    Hi All! Hope everyones doing well. Ok, I'm going to throw this out there and see what happens. I have been building up a Model A chassis for a rod that can take me on extended road trips. Here's the non traditional part. I am using the transverse rear spring because I like the looks.I am using a Ford 9" rear differential, yes, mounted the hangers on top. So, the rear radius arms were of no use being i started with an enclosed shaft banjo rear end. I decided to go with ladder bars. Because,,I like the looks."muscle". Ok,,my question for all is. If, I am using the transverse spring and my ladder bars are not parallel with the frame. Not radically but triangulated,, Do I need to worry about lateral play? "panhard bar"?

    Thank you all in advance. :;)

    Pan hard bar would be a good idea.

    I've read that a panhard bar isn't needed, when going with a transverse spring. But considering how easy they are to build or purchase, why not?

    I had a 27 T rpu with ladder bars and a transverse spring on an 8" ford. The ladder bars did follow the frame rails though. This had no panhard bar and worked great. Now I have a 31 A tudor, it also has ladder bars but is sprung by coil overs on a 9" and it has to have a panhard bar. The T with the transverse felt better than the A with the coilovers and panhard.

    It depends on the angle of your shackles, If they hang at 45 degree you want need a sway bar, But if they hang stright down you will get side sway. I had to put one on a 31 roadster I just built, It wanted to rub the tires on the body on a hard turn.

  6. What makes your build non traditional?

    Sounds similar to the frame we built for my truck. HRP

  7. The spring mounted on top of the axle will make it sit higher in the rear. HRP

    Wouldn't a Watts linkage work better?

    With a panhard bar you get some side to side movement with suspension travel. That's why the watts link I would use rubber bushing in the ladder bars with a panhard..

    Hey HotRodPrimer can you tell me some specs on that rear end set up? Is it Pete & Jakes 32 kit for the ladder bars?
