maybe better explaination of my thought:
in order of contact from droop to compression:
shock shaft bump
upgraded bump in factory location
fully crushed shaft bump
fully crushed factory location bump stop
~1/2" to shock bottomed
~1/4" to beam crashed to bare frame
should I reverse the last two so if all bump stops fail, the beam crashes the frame before the shock fully bottoms? Laying it out like that, I think you're right. Frame should crash with ~1/8" of shock left. With stops in place, probably wasting about the top inch of shock travel but hopefully won't ever hurt the most expensive part of the truck
