Idk if this is allowed, if it isn't, my bad. I'm looking for info on lowering my Denali AWD. Only thing is that I have a Yukon...I know they drivetrain is similar so I figured I'd ask. Also I saw you posted the picture of the Yukon so I figured you'd know about these. Mine is an 08 Yukon lx, I'm looking to do a 4/5 drop. Is that safe? I know vibration might be an issue after going past a certain amount so I'm looking to do this right. What parts do you think I need or is this a crazy idea?
