I swapped to PB 1" Forward lowers for my dually. I noted the same concern as you after building some pocketed stock arms for it. There was >.500" clearance around the bag @ 30+ psi when I validated dimensions during their build phase. But once the weight of the all iron BBC & those chunky hubs were resting on things the bags (Firestones) had less than a yardstick clearance sitting still. That would yield a failure in the field @ some point so I ordered a pair of PB's arms & never looked back.

I wound up removing some RideTech arms (from the 1st batch they ever made) and getting PB's narrowed arms for my 64 as well. I wanted to pull the track width in a little more & his quality/customer service has always been excellent.
