Track bar over axle. Possibly lowering the frame side to match drag link. High steer, or OTK drag link with a drop pitman arm. Suspension links should be as flat as possible also.
Here's mine at ride height


Oh and just because it came from the factory doesn't mean in any way its the best desing. Best for the cost maybe, but not tje best.
You're saying your rig handles better in it's current state over stock?

It its lifted, and the steering ends mount to the same points how would the geometry be the same?
if the drag link and trackbar are parallel to the ground, you can get a naturally floaty feeling on center, and possibly some bumpsteer. a very slight angle is best, or so, thats what i've read and have been told.

also, you should keep your drag link and trackbar as close to equal length as possible. most important is keeping them parallel to each other.

This is absolutely true. People often overlook the length thing too. When they are 2 different lengths, even if they are at the same angle to begin with, the arc radius is different and will travel different lengths through suspension travel. You will also loose some turning radius because of it. Being parallel to the ground is not though. Although the design of the joint changes this a little. actualy the flatter the drag link and more parallel to the tie rod the more "direct" it steers it.

Im not saying my jeep "handles" better than stock. But it certainly steers better. Im pretty sure that having no sway bars, and 37" tall bias ply tires contribute to it not handling to well.
I posted that picture to show my steering angles, and how my links are almost flat. It is incredibly resposive and tight. Also the toe doesnt change through out travel like an inverted Y. Which makes my steering better than factory.
My point is just because the factory put it on there, doesnt mean that there could never be anything better. Everyone always argues the point that if there was something better it would have come that way, and that is just simply not the truth.

Its funny too because when I was really into road racing it was liek the most important thing to keep the track bar and steering parallel to the ground, that was the like one golden rule in balanced suspension. Its so funny coming to off road stuff from that and looking at how truely horrible most steering really is.

I'm confused as to what kinda track cars have steering and a track bar on the same axle actually.

Let me rephase this theres no perfect steering set up on lifted vechicles as taking your steering set up and swapping to my xj or visa versa mine feels perfect to me

Measure the angles of a stock setup, play with high steer options until your in the ballpark.
I'm going to do the wj knuckle conversion and ill only be at 4.5" i believe it will be better than stock.

Thanks for all that I didn't know some of those things but that gives me a lot of new information. I definitely need to rethink my track bar a lot I never knew lengths made that much of a difference.
