Oh ok. As I said a couple days ago, I'm prepping for the move to 37's also. Since The majority of my wheeling is low speed, my plan is to lower bumpstops as needed and gain back some down travel with the Dobinson 4" "flexi" progressive coils and their 6" lift shocks. 4" of up travel should be sufficient for my needs. Who knows, I may end up with more than that without major fender surgery. Minor fender alterations are not out of the question at this point though.
I took measurements before I removed the stock suspension. Toyota dialed in 3" up and 6" down, basically, in the front and rear was similar. 6" up is not necessary unless you will be sprinting your pig across the desert.
