Hey everyone! so i am going to be ordering the Rancho here in a few days when i get back up to my FOB, and i was wondering if you guys suggested i get a 1.5" spacer to go ontop of the Rancho or should i have no rubbing at all with the 35" km2s? i know i could do a 1.5" spacer and 37's as guys over on f150online have done it with success, but i JUST bought the KM2s so they are going to stay for a while lol.

Zach, i dont remember you having any rubbing issues with the Grapplers, so i doubt i will have any problems with the KM2s, just wanted to make sure!!!!
