Common questions
What thread does this use?
It is a 12x1.5 thread. Confirm it against the nuts currently on your wheels or the GM fitments in the description above so both diameter and pitch line up.
Does the seat need to match my wheels?
Yes. Conical, ball, and mag seats do not swap freely, so the seat on this nut needs to match what your wheels use. Your existing OEM hardware is the simplest thing to compare against.
