They are just a round piece of aluminum 1.5" thick with 6 holes for your studs to go in then between each of your studs is another set of studs for your wheels to bolt onto. They willl make your wheels stick out farther. I'll get a pic up today.
Also maybe somebody can help.... These came off my new chev, according to google they will also fit a titan but I dont want to sell them to anybody if they dont fit. So if anybody knew for sure they didnt let me know. Any measurements anybody wants I can get to help.
