Swapping a body lift to a long travel suspension lift

Very new to this, i put in a 6” RC body lift (worst thing i could of done) and was thinking about swapping it with a suspension lift (king 2.5 w reservoir) and rear king 2.5 shocks, would i need to get after market control arms? Do i need to add a bump stop? instead of smaller lift blocks do i need leaf springs? also will i need to relocate brake lines? really set on king shocks but just don’t know the things i have to do to fit them in correctly. thanks!

 

i was looking at the wrong coilovers, just the king 2.5, not the long travel spec, i also was watching yt vids before i posted on here, some people were lowing their diff so that’s why i said that. like i said i’m new to all of this haha. but i guess it’s a drop bracket lift, has strut spacers and 4” rear blocks.
