I called Summit Racing and the sales rep on the phone wanted to know the stud size and the thread pitch. I told him the make, year, model of the 4Runner and he said he their computer won't tell him the size. I went to Family Toyota last night and the guy at the parts desk told me the same thing. He even suggested I buy a thread pitch gauge.


Sounds like you need to find new dealers...

Since I don't know what you drive, I will assume Toyota 4x4...which uses uses M12-1.5 on all of the six-lug vehicles.
