5.5" of lift questions!

[Destructo]

I'm going to assume I will need a transfer drop kit for this much lift (need it for 6" anyway) also will shocks that come with a 4" lift kit work for the extra 1.5"? And will the brake lines work with the brackets included with the 4" lift?

The method i'm choosing for this amount of lift is a 4" rough country All spring lift, with hydro shocks, raised steering arm, brake line extensions (may upgrade to SS lines in the future). For the extra 1.5" on top of the 4" lift I will be running 1.5" heavy duty daystar front shackles and 1.5" lift blocks in the rear. I will be running 35x12.5" tires also.

So what will I need on top of the stuff that a normal 4" kit comes with? Transfer case drop, and where can I get one? I'm getting the 4" rough country kit from JCwhitney (cheap shipping) which comes with rear blocks but I bought a brand new pair of rough country rear 52" 4" lift springs off ebay which will go in place of the blocks. Will I need to lengthen either of my drive shafts?
