I have a 2002 F150 FX4. I ordered a set of front and rear rotors for my truck from NAPA and they said that my rotors will have 12mm stud holes. I was reading on here today that my truck actually has 14mm studs. Will the 12mm rotors be interchangeable with the 14mm rotors? I read a post taht stated the 12mm studs actually have a ring at the base of them that is 14mm? Is this correct or will they not fit? Has anyone else had this problem?
Thanks for all the help.

 

I HAVEN'T HAD THIS PROBLEM BUT 12MM STUDS ARE SMALLER THAN 14'S, SO EVEN IF THEY DID CHANGE OUT MY THOUGHT IS YOU WOULD HAVE TO CHANGE TO LUG NUTS THAT FIT 14MM STUDS

 

I have been looking at pads and rotors for my 2001. Every part store that I contacted had a listing for both 12mm and 14mm studs for the rotors. I ended up finding on the face of the rotor a stamp that stated 14 mm in between the stud holes. I woould suggest taking off one of your tires and check to see if there is a stamped number on the rotor. As previously mentioned, 12mm is smaller than 14mm and I do not know if there is a ring or not. Maybe someone else will chime in with other info.

Good luck
