they're only saturn because they probably had a request to make them for saturn first and found they could cross reference to KA somehow. they didnt make ARP KA studs until 2002 or 2003 i think.

not that it matters, but that's how it works many times. if a KA person had come around first, it would be vice versa and saturn people would be asking for KA studs lol.

either way they work and work well.


ps - the 11mm ones aren't saturn based
