2023 GMC Sierra 1500 AT4 — need advice: Lift is installed — what geometry needs to be rechecked?

Write down what you already tried. A second data point from another 2023 GMC Sierra 1500 owner helps more than a generic diagnosis. That's where I'd start. Just my two cents from doing this recently. I'd sleep better after that step, even if it finds nothing. This is the version I'd tell a friend.

Don't overfit one forum story to your car. If it still isn't clear on the 2023 GMC Sierra 1500, a specialist hour can be cheaper than another round of parts. Then you'll know the next fork. Parts cannon is a personality type I try to avoid. If the story changes I'll post the new data.

Owner notes beat generic advice here. On the 2023 GMC Sierra 1500 in Raleigh, I'd fix the thing you'll notice every day before chasing spec-sheet extras. I'd do that before spending real money. On “need advice: lift is installed — what,” that was the fork that mattered for me. Parts cannon is a personality type I try to avoid. That's my plan before I call anyone.
