Meh... I ripped that thing out. I have done this in the past on several pick ups/ 4 runners without anything noticable happening. Maybe aa bit of body roll was the only thing on the heavier pigs... will report back after it gets off the jack stands it has been living on for a week.
Test drive later today!
EDIT: Took the Van for a 50 mile jaunt without the swayy bar. Really didn't even notice it was gone, probably because only one side was connected for who knows how long? Ha... Just getting going on this thing and am finding all kinds of things interesting, and irritating. Typical I am sure...
Anyways. Final report: Kind of an unnecessary piece of equipment imo. Feels like a normal ride considiering other things I have driven.
