I guess i need a new rear track bar since my 3.5" lift has caused my drivers side rear tire to scrape against my spring perch on occasion.

wow ... your axle must be off center a lot!
If you have a rear TB relocation bracket and stock TB in the rear you should be fine with around 3" lift,
BUT if you have a fresh RE 3.5 lift ... well hehehe ... their springs give you quite more than 3.5 AT THE BEGINNING (around 4" point something) ... they might settle down to ~3.5 after a while.

And/Or you are running wheels with close to stock back spacing ... (5.5")
wider tires require less backspacing ... the usual range is 4.5" to 3.65".

so : an adjustable in the rear gives you some flexibility over your lift life cycle

well i have 33/12.5" on stock 16" Rubi wheels, and there is about 1/2" clearance on the drivers side, and 1.25" or so on the pass. side between the coil spring perch and the tire. I can see evidence of the tire rubbing on the drivers side on occasion. i'm not sure what I'll do to fix it yet.

the adjustable isn't exactly a good idea in the rear without a relocation bracket and shocks longer than 8.5" travel.... at full droop they bind on the stock bracket and can cause failure, like ripping it off the axle.



RE adjustable....



jks adjustable

that's what happens using stock backspacing with 11.5" wide tires and no rear track bar relocation.... or wheel spacer, which is also an option but is far more expensive than a 35 dollar track bar relocation bracket.

I just saw an adjustable track bar on a 2.5" ome lift with the n66 shocks, no bumpstop extensions, stock control arms, correct pinion angle, d30 stock diff cover, and centered axle not hit the trackbar on the diff cover. Im fairly certain it went to full bump with both front tires at the same time too, Theres not a hint of any contact on the diff cover, axle where bushing might hit, or the track bar.

It's a jks adjustable track bar, and it appears to be bent foreward to where it has plenty of clearance from the diff under full bump. I saw other pictures of the same or similar jks trackbar hitting in this thread, but this one doesnt. This leads me to either one of the two following conclusions reguarding the jks trackbars that were shown hitting in this thread. Either A: the suspension in the pictures with the trackbars hitting wasnt aligned properly, this particular rigs mounts might have been off from the factory (I have heard of jeep not being precise with the placement of mounts when building) or a combination of both.

So sounds like there is definatly hope for an adjustable track bar that works for under 3" of lift.

cool ... but do I want to "find" out ? Honestly : NO

btw I am wondering how the front pinion angle is parallel to the front TC OUTPUT yoke with the stock control arms with front sitting 2.5" higher than stock ... thats why I put adjustable front lowers to push my front diff a bit forward to have the front pinion angle LOWERD again.
Which of course increases the risk of hitting aftermarket TBs
(A slightly extended front wheel base is not bad at all with lifted Jeeps ... noticeably less harsh driving over small obstacles! Ahh ... the caster is then better as a nice side effect )

oops ... somehow I was assuming he was using the TB relocation bracket already ... I really read the whole thread and saw those great pics posted before ... thanks a lot mudb8!

The knowledge and experience coming from a handful senior members in this forum make it so valuable ... how many bellies of different TJ builds did you see i your life?

I only saw my TJs belly close enough ...
I compensated the lack of first hand "experience" by thorough fully reading!
(many threads are worth it from start to end!)

Wow, Mudb8, that signature is a post unto itself. Reading your last post I got to the sig and kept going, the whole time wondering how it was relevant to the topic.




And you just won't stop scaring me about these adjustable track bars. Luckily my 8.8's bracket is open at the top.

Parallel? The diff yoke should be in line with the driveshaft. It's a cv shaft...

I'm not sure what you mean by parallel, but the stock arms with the cam bolts work just fine for correcting pinion angle...

you are right ...

I dunno what I was thinking ... actually my front pinion angle is pointing towards the TC output yoke ... parallel to the main shaft ... maybe barely noticeable below but for sure not higher. The discussion caster versus pinion angle must have confused me at some points ... I mean I might have read somewhere that the TJ front DS is not really CV type or so ...

caster angle is reduced the more in line the the d-shaft is along with the more likelyhood of having the diff crash into/scrape the Track bar at full stuff.

basicly, 4* of caster has a near perfect driveline angle for a 3" lift but has the top of the diff in a bad position for a short lift and short or no bumpstop extension, not to mention makes a squirley driving TJ. 7* caster is still in a good position without vibes with a stock 03/up skid and has the top of the diff tilted inward and away from the track bar/brackets...

prime example from the use of a Fabtec front relocation bracket....

wow, great thread mudb8

i'm so glad i put off installing the JKS OGS126 in my tj. i'm just going to redrill the mount and have it welded

any idea if it will be fine for an XJ with 3" of lift and trimmed fenders? the xj won't see any trails just beach/dunes and roads. i'm going to extend the bumpstops 1" and see if they clear and add more if needed. building the jeep for my dad so i want the axle to be centered. it may get 31x10.5s and/or new wheels with less backspacing depending on the budget

it still needs to be cleaned up and repainted but i was just trying to get an idea of the ride height, i may trim some more as well. it's quite fun

the xj will still need to be bumpstoped, first of all, according to the shock length.... which means the 2" extensions will make way for the JKS track bar.


Nothin wrong with a little cuttin! but that's another topic for another thread.....

Will the stock trackbar accommodate the extra flex (and droop) you'll get with a 2 or 3 inch lift when using that drop bracket?
