Air bags for rear suspension

I do wish FS stated why they need 1/2" clearance. I would have liked mine higher up. I used the Daystar cradles too, and yeah, they're thicker than the FS base, so the air bags engage even sooner. I guess it's all a compromise. For the weight I carry, I need them, so I'll take the +s with the -s.

 

Yeah, i couldn’t figure out why the instructions say to leave 1/2”. I quadrupled checked the bag clearances to any part of the frame or the frame’s bumpstop bracket and there’s not going to be any rubber rubbing against anything. That’s the only reason i can figure why firestone would say that.

 

As others have said. 5psi when unloaded.

 

Maybe hardware clearance inside the frame rail?

 

Possibly. Long story short, i welded my brackets in place so hardware clearance wasn’t an issue i looked at.
