Rear Shock Choice for 2015 TRD Off Road DCSB with Steel Bumpers

I am about to install Pelfreybilt front and rear bumpers and understand I need to beef up my suspension. At first was looking at 5100s but learned I need to run stronger coils. I was looking at OME 886 coils and 90000 Nitrochargers in front. I was thinking of going OME shocks in the rear with an add a leaf but hit a snag, as I am hearing the OME is problematic for install on the rear.

Do you have any suggestions that wont break the bank and will still be safe ride?

 

I have OME on back. Had to grind the mount a little though so shock would clear it. Not a drastic amount if you're willing to do it.

Edit: Dakar leaf pack does really well under loads.
