I just completed a triagulated 4 link SAS on a 95 GMC using a hp d60 out of a 88 f-350. I had a buddy convince me that I needed a panhard bar, which I wasn't sure I needed due to the triangulation of the links. Now, my axle will not go to full droop on the passenger side due to the panhard. I'm thinkin I'm going to forgo the panhard and just run it without because I don't like to think that I'm binding on my passenger side lower link due to the fact that the panhard bar is trying to pull the axle towards the drivers side at full droop. Other than this issue everything is working perf. Any comments, opinions, or words of wisdom are welcome. The truck has about 7" of lift over stock, and I have not had it out yet. It is using 14" king coil overs, but all of my articulation experiments have been done without the shocks installed so as not to limit the viewing of the articulation to check for binding issues. sorry to write a novel, just wanted to add any relevent info.

You don't need a panhard bar with a double triangulated setup.

congrats on completing the linking, is your panhard close to flat when the truck is sitting flat, or on an angle?

I'm not an expert by any means, but I remember reading that if your links were at a 30 degree or greater angle the panhard in not required.

A panhard with a triangulated 4 link will surely cause binding.
Pics?

the panhard is at the same angle as the drag link

if you are running a triangulated 4 link in the front, you cannot run a panhard. It will bind. All your links are trying to move the axle straight up and down, and the panhard is fighting them and trying to push it side to side as it travels up and down. Your buddy is smoking crack, lose the panhard. Now that I think about it, you may want to redo the whole thing. You are going to have massive bumpsteer with the triangulated links. You either are going to need full hydraulic steering, or a staight 4 link with panhard. Basically start over.

Well first off a true triangulated four link does not need a panard rod. Second: double triangulated four link will have a ton off bump steer when using mechanical steering. So ditch the panard and throw on some full hydro and you will be styling

Yeah, I KNEW I didn't need a panhard but listened when I should have done what I knew was right. That's why you triangulate your links. oh well.

Listen to this guy ..... your buddy is a moron....

Basically start over.



Yup! Or go full hydro.
