Longer wheel studs needed. What's stock size?

For the wheels I have I need longer wheel studs in the back to get the lugnuts to screw on to more threads. I don't however know what the stock length is to know what size I need to get. I need about a half inch longer to be on the safe side. Please someone help me out. Thanks, Zach

I want to say that the stock length is somewhere around 1.5", but I could be wrong.

Try them out. It looks like 1.5" is stock size, and they sell 1" and 1 3/4" longer ones, based on what their site says.

Hmmm...Seems like I saw those but I don't know why I didn't read that part about length. I bet those would work though. Thanks, Zach

Yes the ARP 7708's are longer then the stock studs.

stock is 2" but the threads only go 1 1/2"

I found Dorman studs at Car Quest #610-323

M12-1.5X54mm serrated bolt

they worked very well for my front runners and 5/16 spacer

I ordered the ARP studs from Thunder so hopefully they will work. Thanks for the quick help guys. Makes it where I don't have to wait.
