Ok, I found a problem with your math. You used Pythagorean's theorem incorrectly. You should have done sqrt(24^2-15^1) instead of sqrt(24^2+15^1). This is because 24 is the hypotenuse and 15 and your unknown are the sides of the right triangle. This will give you 18.7. Subtract it from 24 and you get 5.3" of change in the horizontal direction.

If I understand your placement of the heims (pin is vertical), then the rotation of the center link does not matter for heim angles. You already found the angle between the outer and inner links at atan(15/24)=32deg.

Iím actually putting one like this on a customerís rig; itís made to bolt to the dynatrac axle. Itís a 07 JK, dana60ís, 6.1 SRT Hemi,42Ē goodyear Kevlar

OK, which angle do you need?

It looks good but seems like it adds a lot of complexity for what it does.

No, the real problem is that there are no right triangle and you're using 2d math to try to solve a 3d problem.

I see an awesome application on air ride equipped vehicles where you can slam it for road cruising and then lift it for play time.

That would depend on how the panhard is mounted and where. If it is only as wide as your frame then yes, it will move a lot more. And you're also talking straight down travel of 14". In the rocks thats really doesn't happen. It's one end or the other flexing down. Thats what I was talking about that there is very little movement if built right, not the whole axle dropping out like if it was airborne.

I get that you're wanting to use your smarts but do you think you're the only one to think of a watts on an offroader? If it was worth doing it would already be being done with a lot more consistancy.

And again, what does it matter if your axle shifts a bit when flexed out? It's not like your going fast when that happens and it's not enough to bother anything else.

Awsome, awsome, awsome. That's what I'm doing. thanks for the pic. I knew someone has done something like this. Thanks for posting it. To all the haters out there remember JFK "We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard" Keep you panhards, But I going with a Watt's

What's the rest of your setup going to be? Radius arms, links with heims, links with johnny joints, leaf springs, coils, coilovers, air shocks? And I asked once before but didn't notice an answer, what's your intended use?
