do you all think the cst 7" lift is a pretty good kit? I have an 08 Pro-4x that I'm looking to put it on. and how difficult would it be to install? I have helped install a 4" lift on a 4runner so i know some and my dad used to sell Snap-On tools so we have plenty of tools lying around just didnt know if it would be too much harder than a 4" lift
