To the best of my knowledge all of the aftermarket wheels are a copy of the Chevy ralley wheels. They come with either the ralley slots, artillery style, or smoothies. I have the smoothies on my truck and they look stock except for the depth. You can get them in a variety of widths and bolt patterns. The difference from stock wheels is that they are made to fit the ralley style hub caps. You can have the stock caps modified to fit these wheels. They remove the mounting ring and weld in a smaller ring to fit the new style wheels.
