Yes, or lateral control arm if you are at the parts counter looking for a new bolt for the axle mount and the guy looks at you like you are retarded for making up words such as trackbar or panhard rod. And people wonder why I hate parts guys so much. That reminds me I need to call Cdan.
hmmmmm...that's kinda sweet looking. Actually, if you have a tube bender, a welder a couple of bushings, a few bolts, that doesn't look too un-doable. Just thinking out loud here. But with this setup you would never have to keep adjusting the rods, or mounts no matter what lift you are running.
The issue with the LR setup is that your tires move closer to the body as you lift the suspension higher. So, pick your poison - move the axles forward into the body or move the axles sideways!
Ali, you sure about the moving closer? I know if you lift alot they move closer but it has nothing to do with the A-arm, it has to do with the lower control arms as they pivot down the tire is naturally pulled closer to the body. I guess in a sense that is affected by the A-arm since the pivot point is where the lower control arm hits the axle, so tilting hte axle back would gain a bit more room for the tires. Also Rovers have a dropdown bracket for the balljoint in that A-arm which moves the balljoint to the back more and down some...as you know.
I admit having a off-the-shelf A-arm item to just bolt in would be a bit iffy, alot of liability in that I would think since you are totally changing the suspension, not in a stupid way, but still modifying it heavily, not just with a lift but new engineering.
On lifts for jxxps they handle this by putting a bracket on the axle housing to raise that point, so the trackbar is level again (or close) but not by lowering the frame end, but rather lifting the axle end. In either case there is alot of force to deal with and fairly high stresses there which only increase as you get further from the original mounting point, thus giving the trackbar a lever advantage on whatever braket you come up with, definetly something you'd want to be careful with.
I was looking for a picture of the 4Runner drop-down bracket to post here, but haven't found one yet...

The pic of the 80 that Phil posted has Man-A-Fre's prototype lift kit; I think it's a 4". Talking with one of the guys there, it sounds like the kit consists of dropdown brackets like for an IFS lift. Personally, I and most I'm sure know that Slee kit/s are the best out there!

*moving to the back of the class till I have a lightbulb moment*
Still don't get it ...
Not sure what I'm looking at in that animation of the 4 link . I understand that as the suspension is lifted in the 2nd photo , the axle will shift leftward , but thats about it ...

Ty,
The issue is the angle of the panhard. See how the top of that piecce in the animated picture move sideways and the bottom does not move as much?
If the panhard is at an agle, then when he axle moves away from the body, the pnahard "pulls" the axle to one side. If you have a panhard that is totally horizontal, then when you move the axle away from the body (say 10") then the pull will be much less than if say the panhard is at 45 degrees.
When you do your suspension this weekend it will all become clear. Now go break in those Carhartts.

Here is a good pic of a 3 link set that works well with 28" of travel
Phil, so in that pic, there is basically no need for a rod? Since the axle is centered with the two side bars, and the one hunk in the middle.

Phil ,
How does that V-shaped pc move up/down ? I can see how it would keep the axle centred and allow droop on either side , but I can't see any joints where it meeds the tube frame that would allow the frame end to pivot ... essesntially allowing straight-down movement .

T Y, if you look real close, it's mounted to joints on the frame, just hard to see because of the gussets right in front of it. So it does have up-down movement, just not side to side.

Ok , thanx .. that makes sense , of course 
Now what about these side bars ?
Seems to me that if the right side droops , for instance , that that tire will follow the radius of the right side bar .. thereby travelling down and slightly back towards us (in the pic ) . Does this mean the other side will try and stuff up and away from us ?
IOW's upon droop , will the axle also try and rotate slightly ?

Here is what the pivot point looks like (360 degrees of movement) it’s the same front and rear. Zero side to side movement.
This is how it attached to the rear end. The links also piviot 360 degrees.
