I have a GMC Dually 06 and have used these nuts on aftermarket wheels. Before buying I wasn't sure what the front wheels looked like due to their length, but now that I have them on I really like them! They look great, the quality seems very high and the Lug Key has a good fit. Definitely recommend. I've included a few photos because I couldn't find any photos of what they looked like in aftermarket dual rims.
