points A and B don't change from each other, which means they stay lined up. the difference is the extremety of the angles at which they operate, which is where DPA and trac-bar drops come into effect. dpa and tb drops are necessary only to maintain good operating angles on the tie rod ends and to keep the track bar from binding on the coil spring bucket at flex....they do (in conjunction) keep the tb and drag-link parallel, but you CANNOT do one without the other, and it's personal preference on whethere or not they need it...my experience doesn't justify it at roughly 7" of lift, so I won't advise someone to do it at 3.5" of lift...that's just silly given my experience. it's not high enough.

I think we were disagreeing over nothing and just mis-interpreting each other's statements/maybe I missed where you said track-bar drop bracket too. you can't do one without the other

I probably wouldn't at 3.5, I would just use an adjustable trac bar in the same location, angles wouldn't be severe, unless it caused problems, at 4.5 I disagree and think the angles would be severe enough to justify it. I'm actually shocked it hasn't caused you problems at 6.5, but if you don't take it on the road much, you might not notice it. Hit a bump at 45 and see what happens. Shepwood is building a DD, not an off road mostly Jeep, thus the need to make sure handling is up to par.

it's my d/d right now since I'm mid-restore (again) on my 86 camanche with 96 camaro motor, and the company van died and they havne't replaced it yet.

actually, it's been my only running/driving vehicle since july 2008...I built it in about 2.5 weeks of working on it whenever I wasn't at one of my 3 jobs lol.

but yeah...no issues at all. I take it about an hour each way every day to work when I'm not out of state for work. also run all my errands/parts run and have regular interstate travel at 65+mph. have no issues really except that I have the old style of RC control arms (threaded center, solid poly bushings, they pivot on the threads) and the upper arms are getting loose.

I would call that damn lucky then. But OK, I still say no 2 are the same and you might run into problems with the next at 4.5, might not. I've had them 3, I've had them 11.5 (very custom and way to much money to justify ever doing it again), they have all acted different. My DD gets bump steer at 3 right now, not bad but noticeable, last 2 didn't. Go figure.

*shrug* in all the jeeps I've had, or my brother's had, we've never had an issue with bump-steer all the way up to 6.5" and there's about 7 lifted jeeps in there...some bought that way but most of them we built. I don't think it's luck, it's a general response thing, proving to me that while yes, they are different..they're not THAT different.
