Has it been aligned since the lift? If not, you need to get that done. Chances are that's what's causing the wobble. IMO, with 2" of lift you shouldn't need to touch the drag link.
You can get an adjustable track bar, but with 2" of lift I doubt you need it. Get it aligned and see what that does for you.
I had the same problem after I put on my lift. It was a combination of bad alignment and track bar bolts that were not tight enough.
