Yeah I've been noticing that. I guess that is why guys run bed cages to compensate for that. It raises the upper mount to regain the otherwise lost uptravel.
I went out today and measured the shock length when the truck sits normally and found the eye to eye distance to be 20.5". I then measured the bumpstop to the stop on the block (by the way, the block is a 2" block) to be about 4.125". Oh and the bumpstop itself is about 2.125" tall.
I first thought the compressed length would be 20.5-4.125=16.375, but then realized the shocks are mounted at an angle and not straight up and down so this calculation is not applicable. So it seems I will have to get some flex to measure it at compression to know for sure, aside from trying to apply some trig. But I think the geometries and the swing of the axle makes it a bit complex. Besides, getting the actual measurement under full compression would be certain to give me the correct compression length.
