Pannard Bars?

[1929]

Anyone using Pannard Bars, front or rear? I saw them in one of the vendors parts book. Any benefits with having them?

Our 79 Volvo had a substantial rear panhard bar, but it had a lot more torque and hp than a stock Model A. I do not see the need for one on a stock Model A.

They work by hiding suspension problems.

They were on the town sedan I purchased, and it's not clear how much was added to stability on turns, etc. However new modern style tube shocks, if one uses them, can conflict with the front sway bar.

I have both stock Model A's and also Hot Rods with Ford based suspension.

I do not have Pannard bars on my stock Model A's as I do not think I would gain much from them,

However, I do have them on my Hot Rods. and they really help, especially, if you are using cross steering or have longer than stock spring shackles.

Please note, Pannard bars and sway bars are two different things. Pannard bars are used to eliminate any side to side movement of the axle relative to the center line of the vehicle. This results in more positive steering. Sway bars are used to reduce the amount of "lean" of the vehicle during a turn. They can also be used to change the understeer or oversteer characteristics of the vehicle.

I installed both front and rear Pannard Bars on my 31 Slant Sedan and there is a difference which is noticeable on a windy day, the car feels so much more controllable.

The bars keep the springs from "Swinging" in the shackles which keeps the rear centered. The front Pannard Bar may not do very much because the Pannard mounting bracket has flex and this negates the functionally of the bar, the rear bracket is a very heavily made structurally and will not flex.

But again there is a definite difference because I experimented and disconnected both, drove the car with them disconnected and on turns it was quite a noticeable difference without the bars attached.

A panhard bar does not hide suspension problems.

A panhard bar prevents the sideways movement of the suspension system allowing the car to ride better and be stable under hard cornering.

This system must be set up in a neutral position, horizontal at ride height.

I use one because I have coil overs . keeps the rear end centered

Panhard Bars keep the ends of the axles from moving back and forth. The Model "A" has radius rods that do the exact same thing. Why do you need Panhard Bars?

[bettlesr]

The radius rods don't really keep it from going sideways. The radius rods keep it from going back to front and twisting up and down.
And yes, the front brackets are too flimsy to do much good.

What is your problem with your model A? Then maybe we could help you with your problem! If you would goggle panhard bars you'll find what they are used for and not get all kinds of answers.

[pooch]

Radius rods do nothing but triangulate the outer diff housing for strength .

The diff is still free to swing sideways on its shackles in cornering with or without radius rods.

A panhard bar locates the diff from this sideways movement.

No problems, just curious.

Do a search, I am sure that there was a similar thread about 6 weeks back.
That may also be worth a read...

The radius rods keep your camber angle, the springs being transverse are mounted using shackles and the rear end assembly and front end assembly can actually swing back & forth on the shackles, panard bars do work and are very noticeable on a windy day. It is a inexpensive fix for better handeling and will not harm the car,s suspension. I personally drive the wheels off my slant sedan and my car is much more controllable in windy conditions or when I take a corner at any moderate speed.

If you have a suspension problem panard bars are of ZERO help! they are only used when a person is looking for a better handling car, no more no less

I just this last weekend installed a rear Panhard bar to my '31 roadster. I can't say I noticed an improvement when turning corners, but maybe I am too timid in cornering. I do feel I noticed improved stability in freeway driving (60-65 mph), with the car having more firm 'yaw' control.

The stock Model A chassis doesn't use pannard or panhard bars as the front suspension users the wishbone, transverse spring and shocks to control forward, upward and lateral suspension travel. At the rear it uses the torque tube, transverse spring and the shocks to control forward, upward and lateral suspension travel.
At the front if you split the wishbone or use a modern 4-bar or hairpin set up hi will need a panhard bar for lateral suspension control. At the rear if you use a modern axle and separate prop shaft and coil-over shocks and ladder bars or a 4-bar set up and DON'T use a triangulated 4-bar set up you will need a panhard bar or watts linkage to control lateral suspension travel.
A triangulated 4-bar setup does not need the pan hard bar as it controls all degrees of suspension motion without it.
Really sorry if I have just confused matters!

Here's my contribution to the thread that Fiftyv8 linked above. It's my story and I'm sticking to it:


I'm not sure if we're answering the question, but I agree with Purdy and Richard. I have AC&R's Panhard bars on both front and back of my Town Sedan. The rear one made the most difference and it was VERY helpful. The sideways swinging on the shackles is dampened and the whole car just feels more solid, less loosey-goosey. My guess is that they don't help nearly as much with lighter models, like roadsters.
