Sway Bar Pop

[Flyguytki]

4'' Lift with bilsteins at 2.1

I had a pretty bad pop quite often so i replaced the nuts on the sway bar and tightened them as instructed just until the spacer starts to bulge. I am still getting a pop every once and a while. Should I tighten them more? Or could it be more serious and require longer sway bar links due to the bilsteins?

I have a 6" RCX lift and I just recently had Bilstein's installed at the same height, 2.1.

I am also getting the pop sometimes when turning sharp and driving.

I'm interested what the fix is as well.
