Many here seem to misunderstand what a "sway bar" actually does.
In simple theory (aka physical reality) it reduces body roll ("sway" is a misnomer)
It does this by resisting the two sides moving independently
Now another part of theory (again, physical reality) is that making the suspension
stiffer reduces the road holding while cornering.
But there's another factor, body roll can change suspension geometry on INDEPENDENT suspensions (not a factor with solid axles, front or rear)
And on Independent systems this can prevent undesireable effects which
again reduce traction.
Let me remind everyone that "engineering" at it's root is chosing what
compromises to live with.
But a LACK of body roll can inspire more driver confidence
(atleast in a vehicle with which the driver isn't intimately familiar with)
On a solid axle truck (BOTH axles) particularly a raised one the body roll
can distort one's perception of what the vehicle is doing, say during a collision avoidance lane change manuever, and this can really get you into more trouble than you're already in...
Sway bars aren't complicated, but some of what they do is counter intuative.
Build your truck the way you like it.
I've got the stiffest sway bars I can get on my 1.5" lifted 4x4
but I'm still running TTB ad as I've said many times before my
primary use of 4x4 is AVOIDING going offroad.
But my definition of "a road" can be somewhat loose in it's interpretation.
There are generally a dozen or so days a year where I need 4x4 to get up the hill (on the paved road) to simply SEE my drive much less get into it... or worse, out of it.
so my truck is primarily a "run to the junkyard" and "drive from pennsylvania to wyoming" machine.
