does anyone know the standard sierra front wheel stud length?

i'm trying to order some approx 10mm longer than standard, but can't easily measure mine at the moment.


Thanks in advance.

I think Rally design list them in sizes + standard.
I have a bag of standard ones. I will measure when I get home if no one else has the answer.

standard length of 12x1.5 is 47mm not including the head.

I have just removed the original studs from the front of my car and replaced them with Ford originals, why? because some were damaged and i thought i would replace each wheel set.
The original 1982 studs are 35mm from shoulder to end, the new Ford ones were 47mm and Rally design advertise 47mm studs as 13mm longer than standard!
they also do 63mm studs.

I fitted the 47mm studs and had no problem fitting the wheels and nuts, i now get 13 to 14 full turns
The original short studs were probably for steel wheels.
I did also notice that the unthreaded shoulder of the 47mm stud was also longer and protruded through the hub face further
