I´ve got IFS so then there´s no need for further plans. I wanted the center differential cause with the solid transfercase it will go almost straight forward in tight corners when snowy or icey roads. I was gonna use the HI-Lock mode and disengage my font axles for normal 2wd driving, but i did some research and found out that the case will take damage with the center diff locked for longer time so it wouldn´t have been a good idea anyway. Thanx for the replies any way! And by the way, there wasn´t ever a thougt about changing the 3 spd.
