quick question need help asap
 

just bought the rough country 3inch lift and it comes with lower control arms, and sway-bar drop brackets. is that really needed??

No.But,you can always install later if you really want to,though.

No, but it'd be worth to at least change your control arms, the rc ones are beefier and are longer than stock so they'll make up for the lift. Plus it'll be a pain to do it down the road when you wished you did it all at once. As for the brackets I'd just ditch them and get disconnects
