Anyone know the specs on the stock wheel studs? Any vendors sell extended ARP studs?

Thanks!

do FC's and FD's use the same studs?

Thanks,

I'm not sure if they use the same studs, but be aware that the shorter 2.5" long ones have about the same useful length when installed in the rear as the 3.25" ones do when installed in the front (on an FC). I'd expect the FD to be similiar in this regard.

Hmmm how odd. I tried those studs in my GSL-SE and they were too loose. Just bumping them with my wheel would knock them out. I couldn't find a proper long stud that was press in style. So, I ended up putting helicoils in my hubs, cutting off the knurl and screwing them in my hub with Locktite.

Well there's the fundamental difference there, FC's and FD's have press in studs to begin with, FB's don't.

I think the stock knurl diameter is 0.506", so these are slightly bigger for a good snug fit.

Oops... my bad. I bought the 100-7711 which has a .485 knurl. Ha! I wish this thread was started a year ago when I was searching high and low for long studs.
But anyhow, the GSL-SE is a press in stud. All other 1st gen are screw in studs. The SE and the 2nd gen both take the same press in stud when browsing for replacement parts. The Dorman stock replacement stud is a 12.90 mm (0.508 inch) knurl so indeed the part you are recommending is slightly larger for a nice tight fit... perfect for those NASCAR style 13 second pit stops...

That makes a lot more sense. I thought it was rather odd that you'd try to press in studs into a threaded hole.

^+1.

I run the same setup. I also had the shorter ones in the front, but with the wheel spacers I'm running I needed more useable thread. No visible thread outside of the lugnut is not a good idea!

Black91n/a

Me too, at first I had 2.5" all around, then to better accomodate my track wheels and the spacers that they need I went to the 3.25" ones.

I know this is an old thread but, is it the same for front and rear on an FC?>

The new wheels I bought cant be fitted without extended studs and I need to know if the above part number will give me more useable thread in the rear?

Also, can I also use the same part number in the front to get a little more thread? Thanks!

Front use 3.25
Rear use 2.5

These will equal similar available thread lengths.

If you are looking them up, use C5 Corvette as a base line then pick your length. They use the same knurl and stud size/thread as the FC.

Keep it simple. Use these all around, that way you don't need two different spares. The 3.5 are just fine on the back.

Part Number: ARP-100-7713
Wheel Stud Style: Press-in
Thread Size: 12mm x 1.50 RH
Knurl Diameter: 0.509 in.
Underhead Length (in): 3.250 in.
Knurl Length (in): 0.315 in.
Overall Length (in): 3.500 in.

MrGoodnight

iTrader: (1)

What about if im looking for 2 inch longer in front, would i be ordering C5 corvetter studs at 4.5 inches?

RockLobster

Yup, basically you buy the ones for late model vettes and camaros.

Doing my front wheel studs right now. Same part number as above. ARP 100-7713. Still gotta do the rears whenever the budget allows.

Sorry to resurrect an old thread but I've been searching and haven't found a definitive answer. What is the underhead length of a stock wheel stud and what is the overall length? Thanks a ton.

I'll try to get a picture, by tonight, of FD, FC, and ARP studs all side by side with a ruler for comparison. FD studs are a bit under 2 inches if I remember correctly. I stock ARP extended studs for FC and FD on my website www.j-auto.net. I also carry stock replacement studs if needed.

Finally had time to take a picture of the OEM studs next to ARP's extended studs. Hope this helps everyone



Wheel studs can be purchased from my website www.j-auto.net

How did you get the extended ARP studs in on the rear hubs!? FC1987

I was thinking about filing out a slide-in spot so I can angle the studs in and just rotate to put the rest in.

** I found the answer.
