shit i didn't even know they made the trucks with a sway bar that mounted to the radius arms. must be real early chassis like what we are talking about. all i've seen are mounted to the front of the ibeam.
with 4 valves in front, you shoudn't need one, but if you only have 2 for the front (both bags on the same air "circuit") the air compressed out of one spring will transfer to the other and dip the truck real good.
