Im hoping that I dont need a custom steering setup when I put my spacers back in, got a drop pitmant arm from rustys, am I good to go without any deathwobble?

Drive it and find out dude, but my bet is your will have no droop, lots of death wobble and a good bit of bump steer. 8" usually takes a lot of other mods to make it work well, not the least of which is raising both the drag link mounting point and likely the axle mount of the track bar. I''m not the biggest fan of the drop pitman arm either because fo the extra stress on the steering box bolts.
Then there is the issue of relocating the frame mounting points for the control arms. The ride usually is pretty rough without this step. Also, without a front locker, if you droop to far, the jeep will try to drive over the front axle and rip it off in the process. Drop bracket or long arms, it isn't cheap or simple.
Good luck

Bump steer will most likely be an issue now. You have lowered the drag link and not it is not parallel to the track bar. A solution here would be to raise the bottom end of the track bar or lower the upper end.
Raising the bottom end would require a new, higher mount on the axle, while lowering the upper end would require a lowering bracket.
It should be raised/lowered an amount equal to the extra drop in the new pitman arm.

Good luck, sounds mean.

Is there a picture in BIG98XJ's post that I'm not seeing? How did you come to the conclusion that the drag link is not parallel with the track bar?

What lift is it? If it's the Tomken 8" kit it *should* have all the stuff to get you by until you can do a custom OTK steering setup.

I'm at 7.5", trailmaster LCA relocation brackets, Rancho 5.5" "extreme drop pitman arm" and still running stock setup for steering. Rubicon express adjustable track bar, control arms. No problems till I rolled it (did I mention I am a genius on dirt roads)?:mad:

I assumed that the parts he had are the ones he listed and nothing else significant. When he lowered one end of the drag link with a drop pitman arm, he took them out of parallel.
