I'm telling you guys, 4/7 with 275/55/20s on stockers will work on NNBS trucks. The only issue some have is minor rubbing on fender liner at full lock. NNBS trucks have a lot more room up front than NBS trucks do, a 275/55/20 on an NBS truck at 4/7 will rub a lot.
Here is another one for you, I can do this all day long:


To the OP, the issue I would be worried about more would be bottoming out in the rear if you aren't doing a C-notch, which I'm guessing you aren't. Did you order helper bags? If not, I'd suggest doing them when you install your drop.
