Rough country 4" Long arm kit
Now on to what's in the queue:
I've ordered 4.88 gears an overhaul kit and Detroit Truetrac for the rear, my thought process being that I'll and get a set of used 33" or 34" A/T',s drive it around on pavement/highway in 2wd for a little bit to make sure this is the ratio I want to run and work out the bugs. If I like it do the same to the front.
I know this size tire will wear out/beat on and break my stock axles! I anticipate this and don't really know what direction to go in on that just yet but for now I need this jeep on the road! It's not a DD but for one reason or another, all the work I listed has taken the better part of 2 years to complete and the vehicle was parked for all that time! I refuse to have the thing sitting on jack stands any longer. In fact Iíve been driving it every day to work, I love driving it! That doesnít mean I wonít take the time or $$$ to do things right but I love driving this Jeep, Jeepers see the stick shifter in the console and go holy ****! Conversations ensue and it's just an all-around fun Jeep
On to where I am headed with this
My questions are the steering is obviously going to prove inadequate, I see a lot of back and forth on this forum about various upgrades, the ORO U-Turn kit, Currie Kit, WJ swap... Some people swap Durango steering boxes in. I am not sure what direction to go in but I want to order 1.5" pucks for the top of the coils and get a little extra lift and I will prolly leave lift height at that.
What makes sense for a steering setup? Drop pitman arm, tougher steering box? Brace? Linkage? Knuckles? I want it to be a really capable Jeep, but it needs to be reliable and most of all highway speed safe. My goal is not to build a beater rock crawler, to me this Jeep is too rare and means too much to me to trash itÖ I plan on wheeling it and have already tried it out on the trail with the lift in, it did very well! But Iím not one to flog the piss out of her. Also will the extra inch and a half really throw this whole thing into disarray?
I think the front trackbar with its new drop bracket is adjustable enough to compensate for the extra lift, the rear is stock with drop bracket so there may be issues there.
Also I prolly need bigger front brakes right!?

Reason: Title Change
I know, im just waiting until it breaks (and it will) to replace it. The axles I want to have a seperate discussion on later in this jeeps life, since we are talking 1000's there! Is there a brand (trackbar) people have success with in the 4-6" lift range?
my buddy has an IRO double shear TB on his XJ (same front suspension as ZJs) and he likes it. i installed it for him, it seems pretty beefy. not sure what lift heights it can go to though. he's on 3 inches
Reliability is relative
Well the front track bar that came with my kit is good 4"-6" but thats good to know thanks, I never heard of IRO til last week but the rear track bar is more what im looking for a vote of confidence on. It says good 0"-8" and seems reasonably priced. Also hoping someone has advice on steering upgrades...
Good referral on the JKS Rear Trackbar that unit looks tough as well! You say your running the currie steering setup... Is that the XJ steering system? I don't see a ZJ system listed on their website. It also looks like that still keeps the "dreaded" inverted y design the ZJ forum FAQ says to avoid when going above 4".
Yeah, the XJ/TJ one. Fits on the ZJ, don't know why they didn't list it. I have a slight dead spot, but I'll trade that for strength any day (I can jack the Jeep up off the tie rod and it won't flex), it is alos VERY easy to service. Ripped a grease boot, had it swapped out in under 10 minutes.
Grab a steering box from a mid 70's GM 4x4 its a Saginaw box. It will have a "76" stamped on the bottom of it. Its also beef and I have heard its a bolt in application. Id pull on from a JY if you can. Thats what I plan on doing when I get my bigger tires.
Hey thanks dude! Yes that 8.8 is a tad narrower than stock ZJ axles. I got rid of ABS when I did my swap. I have heard you can keep it but I just didnt want to mess with it. Im at 4.5" ...I dont care to talk about my current tires as I hate them with a passion. I had a set of KM2's in the 31" flavor.
