Additions or complete change question?

I have a question for those suspension gurus out there. Trying to see what my options are to add about three more inches to my 3/1 lift that’s currently on my truck. I have Pro comp UCA’s, fox 2.5 Coilovers with reservoir and Fox 2.0 w/ AAL in the rear. Would prefer not to have to change the whole thing and if anything how would a BMC affect it if I did that also? It is my DD and mostly used on pavement and have done/ will do occasional off-road trips. Thanks in advance for those willing to chime in and no need to answer with smart remarks please. Trying to learn here so please refrain Thanks!!

 

No adding 3" without chop chop, cut cut drop bracket unless you are 2wd - then a spindle can be used.

 

It’s 4wheel drive so I can’t do spindle lift. Is 3” body lift possible? How would that affect anything if it did/could? Also with the current set I have now, would I be able to let’s say get a kit from like BDS without the Coilovers and rear shocks since I already have those? I Would also choose coach builder shackles instead of blocks.
