Bilstein 5100 at 2.5" (top setting) and Snugtop Shell...OME Dakar 2.75?

I installed Bilstein 5100's on my truck last year and recently moved the front coil over strut clip to the top setting (2.5" I think). I need to level out my rear and was thinking of installing the OME Dakar 2.75" leafs. I have a snug-top cab which I understand weighs 250lbs.

OME offers the medium and heavy duty spring package which I believe is for a constant 200+ bed load. Anyone have any experience with a situation like this or any suggestions?

FYI, I'm ordering upper control arms too, suggestions on them would be awesome as well.

 

I just got an add a leaf from ready lift. 67-7120 and it did a good job. You need new shocks when you raise the back end. I got 5100. Also maxed out my 5100 on stock coils on the front.
