I'd suggest you make sure you look into Hub-Centric rims for any GMC/Chev wheel changes. On my 09 Duramax, I went to an aftermarket aluminum rim and chased bad high speed vibrations for years. I went as far as adding hub-centric rings to help center the newer wheels, balanced them 6 ways to Sunday, and still had issues until I finally put the old wheels back on when I sold that truck.

I now have a 2015 GMC 2500 series. I have installed aftermarket wheels and a mild lift on this one but made sure the wheel I chose this time around was Hub-Centric in design. I still get a small vibration between 60-65mph but typically drive through that each time as I normally drive at 70mph plus on the highways. Ask the tire and wheel tech about that at a GM dealership. These are the guys that see all the problems that pop up with wheel changes between truck and wheel manufacturers. There are ones to stay away from.
