I even tried finding a Dorman equivalent stud with no luck. My understanding is you either drop down to the 1/2" and save some cash or stick with M14 and break the bank. I'm in the market for extended studs and feel your pain.

So, per this link:
1/2" extended studs for $165 for all 20 w/ lug nuts
M14 extended studs for $240 for all 20 w/ lug nuts

Less than $15 for 4 studs. Or around $60 for 20.

And then take ten grind them down so they fit in the back. Ours are more because we include more.

Here is a solution if you have need spacers as well as studs.

H&R hub wheel spacer kit include the correct length M14 studs with the notch cut into the head and ready to install. You can buy the studs from them as well but the wheel spacer kits are a good value if you need the spacers.

15mm and 17mm kits include 10 studs in the kit. You can find the kits for about $115.00 shipped.

Unless they have new studs then the ones they list on their website they would need to be welded in. The knurl is smaller than the Ford part by about .040". We know because this picture is what happened.

That said if they actually have a stud with the correct knurl diameter in 14mm for $4-5 a stud that would be great for the street guys. I would verify the studs they have in that kit before you buy.

That does not look good, I have another set that are not installed, what is the measurement for the correct knurl and I will measure the ones I have to verify.

the ones I have in their current kit are:

knurl size - .625" or 15.875mm

I do not have a stock one handy to measure.

Dave, The .625" would be correct, did you measure the ones yourself or is that what they say they are. We would like to know, they do not list anything on their website that resembles a .625 knurl diameter. If they have a product that works that would be great.

Asking this question here as some of you posters may have removed the stock studs ... how much space is in the back of the hub before the splines on the stud no longer seat on the splines in the hub?

In other words, if you were to tap the stud as if you're removing it, how many mm's approximately would it need to be tapped before you could easily wiggle the stud?

I ask because it's either tap the stud back into the hub 3 mm or trim my studs 3 mm to fit a spacer size I'm considering. I'd think a tap of the stud for only 3 mm would be safe but just asking.

Thanks!

If I'm reading this right you want to unseat them 3mm? That's a recipe for a mess. Once tightened they will pull the rest of the way back in.

This is what I got, not the best pictures.

Interesting. It would be a good option for guys running spacers on the street. Follow up when you install them.
