Noob here. Just collected all the necessary parts and scheduled the lift for next week. After reading a few dozen posts I think I only have one question: Are the wheel spacers necessary? I don't want my footprint to be too narrow so I'm thinking yes?? 2012 SR5 4X4, OME 3" suspension lift, ProComp 7036, and Duratrac 285 70/17. Any advice would help. Thanks!!
