Does anyone that has traction bars installed feel like they have a sway bar type effect.
no. not in the slightest.
what they do make possible is way less axle wrap. The truck will rotate a lot quicker and it wont lean as much, but only because if you keep your foot in it, it'll slide instead.
they make rotating the truck a ton more predictable, which it uses could make you think that they have a sway bar-esque effect.
My tires get stupid sticky when they are warm, so on pavement it is a bit more effort to get my truck to slide, therefore the traction bars almost have the opposite effect (when compared to swaybars) on my truck, on high traction surfaces.
the truck sticks and I end up with gangsta lean/ 3 wheel motion if I take a turn on pavement a little too fast.
