Firstly, thanks to all for posting your rides and going through all of the ins and outs of your lifts, fitments, etc. Lots of good looking vehicles on this board that led to the update of our new Yukon. Again thanks.
Secondly, to show my appreciation and to provide you all with some additional information to help those in the future, please see the pics of our completed lift and tire update. I'll post pictures of the front fender liner / tire clearance after alignment. It is close and may rub through suspension travel but nothing that I can see so far during normal commuting, bear in mine we only have put 40 miles since install/alignment
2023 Yukon SLT 4wd (coil suspension)
2" Rough Country spacer lift
285/65R20 Mickey Thompson Baja Boss ATs
Stock 20" aluminum wheels (no spacers)
Full size matching spare
Full size spare fits but can't see getting anything larger in there without deflating the tire a bit. FWIW.
