Someone at PSC needs to learn a few things about rockers.
This whole sandwiching between the body mount and tub is a crap design. Those three mounts under the doors sit in dimples on the underside of the tub. Those three mounts are designed to be compressed a specific amount to carry the weight of the tub. How do you expect that to happen if you compress 2 of them a half inch more than the one in the front because you span over the dimple instead of up into it?
Would anyone here in their right mind shave a half inch off of two body lift pucks on each side under the doors and call that correct?
How about if I send the guys with no body lift 4 half inch thick pucks and have them install them under the doors on the last 2 mounts on each side? Would that be okay?
Further, look at the rear slot on the rail. See that little finger of metal pointing to the inside? Guess what happens to it when the over compression of that body mount gets done with it?
There is ample room to make that finger another inch wider so that it won't distort up into the dimple in the body.
While I haven't installed a set or really looked at the mounting system up close I think I understand what you're saying.
So if they were going to use this style of mounting system properly, the way to do it would be to insert the rocker guard in between the frame mount and the top body mount so that the top body mount still sandwiched in the concave in the body, correct? So the order would be body > body mount > rocker guard > body lift (if used) > frame. This would work better assuming you have a flat body lift puck and not a contoured one like Currie makes.
The only potential problem I could see here is that this may create a gap between the rocker guard and the body...
I suppose another potential fix would be to include a new shorter body mount which goes under the rocker guard and fills in the concave in the body properly. If you chop 1/2" off your body lift puck and insert it in between the rocker guard and the body does that fill in the concave properly? The best solution would be to provide a new shorter body mount here that installs above the rocker guard yet does not create a gap between the rocker guard and the body.
Looking through their website it appears they have changed their mounting system to what I described above for the Unlimited:
