In response to your comment about tire sizes, I have an 03 GMC Yukon XL and it fits 285/75R16 on the factory 16" wheels without any additional lift. Sorry I don't have any pictures of it without a trailer handy.
Any new updates?
I have a 2003 Yukon XL 3/4ton 6.0L that we take out. current mods are 285/75/16 BFGs, K&N Intake and I have a Hypertech programmer for it at the shop but haven't installed it.
