The answer is YES, it sure does. I was amazed when i was burning up the curves with both HD swaybars with a RTT up top. Your driving style almost becomes Hooligan worthy.l
Not sure how much of it you are joking but yes it does make a good bit of difference, not quite as big as rear sway bar upgrade but still very noticeable, I am not scared when I have to make a sharp turn anymore.
VERY happy that I upgraded both sway bars, now if only I can get off my lazy a$$ and install the delta bracket.
