Does anyone know if a stock front bumper for a 2016 Sierra 1500 would fit on a 2014? I replaced my stock one and am trying to sell it so it's not taking up any room.

Looking for a little help here. I got myself a 2016 Sierra 1500 a while back I finally have the time to start lifting the ol' girl. I was looking at a rough country 3.5" suspension lift. However they also have kits that include the upper control arm or the knuckles. How would i know which is the best fit for my truck? Do I realistically need the kits with the control arm or knuckles?
