My 2016 Sierra after level and tires. Went with the Bilstein 5100s (1.85" level), and 275/60r20 Goodyear Wrangler Trailrunner ATs, stock SLT Premium Plus wheels.
Love the setup so far, ride is 10 times better, absolutely zero rubbing, no noticeable MPG loss (these trailrunners are the same weight as the stock tires). I think it looks perfect, it gives the truck a real "OEM+" look.
