I need advise on the steering geometry of my lifted JK. The F/T 3" ultimate with HD springs produce this much of a difference in spacing between the drag link at the Pitman arm end.
At the steering knuckle end the spacing is 1 1/4". At the Pitman arm end it's more than 7". Although the ride is like driving a "deuce and a half" truck, the bump steer, darting, wander, etc. seems OK. Front tire pressure is 30 psi/rear 28 psi. The caster is set to +8 1/4 degrees drive side and +8 1/2 degrees curb side and the handling, like i mentioned, is decent. The ride is lousy. Is this a situation where a dropped Pitman arm or high steer drag link might improve the ride characteristics? Any guidance everyone can provide will be GREATLY appreciated.

Really? 8°+ of caster with a new steering dampener and you're still having handling issues? Have you tried adjusting your toe to being closer to 1/8" in? That might do the trick for you.

No, not really handling complaints & absolutely no ESP issues either. Just a very rough ride. How does one adjust the toe (it does have a slight pull to the right)?
Here is WOL's alignment write-up. He explains how to adjust toe in it.
