Yes. ^^^Many have said that. In off road conditions (2WD or 4WD) you want your truck to kind of bend and move with the rough terrain. The sway bar restricts that.
Around town it HAS TO BE the best $200 mod going.
And "yes" a sway bar is heavy. Yes, it is difficult to get it into position, hold it there, and get two bolts in. You need to block up the sway bar. Raise it off the ground. The shipping box can get you really close (set sway bar on top of box). I did it with stacks of 2x6 and 1x4 pieces of wood (this method allows you to incrementally raise it a piece of wood at a time). If your girl has stout big tits tell her to lay under your Tundra for a few minutes.
