the top mounting point doesn't have a hex insert in the middle of the shaft? that's pretty poor planning unless they want you to ruin your shocks as you tighten it down lol. as for your lock rings loosening up, try putting some loctite on the threads where you want it and see if that holds.
I'm not sure how the inverted shocks look, but is there a hex on the bottom of the shock? maybe you have to hold it there and tighten the top
