Check my suspension geometry

I want to make sure it is set up right. 4" fabtech lift, RC adjustable track bar, drop arm on steering, 33x12.50 tires, 1.5" wheel spacers.

Everyone always argues whether the drop arm is needed or not, but otherwise things look fine.

There is no 'argument' or gray area about the drop pitman arm. The nice thing about math is that it doesn't lie. Put the stock pitman arm back on and your steering geometry will be correct. Why vendors continue to include them is beyond me. Jeeps haven't had leaf springs since 1995. As for your suspension geometry, that's a whole different subject with a whole different set of variables that I doubt you care to get into. Given that you posted a picture from the front, I would assume you meant to say steering geometry.

And I don't know what kind of track bar that is but it's a bit on the scary side. Make sure your bump stops are set correctly, as you wouldn't want that thin TRE shank to be the bottom-out point.

Well beyond the drop pitman arm, Fabtech lift and RC track bar its ok I suppose, not a fan of wheel spacers myself....
Violence may not be the answer but it sure cuts down on the stupid questions

It's obvious the dropped Pitman arm should not be there, get rid of it and install the non-dropped OE Pitman arm. The reason being that the upper end of the track bar is still mounted to the OE (non-dropped) track bar mount. The Pitman arm and upper track bar mount must match.... they must both be dropped or they must both be undropped. When they don't match, when one is dropped and the other is not dropped, as you have, bump steer is the result. On a Wrangler TJ that is.
When you have a choice, buy American.

I see a drop pitman arm, which needs to be replaced with a stock pitman arm.
No bumpstop extensions, so the shocks are bottoming out.
The track bar looks like it will hit the diff cover without proper bumpstop extensions.
The brake lines appear stock, which are too short for your lift/extended shock length.
The stock steering stabilizer needs to go, they suck. Replace with beefier aftermarket of your choice.
I can't see the lower control arms well, but I hope they don't have poly bushings because those are known for ripping control arm mounts off.
The tie-rod is stock and should be upgraded for 33s.
The anti-sway bar brackets are a bit odd, I'm not a fan.
