Shipping was quick and it was packaged very well but had multiple imperfections including a dent big enough that the paint chipped on the grille. The damage definitely happened before shipping because the way and the location of the marks it couldn't have been during shipping without a clear indication on the packaging. All the parts were there, the instructions aren't the best but the steelcraft bumper install on YouTube covers everything nicely. Overall it fits nice and looks good, I could've sent it back for the damage but didn't have the time to wait for a replacement. 4stars because of the damage and it didn't come with even one sticker
