i just got my 90 4runner with a 3.0 up and running. it has 5.29's(detroit rear/open front), 4in. lift(trailmaster) with a 3in. body lift. its going to be my daily driver. i also have an 85 that i currently have 37's on. i was thinking of pulling the 37's off my 85 so i can get 39's for it and have 37's for the 4runner . i'm planning on a sas for it in the near future, but want to make sure that in the mean time i don't dump a bunch of money into the ifs becasue the 37's will be breaking idler arms and what not. its not going to be going on any trails until the sas done. what do you guys think, will ifs on the road hold up to 37's for a few months?
