best panhard bar location ???

so i'm going to install a parallel ladder bar and coil over set up my 33 pickup and i was wondering the best panhard bar location, i never understood the diagonal location, isnt the panhard supposed to stop the side to side movement, so wouldnt parallel with the rear end be best?

 

gonna have a kinda high " roll center " with that bar up in the sky

might be best to ask a knowledgeable stock car builder on placement

 

Watts linkage is way better than Panhard for lateral location of a coil sprung live axle....

 

i know the watts is better but my kit already came with a panhard so i miight as well use it

 

The triangulated bar is NOT a Panhard Bar - By definition a Panhard bar goes parallel with the rear end.
Some pretty big name chassis builders will flat our tell you that the triangulated bar should NOT be used on the street - Drag Cars ONLY
As for Panhard, parallel to the rear end in both planes is best and the longer the better. Lower is better as well without getting into too much technical stuff.

 

DO NOT put the Panhard bar below the axle. Can you say Bicycle.

 

parrallel to the rearend at ride height is best

 

Go with the set up in your first picture. That is actually called a "diagonal link". I run it and I run it on the street as well as the track.

 

i just dont see how the "diagonal link" stops the side movement on the rear end anywhere near as good as a panhard bar would??? ive never driven a car with a diagonal link

 

A diagonal link is a race only setup usually used with a four link rear bar. You do not want one with ladder bars.

That isn't a street friendly suspension, imagine going from the highway turning into a parking lot where one rear tire at a time has to go up over a slight curb - it won't be able to do it with that suspension. You'll hear squeaking and squrawking as that suspension goes thru a bind.
Don't need a panhard bar with that either, unless you do away with the diagonal link.

 

Well that is the same suspension I run on the street. Many miles per year without a problem. If you notice, there are spherical rod ends on every mounting point. That makes a difference. No, I'm not going to be a "cone killer" with this suspension but who on the H.A.M.B. is building one of those anyway?

 

Using Weasels drawing of a panhard bar you should visualize that the bars up and down movement will pull the axle housing towards the frame mount. In your application the bar should be level , as long as possible and parraell the axle housing or slightly lower to minimize this motion. Most beleive the frame mount should be on the passenger side.
