Awesome truck! Thank you for the response. All these makes me nervous haha. I hate that you get different answers when you talk to different companies or people. Dirt King, Fox and Camburg All said I’ll be fine. Method recommended 0 offset with a 4.75 back spacing to fit the 35x12.50x17 on my Silverado. With that said the wheel wells are different from the Silverado to Sierra. So I’m keeping my fingers crossed for a smooth install.
