I'm am very new to the 4x4 community and my Colorado is actually my first vehicle Ive owned. That being said please forgive me for knowing so little. I have many questions regarding a body lift for my 2012 Z71 rado. The first being does this void warranty? I'm looking towards a 3" lift assuming that this is the biggest available without affecting crucial components. Does anyone know of any easy to install kits for a 2012? Also what size tires would you reckon I could fit without rubbing? If anyone could break this down barney style for me it would be much appreciated, Thanks - Dillon
