I think that would only apply if the link was mounted below parallel, monted higher would result in more body roll due to less twist in the torsion bar. At least on paper.

 

Don't you all just love these technical discussions that mean absolutly nothing in the real world.

 

I think either higher or lower would have similar effects.

At a true parallel and with up/down travel forces is applied at a 90 degree perpendicularity the forces are transmitted torsionally into the bar the most efficient. As the bar becomes less parallel the links act at less than 90 degrees so some losses come into play as some energy is put into stretching compressing the link.

Again, it would have to be pretty far off center for this to be detectable and at that point I think you might have link or link mount failure.

 

 

It would have to do with the direction of the arcs the axle and sway bar are traveling in. A lifted jeep would have axle moving forward when stuffed and reward when drooped, the same as a sway bar that is mounted above level. If the sway bar was mounted below the level point it would travel in an arc that moves reward when stuffed and forward when drooped causing more of an angle in the link to sway bar location.

 

Hahaha. I drove for months without a rear sway bar and never noticed it wasn't there. I'm really glad we talked this one out

 

I'm enjoying the discussion because it helps me learn. Thanks, guys.

Wouldn't the links being longer have an effect when the suspension reaches it's mechanical limits? It seems to me that if the sway bar is 10* raised for example, when one wheel reaches full bump it would have less torsional (rotational) force being applied to the opposite wheel since it hasn't twisted as much as it would have from level. And therefore at full droop on one side it would have more rotational sprung force than it would have if the bar was level.

Just trying to learn stuff.

 

If you're getting 10" of travel you are disconnected and the sway bar is no longer a factor.

Edit to add... yes when the relationship or angle between the arm portion of the bar and the link itself becomes less than 45 degrees this becomes a factor. I highly doubt anyone running a traditional 4-link type suspension is traveling enough for this to be a factor though. (especially upward travel.)

 

I disconnect at the mall.

 

I had to read this a few times, but I'm pretty sure I agree.
