I need wheel studs for factory unicast disk brake rotors that are about 1/4 inch longer than stock. I've never been really comfortable with the little bit of thread sticking out through my aluminum rims and since I have everything apart it seems like a good time to swap them out.

Is there a source/part number/application that will work for me that someone can post?

Check out Dorman products. I used to have a part number for a 2" stud with the correct sized knurl, but can't find it. They have many lengths available

Wasn't there a stud for a Lincoln that was longer?

Huge assortment at Jegs.

Ha! This is the one I was thinking of - Dorman 610-290

Nice find, what is the length of the factory studs?

I don't have one out to measure, but on a rotor about 1-1/16 inch of thread showing - so I'd guess 1-5/8 overall.

For me, it's simple. I use 3" studs with open ended lug nuts.

Thanks for looking that up trackpack! ORielly had them in stock local and they are already on the car. Here's a couple pics for reference. Long on is the dorman part trackpack showed, middle is out of the large rotors from Dr. Diff's kit, and the old one with the massive head is from I believe a stock A body rotor I did the disc swap with years ago on my challenger.

Once I cut the quick start nub off end they were the same length of thread as the screw in studs on my Dr. Diff axles. Probably had plenty of engagement already but since you can't see with closed end nuts and my aluminum rims are way thicker than stoxk steels, it was worth it for peace of mind.

Glad it worked out.

NHRA rules say the stud must extend out of the lug nut equal to or greater than the stud diameter. I doubt any tech inspector bothered to measure it though.

I've noticed Dorman has declined in quality, I wonder if those studs are the right hardness.
