I went to my local speedshop on Sunday after failing tech Saturday night(front = Draglites, spacer, 12x1.5mmx2.5" ARP wheel studs) looking for the long GM studs or to maybe going with 1/2" or 5/8" studs. No luck on the GMs but the guy had a new ARP catalog that showed a new 3.25" wheel stud from ARP.
I searched ARP’s website and Googled but couldn't find any info on them. I called ARP and they verified them:

Part number: 100-7713
Knurl dia: 0.509"
Knurl length: 0.315"
Overall length: 3.25" (no nose - threaded to the end)
Thread pitch: 12x1.5mm

Kind of pricey: $20.63/set from Summit (5 in a set)

Summit has them on their website but doesn't list any info about them (what they fit, dimensions, etc). They also show them as on backorder. ARP says they have them in stock. I ordered on Monday and have a “tentative” delivery date of 5/13/05.

Uhhhh, Lingenfelter has been selling them for about 3-4 years. I have an unused set if you want them. PM me if so.

I thought the Lingenfelter's were only about 2-5/8" long. These are about the same as the 2.5" long ARPs I have now. Close if I grind my calipers and dump the spacers but not sure if they'd still be long enough.

Just measured them. 3 1/4" from the lip (what butts up to the hub) to the tip of the studs. Last 1/4" is not threaded though.
