and No, not for the rear either. Currie makes, and sells their own rear track bar that uses a JJ + special bracket on the axle side. JKS uses a poly bushing.

Btw, both front track bars hit the stock diff cover without bumpstop extensions. Currie TJS/TJJ model requires 2". JKS requires a bit more. Any aftermarket diff cover besides the Barnett requires even more bumpstop extension.
Again...reading to much into the statement. "counter part" As previously stated,,,same item. I'm not arguing JJ's or bushings. But the SAME counter part. I haven't ordered a trackbar for 2 1/2yrs from either company but the previous ones I've dealt with are indeed the same product. Both JKS and currie do have unique designs and products. I've had and used several of both. The Currie control arms I have in the garage were purchase new 2yrs ago and are the exact same as the JKS arms I've installed on a few TJ's. Products do change, I don't contest that.
To the two companies defense YES....they do have several different versions that are indeed differnent products that anyone can order...but it all depends what you order or purchase. YES..Currie does have designs that are different from JKS's and vice-versa. And you are correct that the two companies are merging further apart. It's good to hear that they are seperating more in design and their newer product.

Also I'm the lucky one of the bunch. My Front JKS trackbar with rebuildable Currie joint...I cant get the thing to hit my diff cover. Luck I guess. I do have 1.5'' bumpstops but that is it in the front. I have installed a few that do hit on aftermarket covers and the covers need clearance or trackbar replaced to cure the issue. Never had any issues with stock D30 or D44 cover with hitting or clearance Issues. ARB covers seem to be the worst for trackbar clearance from my experiance.

What issues have you came into with the trackbar clearance?

A bunch...

old JKS hit the Riddler diff cover, requiring about 3-3.5" of bumpstop. Track bar wouldn't even fit stock, but the Riddler cleared the stock track bar fine.

Contacted JKS, they pretty much denied any problems. Said it was the diff cover, not the track bar, and that I'd moved my axle too far forward. Funny, the pictures were with stock control arms. And the track bar didn't clear stock diff covers.

I now have a custom one-off track bar, similar to the JKS, but with a much bigger bend, and a modified "SOLI" diff cover, which clears with 1-3/8" bumpstop & a ZJ tie-rod. It does rub the tie-rod at full stuff, but only enough to rub paint. But to run a Currie steering (straight across) with this track bar would mean almost 2" bumpstop extension.

here's a good read on the subject:

Thanks for the reply. I hoped this would be the case but I've read on here that it will only rotate the axle, not move it back.

Now I can order just the rear uppers & front lowers.

Thanks again.
