2015 Sierra Z71. RC 2" Level and Dominator D2 steps. Will be going with some larger rubber when the stock ones wear a little more lol. Came from a 2014 2500 Cummins. As much as I miss my diesel I must say I'm very happy with this truck so far! My wife and I were Mopar people cause our salesman was AMAZING! I had 2 Rams and she drove a Dodge. But than our salesman moved to a GM dealership. Long story short I needed to get rid of my hefty Cummins payment in order to get our mortgage. After all the dust settled after buying our house we followed our favorite salesman and bought the Sierra and a Terrain for my wife. So far...we're quite happy with our switch
