Hey guys, new to this forum and am full of questions. My current ride is an 2009 Chevy Tahoe Z71 2wd. I have a few things that I have done to it, removed the plastic shroud around the nerf bars, and changed out the stock 6 cd changer for an pioneer head unit. Current tires being used are 285/65R18 nitto terra grapplers on stock Z71 rims. I believe it is leveled but not quite sure since I don't know what the stock measurement from center of wheel to bottom of fender. Once I get those numbers I will be happy. My plans for it is to put a Superlift 6" lift with fuel trophy 18x9 wheels with +1 offset and 305/60R18 cooper Stt tires. Could someone help me get the stock ride height of the Z71? All advice will be greatly appreciated.
