Hey guys, I'm looking for dimensions on rb25 headstuds. Looking to see if I can custom fit them in my project(non-rb)

I need overall length, how long the threaded portions on both ends are, and outside diameter of the included washers. Pics would be great also.

Only thing I know about them is that they are 11mm in diam.

Thanks in advance!

Have you measured what you need? Arp can make or find the stud you need. That's what I did to get rb25 studs before they came in a retail package. I don't remember the dimensions though.

My current studs have an overall length of 4.6in and are threaded 1in on each end.

I'm really looking for an off the shelf kit that I can make work for my motor. Plus the ARP kit for rb20/25 is pretty cheap.

I may look into sr20det studs as those are 12mm in diameter I believe.

Well the sr studs are too long. Those are out.

Anybody have a set they can check real quick?

Or rb26 studs?
