Front track bar: Currie or JKS?

So to confirm, the Moog k3147 should be the better bushing to replace the axle side bushing on the currie trackbar, correct? And theoretically I should just be able to press the old one out and then press the new moog k3147 in?
Sounds good. My bushing is fine still, but it couldn't hurt to have a spare on hand since mine is a little cracked but nothing major.
They likely make a JJ that will fit but then we have the same problem as others, how to stop the bar from flopping around.
Couldn't that easily be solved by simply using a washer and bushing with a smaller ID hole to restrict the movement of the ball?
To stop the bar from flopping. I'm not saying that a JJ would be better than a bushing on the axle end. I'm just answering the question of how you could use a modified JJ on the axle end and still keep the bar from flopping. Whether or not that actually serves a real purpose can be debated by others. I don't really see that need.
I have wondered why they couldn't solve the front the same way they did the rear with the wobble stopper washers. But I've also never seen a rear Currie track bar in person to see how much they restrict the flopping.
The big issue with the rear one is if it flops back, it can get under the crossmember and do some damage.
I run a 4" lift with a Currie bar on the front and JKS bar on the rear. I bought the JKS because I was price shopping and it looked like it would work for me. I have been satisfied with the JKS in the rear. I bought the Currie front track bar a year later, By then, I had experienced some drivability issues and wanted to do things just one more time. The main difference I remember about the Currie bar is that the hardware is bigger and I had to drill out some holes. I considered that a good thing. I don't have a photo of the frame mount side, but I have this one that shows the complete front.
I don’t. The bushings are shot and I cannot find the correct ones for the rear other than replacing the whole bar. Which I can...but the single element vs dual element discussion me think there is a better solution instead of replacing the whole bar.
I can now confirm the bushings for the rear track bar are the same as the front. If I were gonna replace the rear track bar, I’d just replace the bushings. I ordered a rear track bar and then front bushings and it was the same model number on the existing front bushing and the new rear.
I would suspect so. The bolt goes through and then clevite model number is the same.
I didn’t press it out to see, but the two bushings are exactly the same. If I know now, I would order the k3147 for the two rear track bar bushings. If you want, I can take some side by shots.
Thank you for the update. I have the k3147 on order for the front. I'll see if I can add additional confirmation for the rear. If the bolt holes are the same and everything looks good like your finding, I'll order a set for the rear bar. I'll try to get back to everyone with my results.
I will add a note on the Moog trackbar for the front. Although it uses cheaper bushings, it still appears to be a solid bar with the same curves as the stock trackbar. As a bonus, they are about 1/4 longer than stock. So the Moog front trackbar makes a nice replacement if you have a small lift. But I do wish the frame side had a replaceable end.
