Up for sale is a new set of 4 McGuard wheel lock lug nuts with key. These are listed for use on Corvettes with steel wheels or rallye wheels. Not aluminum wheels. They will fit other Chevys with the same stud threads. The part number is 17511, so check your application. I have had these sitting on my shelf for a long time and the packaging show it. This was never opened and the last two pictures are from another set I am selling, so you can see what they look like. These are brand new and never installed. Please contact me with any questions. Thank you.
