Panhard Bar

[Ike]

Looking for ideas for building panhard bar. I have a transverse spring mounted on a 36 Ford frame. This is the rear spring that I've attached 36 radius rods.
I'm a homebuilt builder so homemade is always welcome. If you have any pics. that would help. All help appreciated.

This is a coil over rear with radius rods but the panhard bar would be the same.

With a transverse spring do you really need one,i would think the
spring would hold everything in alinement.
Panhards keep things from moving side to side.

You are correct. A panhard bar is not necessary in a transverse leaf application...

Long Shackles

I have long shackles and there is some movement. Even if you have short shackles there is movement. The spring moving up and down and the shackles pivoting allows the rear end to move. A panhard bar installed correctly elimanates any side movement. Thanks DMW56 for the pics of a well done piece of work.

I'd suggest you find some other way of lowering the car.......those long shackles never were the right way to do it. The sway you are finding is one reason, and they change the relationship of the spring to the perch too. People did this sort of thing back when there weren't many alternatives, but now there are so many better ways to do things.

As mentioned, once you get rid of them you won't need a panhard.

It kinda depends on what body style you have. if you've ever riden in a '40 Ford tudor with 4 people in it, you know how much lean there is without a sway bar. Ford used them in the '40's to control body lean. Even with stock shackles, with that much weight above the rear axle the body will tend to shift the body/frame causing the shackles to go horizontal on one side and vertical on the other. If you're building a car, it's not a bad idea. If you're building a truck and don't plan on hauling much more than a cooler and acoupl of lawn chairs, then maybe not.

Old Cars Have Sway

The springs under an old Ford have sway. I am trying to elimanate that body sway. Even short shackles have lateral movement. They are nothing more than hinges on the end of a spring. Youngster was correct when he spoke about body sway. All the old Ford had body sway. I guess it depends on how much movement you will tolerate. I do not want that sway so that's why I ask for panhard pictures. I build safe cars and trucks for my family to ride in. I replace or rebuild any parts that looks questionable. I have been accused of over building. I have built many bikes and rats and nothing has ever broke. Thanks for your opinion but I'm still looking for panhard ideas.

Here's my experience: It is a pretty different setup but the theory is the same. My Anglia has a parallel 4 link with coilovers and a panhard bar. A must with a parallel 4 link. It rolled enough that the tires rubbed the inner fender panels in back when cornering. I know, what's an Anglia doing going around corners? I had to add an anti-roll bar to eliminate the problem. The panhard bar will keep the chassis located relative to the rear axle and will restrict side to side motion but won't prevent the roll you might be trying to eliminate.

May be a Watts link is what you're looking for?
