Trimming that gusset won't hurt a thing as long as it's done in moderation. I've done it on several 9120's to clear up a little room.

14 3/4-15" uppers
16" lowers.

I want your factory 07-up take-off/thrown out JK front/rear Lower Control Arms! Bent ones are perfect also as long as the bushings and cold cut rings are in good shape/useable

That should solve most of the issues. You'll probably find a new limting factor, but if you can get down to ~1-1.5" bumpstop extension with that setup you're doing just fine. With a 1.25" BL, that'll clear 33s.
Adjustable JKS arms are in the works. For now, I will trim the gusset, take pics, and post the results on Sunday. Thanks.

nothing major. I run them. they don't adjust shorter than stock (15.75"), which can be an issue for the rear axle position w/ CV shaft. they are far beefier than necessary for most folks and are more expensive than other options.

Clayton Off-Road is another good option I forgot to mention too. but last I heard a few years back, their lowers didn't adjust shorter than about 16" either, but maybe they have since changed that. i know their front lowers worked great on a JK I helped setup...but we were lengthening the lowers....

along those lines, it's also worth mentioning Metalcloak's lowers I saw didn't adjust shorter than ~15.75-16" either. but the owner also stated they were working on shortening them up a little (forum news?).

if it's too long you can cut em, if you do it carefully. the Savvy double adjustable stuff I've seen had the most adjustment potential with the least fuss. Last I heard they fixed the rear upper length issue with the Currie uppers, so Currie's also a good option.

....so that's the long answer for why I usually recommend that stuff first.

What's wrong with JKS, besides the price? Which control arms would fit a 2" lift? Thanks!

Thanks for the info. Oh, and I use the Rokmen control arms, too.

they use a sort of threaded pivot along the long axis. Teraflex tried that early on many years ago....and it resulted in some well known failures. constantly working threads every time the axle moves doesn't sound very good, does it?

the arms also do nothing to address the way in which the axle moves - the arms are not only required to twist, but they're also required to allow lateral misalignment because the track bar pulls/pushes the axle to one side or the other during the suspension cycle. that's what flex joints do - allow many degrees of movement without stressing the mounting points.

Thanks for explaining the JKS CA's. Would you recommend any control arms for a 2" lift?

By your questions, I probably don't need adjustable control arms. But thanks anyway!

Adding my .02 cents on the subject... I purchased the metal cloak adjustable front track bar a month or so ago and installed it. I have OME 2.5" HD springs, 31" tires, prothane progressive bumpstops cut down to 3.5 ribs for the fronts ( i dont know how else to describe them...they are progressive so exacts are hard to come up with) and bilstein 5100s for a 3" lift. Sorry I don't have the numbers of compression and full extension... I forgot em! Also stock dana 30 diff cover. Anyhow to the meat and potatoes... I put approximately 175 off road miles on the old jeep in the last two weeks with the trail riding being moderate to tough. Big hills, ruts and the like... I will crawl under her and comb over any spots the track bar may have rubbed on and report back!

I doubt you'll find any rubbing. Did you have any trouble centering the axle, ie TB too long?
