It can be done, buts not as easy as it used to be. I have a 3" on my 09 and it took almost 2 days to install (I am very fussy).
Parts included in the kit may get the job done, but I found it better to cut and weld the intercooler pipe for a better fit. Radiator drop brackets needed to be modded, as well as some other small changes from the instructions.
I have never had a safety concern with any body lift I have installed for myself or others...
