I’m sure you would know this if you rethought about it real quick, but the addition of a body lift would not change the need for the 1” of bump stop. Shock travel (fully compressed here) is not affected by the presence of a body lift.Oh and a 1" bumpstop will be fine. If you haven't already and you add a 1.25" body lift you shouldn't need any bumpstop.
However, if your tires require 2” of bump stop to keep everything clear, the addition of a 1” BL can drop the bump stop down to 1”.
UKTJ, from what I can tell you’re on the right track.
