Parts & Accessories Spare parts Sierra 2013 fully repainted for cleanliness. It has a 6.2 engine, Denali transmission, Bilstein shocks, full headers, and a Weiand intake. The engine was recently rebuilt, only four months ago, and it has a warranty. The vehicle is, by the grace of God, a ready beast, lacking nothing. In short, I have invested a lot of money in this vehicle and it has cost me a lot. Please do not lowball.
