Jade, I haven't had any rubbing issues. I just bought my truck used and the previous owner did the FLM install so I can'ttell you how he set it up or if he had any problems with that initially.

As far as shocks, I am looking into getting the Big-Bores right now. Is it correct that the rear takes the XX Long Big bores and the front uses the Long Big bores? Also would like to know whats the best springs and oil weights to use with an FLM setup. Looks like MaxxFusion has big bores (I think) Maybe he can chime on with some thoughts...
