You want 6” This is a better option with coil overs.

rough country has poor metal coating and shocks. Changing shocks will improve the ride: fox, king, bilstein, ome, ads, icon.
I agree with you. I was just writing why control arms are good. Yes if the coil overs are extended travel, uca are needed.
If crash bars are modified and OP did some trimming they could put a bigger tire.
Depends what you paid.
Depends on if you want an f-150. I like the size but don’t want to pay the higher registration and I have a narrow and short parking stall.
IMO go with a company that’s guaranteed for life. I’ve had to deal with my wife’s car, the tint started rippling and the installer replaced for free. On a previous truck it also started peeling. But I didn’t care, traded it in for a ranger.
