Okay so here's my story. 2006 nbs, 6 inch pro comp lift, but no aal in rear so it sits cali. I'm not a huge fan of cali so I want to fix it.
A zero rate aal would be perfect but got a 4 inch block already, and not really feeling like "stacking". The front is exactly one inch taller and I don't want to decrank because I'm not maxxed out and like the front PERFECTLY. A regular aal would lift too much then I might max out my t-bars trying to match the back again. Is a 5 inch block to big to run, or would it be okay? I know the rear springs are kinda squishy on these trucks, but the ride and drive is just about perfect now with the bilstein 5100s. (P.S. Thanks for the advice on those, GREAT decision for anybody looking to buy them!)

I had your same problem. NBS w/ 6'' pro comp. I did a shackle flip with the stock shackles and a custom 2.5'' zero rate. I'm pretty level now. I do have Ford keys though
