are very high that you won't break anything.
Not sure what you have for an engine in yours but if you have the factory trailer package they usually toss in an electric fan in front of the mechanical fan. Mine isn't run off the PS hydraulics, it's spun by the serpentine belt.

How about that, I just looked in my manual and I never realized the 4.7's fan was run like that! Guess I'll have to take a closer look at my buddy's 03.
I wonder how many ponies you lose with it slaved together like that.

I have ran a locker before. I have met many others who do as well. it is not a myth. when the locker kicks in and locks up the axle while turnning this puts pressure on the axles that you dont have with an open diff. the tire the tires have to slip but if they dont then you have a broken axle. Your right great care is needed, especially on the street. do a uturn and hit the gas is a good way to put undue stress on your axle.

242 shift pattern is = 2wd - PT 4WD - AWD - N - PT 4WD LOW

if you are in AWD that is for dry pavement driving. the torque split is variable. much like an open differential the Transfer case is not locked up as it is in PT 4WD. Try this some time. Put a small bottle jack under one corner of a 242 equiped jeep. with it shifted in AWD the one wheel will spin and vehicle wont move. put it in PT 4WD drive and the vehicle will drive forward.

now do this again with the two wheels in the air, one front and one rear. with the vehicle in PT 4wd and the vehicle will not drive forward.

Both examples are assuming the axles do not have LSD or lockers and are just open diffs.

WJ Flares, 4" lift and 34" tires. claim is that with 4.5" tires that 35's fit.
as far as trimming goes and cover up with flares - the point of the flare is to be legal with different backspacing of the wheels. the cutting is not cutt and leave bare metal. you do a proper job with welding in a new lip. I have done this on a XJ before. stock lift with 2" boost and I fit 33" tires. wheeled really well.

to each their own. if done right, the cut and small lift is smarter for many reasons. main one is to stay away from skyhigh lift to create a unstable, rollable vehicle. backspace of wheels help in giving back stability.

I agree with what your saying ssnipes, BUT the 242 doesn't have AWD. Your confusing 4FT with AWD.
It may be trivial but,

AWD T/C- No driver input required, input/ output shafts not locked in position. Will automatically send power to front or rear axle or side to side depending on which model. Transfer ratio is 0-100% to either axle.

242 T/C- Driver input required, rear output shaft constantly locked if not in 2wd position. T/C will only send a MAX torque of 48% to the front axle through the extra diff located in the T/C.

About lockers, if you've run them before then you'll know yourself that there is a ton of misinformation out there about them. Usually posted by some guy that had a friend that had a friend...
I love lockers, the trick to using them though (in MY opinion only) is lock it when you need to and then unlock it. Lockers to me are like recovery gear, use it only when nessessary. Like I stated before, pick a line that you know that your capable of and stick to it. When I'm off road I pick my lines like I don't have the locker then use it if I need it and I've never broken an axle.
I've found that the majority of guy's that snap axles think that they now have super rig with a locker installed and go where thier really not equipt to go in the first place.
Just a question but why would you be running a locker on the street, are you 1/4 mileing that thing? :)

AHHHH I see.

regarding lockers. You have manual lockers. best thing to have. I agree. If I could afford it I would have it I would. I have had slip-in automatic lockers. work really well but if your not careful it can be stressful on the diff on the street. Off-road the manual locker can still break axles if not careful.

for a 1/4 mile? dont know where that came from but I would definitely have that for launching in a 1/4 mile. But since you did not know I was talking about an automatic locker and you run lockers of my dreams then you perhaps have not experienced a auto locker on the street or offroad.

as for AWD and 4FT. same thing. just different AWD systems out there. for the 242 I am not kidding. Lift any front wheel and you wont be going any where with open diffs. I had it. I did it. that is the way it works. Sure you can have a STI or an EVO X with a very sophisticated AWD system that controls the torque bias. 242 is a AWD system that can be called FT4WD but it is just that - any wheel can have 100% torque or 0% torque. Try it and share your results. it has to be a system with open diffs and a 242. If you dont try it then I guess we will have to agree to disagree.

wish you were closer! we would have a ballin time offroad
