I installed these nuts on my truck almost a month ago and even used a mounting adapter to specially mount them with a Tourqe wrench instead of an impact wrench as per the instructions recommended. . I have a set of $4000 LTZ wheels but unfortunately these nuts have already shown horrible signs of paint chipping and rusting! I'm glad I'm preparing to take these wheels off for the season as the rusty nuts make an expensive wheelset look awful, not to mention they are more difficult and risky to take off, put on and ride.
