there's nothing wrong w/ them, they work very good. i noticed maybe a 50% less sway when i installed mine. there is only one problem: the peice that you connect w/ the top of the suspension is not that strong and will conform to the bend when you screw the bolts in, but it doesnt break. the actualy sway bar is steal and doesnt bend at all. these are adjustable and are very good money savers.
i got mine from power garage, they have alot of parts for suspension and intake systems. but, hey dont have the rear lower roll bar which is what i wanted.
