i am running 31s right now on what i think is stock size. i have small blocks on my back axle where the leaf is , and im not 100% sure it's a lift, but im pretty sure it is. I want to run 33s on my truck, and if i put 2 inch leveling coils in the front would that work with no rubbing? or would i also need a 3 inch body kit ? any help would be great
