Stupid Swaybar ?
 

This may be a dumb question, but can I run a swaybar backwards, as in the endlinks facing the rear? I ask b/c without making my own swaybar (I dunno if I'm up for that or not) I won't be able to use one as it will interfere with the lower bar of the 4 link. I don't fully understand how a sway bar works, i know that it controls body roll but don't know really how. So not sure if turning the thing around would work or not. I see alot of people making one to fit there app, this would be ideal, but I don't really know what all that entails or where to get parts from either. Not running one is not an option since it's a truck it will already be so prone to body roll it's almost dangerous. So, once again, sorry about the newb questions, just still learning.

Yes, you can run it with the arms going backwards. The final goal is to connect the rearend housing to the frame with a"flexible" torsion bar that will still allow some give when turning. I've seen swaybars mounted on both the frame or the rearend housing with articulating links connecting to the opposite.
There have been engineers who have developed mathematical models for determining the exact diameter, length, and geometry for such things. Those models are great, but I typically play with a few different combinations until the vehicle is fast and comfortable. At that point I dont care so much what the math says.

Thanks man, it seemed like I could in my mind, I just wanted to make sure it worked that way. As far as the math involved in "perfect" suspension geometry, you can get close but I think the final tweaks come down to the driver and who they want the car to feel.
