I am on very steep inclines and it will lean a lot with it off. It does ride smoother, but does lean a lot more if you aren't going evenly up or down something.
Yeah I noticed this,side slope can be a little uncomfortable. I actually had the left front tire come up off the ground, crossing a fairly steep side slope and turned left to go up hill and saw the left front tire lift..same place with the swaybar it had never lifted like that.
Also I like to hotdog(as much as a 4 will hot dog:rofl3

on the flat trails from time to time and the body roll is pretty bad at speed..same curves with and without the swaybar I have to slow down alot more without the bar..
It does make the rough stuff a little smoother,which is great...but I think I will hook mine back up for now...
