Front bumpstop size a full compression?
Does anyone know the size OEM front bumpstop compresses down to at full compression? I have a TF 4" lift that adds upper and lower extensions and looking at my shocks, I know I can reduce the size of the extensions to increase upwards articulation. just want to try to get my math right and figure in the OEM's length when compressed.

theres a video where teraflex discussed the advantages of speed bumps and they do a demonstration where the stock bumpstops compress to a point where they are no longer visible in the press. I believe it can be seen in the full length prerunner video.

i just installed TF Lift 4" and I found to much bumpstops as well. so the front I took out the lower bumpstop since it was almost touching at rest. I actually have 3" of shock shaft and 3" between bumpstop to bumpstop (not including factory off white bumpstop) so everything is good. I ran 6" lift shocks.... not sure if it was worth it yet.... I have more tweaking to do... I degres.... now the rear I need to change the bumpstop as well. I have 2.5" from bumpstop to bumpstop and I am not sure how much shaft is showing right now. it could be 3 or 4" but that shock is on an angle so that distance could be even more depending on movement. I would expect more up travel is needed to compress shock all the way due to its angle. I have yet to play wtih that.
Wouldn't swapping to the 6" shock - vs the 4" limit your up travel by about two inches? (Though you do get the down travel increase?)
I need to do some double checking, but I have about 2.75" shock left at full compression (assuming OEM bumpstop is 0" at compression). That TF upper extension is looks like 2.75" showing. The lower bumpstop looks like 2.5". Think I'll remove the lower.
