Sway Bar for Rear
Well, curiosity got the better of me. I bought a $40 sway bar off Amazon and fit it into the rear of the Model A. It is snowing so I don't know how it drives yet. I got the Dorman Porducts # 927-159 which is for the back of a Crown Vic if I remember right. It is pretty narrow and smaller diameter for a softer touch.

Re: Sway Bar for Rear
We have a nomenclature failure here.
That is an anti-roll bar, not a sway bar. A sway bar can properly be called a track bar also depending on how it is adjusted. |

Re: Sway Bar for Rear
Thanks GeneBob for the information!!! I have one coming 11-6, when you get out let us know how it works.
Pete the anti-roll bar is one item that has been called way to many things !

Re: Sway Bar for Rear
OK. I went for a drive around the big block and I added some intentional hard gas leaving the turns. I have to say it made quite a difference. The rear did not drag the car around the turn and the rear tires actually did some side drift (just a tiny bit).
My biggest concern is the u-bolts around the rear axle. I don't know if they have a good grip on the axle tube. I am thinking of adding a feature to make sure they don't start to rotate back and forth depending on the direction of turning. I went with the lightest duty bar I could find because the car does not weigh very much and I didn't want to over-cure the "sway". For a quick and easy build, I think it is pretty close. |

Re: Sway Bar for Rear
I don't think I'd corner hard enough to appreciate the improvement.

Re: Sway Bar for Rear
Does the rubber "bushing" press tightly against the axle housing?

Re: Sway Bar for Rear
Katy, I put the U-bolt metal bridge in between the rubber bushing and the axle housing. Are you suggesting that the rubber would provide enough friction if I let the bushing contact directly against the housing? Another interesting suggestion from the clever collection of connoisseurs at the Barn! I though the rubber would be too hard but it might work. Thanks!

Re: Sway Bar for Rear
Maybe try a paint pen to draw a line cross the axle tube and a fixed point to easily see if there is any movement and in what direction.

Re: Sway Bar for Rear
Smokedtires, another good idea. Thanks.
BTW, I just picked up a couple 3" exhaust clamps to swap out with the u-bolts that I had on there. |

A track (or panhard) bar is a straight bar that goes from the frame to the axle the help keep it centered in the chassis. A Watts link works best for this but they can be complicated and expensive. https://www.newmarcorp.com/blog/what...a-sway-bar-do/ https://www.motortrend.com/how-to/tr...-4x4-vehicles/ https://www.americanmuscle.com/what-...atts-link.html |

They function when turning in both directions. A track bar's only purpose is to transfer weight in a circle track race car. They are adjustable and in some cases by the driver while racing. |

Re: Sway Bar for Rear
I’am planning on using a muffler clamp on the axle housing, rubber gas line around the U- bolts and flat rubber strips under the tie bar for a temporary install. When everything is tested and working, the clamp tie bar or manufacture a new heavier mount will be welded to the axle housing. That’s my plan for now when the anti-roll bar arrives Thursday

Re: Sway Bar for Rear
Big_hammer, I was wishing I could weld a small flat piece onto the bottom of the axle tube but I don't have the capability. The rubber pieces should protect your axle tube but be aware of the substantial taper of those axle tubes.
I will be trying to install my 3" exhaust clamps later today. I might try to put a taper into the clamp bridge to match the axle tube. |

Re: Sway Bar for Rear
OK. I changed to the 3" exhaust clamps and I think this is as good as it gets. General ride is, I think, a little better because the uneven road causes less side to side rocking motion. Going around corners is definitely better; less roll, better feel without being too much, too rough.
Not bad for $40 sway bar plus $17 for the strap (that will be used on future projects as well), and $12 for exhaust clamps. A couple holes drilled, a little spray paint and it is done. Last edited by GeneBob; 11-01-2023 at 06:06 PM. Reason: Add pictures |

Sounds good ! Thanks for your post and findings! Mine arrives tomorrow and I’ll be installing mine this weekend.

Re: Sway Bar for Rear
Did the exhaust clamp come with the saddle part? if it did you might consider sandwich it between the rubber part and axle housing...

Re: Sway Bar for Rear
Big Hammer,
Note: I could not use the rubber bushing clamps that came with the kit. I used the 1 1/4" X 1/8" strap from Home Depot to make new clamps with hole spacing that matched up to the width of the U-bolt on the exhaust clamp. Oh, and I made the height of the replacement clamps just a little short so they would compress the rubber bushings by maybe 1/8" when tightened down. Last edited by GeneBob; 11-02-2023 at 10:07 AM.
