I'm in the process to level out my stock 2014 Gmc short bed z71 4x4 what's my best route to take and what would I need to make it best i can?

What size tire you running and wheel

I have a 2014 Sierra z71 single cab short bed. Any recommendations on a leveling kit and some tires that will clear on stock 18s? And also would I have to change out any parts while I'm doing the leveling kit to avoid future problems. The truck is currently all stock . Any help? Please and thank you
