I have 4 brand new American Racing polished forged sidewinder wheels for sale. I paid $1800 for these last fall. These wheels are lighter and stronger than cast wheels. I went with 18inch Weld Method wheels on my truck. They have never had a tire mounted on them. The shop I bought them from would only return them if I paid a restock fee. I would rather see if someone else wants them. the spec are: 17X8 with 4.5 inches of backspace or 0 offset. the bolt pattern is 6-5.5. These are the larger center bore but they would work on all 6-5.5 GMs also. Each wheel comes with a closed end center cap.
