'11 Sierra w/ noticeable lean to the right

[badfnz]

My 2011 Sierra has a noticeable lean towards the passenger side. The difference in fender gap between the front driver and front passenger is only 1/2", but that's enough to tell when looking at the truck from the front or back. Last week when I measured, the fronts were the same but the back right had an entire inch less compared to the back left. Not sure what's going on here. I have a RC leveling kit and 1.25" BL. I've looked under the truck and don't see anything out of the ordinary. Any help?

Was your fuel tank full?

Did your truck look this was before the lift?

I had this with an older truck. It was a broken sway bar link. Check the bushings, too.

I've had the lift for almost 4 years now but this lean has only been present for the past few months. It's not fuel dependent.
