JKS...with a 2 1/2 tf lift, no problem.

 

I have the Currie. I like it because it has a Johnny joint on the axle end to allow for better deflection than a rubber bushing.

Jeep has even changed their stock track bars to a uni ball design on the axle end for 2011. So there must be a reason they did this instead of a rubber bushing.

 

I have the Teraflex adjustable trackbar and Teraflex bracket for the trackbar that also has multiple attachment points, it is very strong, very happy with the setup.

 

I also did the Tera 2.5 with JKS adj track bars front and rear and also used there axle side braces
