No I don’t think there is much there to be gained in my set up. The shock is only so long. Rancho 999255 have 9.84” of travel. So I should be ok with 4” up and 5.5” down. I don’t know enough about where travel should be to worry about changing it. Is haveing 5.5” up and 4” down worth cutting all 4 control arms down? My guess is if it was I would have noticed. I do make some high speed runs up through Mendocino, but haven’t noticed any severe bottoming out do to not enough up travel. My spring unseats by about 1.5” now so moving the shock mount up 1” should make for a pretty well balanced spring to shock travel. Looking to do something similar to what your planning on the shock tower.
How much bump extension is needed to keep those Currie coils from binding?
What have you been able to do on the rear as far as shock fitment?
