Dominator Air Bag Rubbing Issues with PB Extreme Dropmember

[Jayschevy]

I have a front Extreme Dropmember on my 71 with Dominator 2600 bags that came with the kit. The upper part of the bag seems to touch the frame when it has less than 80 psi of air in it, but is fine when it has over 80 psi of air in it.
Just wondering if anyone else has had this issue and if there is a way to resolve it without buying new slam bags which are 1" less in diameter? I would like to ride low without worrying about rubbing a hole in my air bags.
Thanks
