I've got a 1" BL, the 1.6" Ironman kit, and 1" wheel spacers all around now. 33x12.5's on stock rims. Low profile bump stops on the up travel, no bump stops on the down travel (it travels more than a stock setup would).
Was out Labor Day weekend at Sherman Peak, and had ~1000 lbs of gear in the truck. Suspension was tapped out on several obstacles. With the exception of some previous body damage making a piece of plastic stick out on the front left (caught the mud flap and tore it off months ago...it would occasionally catch on where the flap used to be, since it became convex when it tore off...) - there was not any rubbing anywhere. We did a quick trailside repair to the offending section (took 5 mins) before starting up the trail and all was well.
