Help, I have a 2001 superduty and bought these wheels from a 2005. I'm using the 2" spacers with the correct hub centric design. When I bolted a couple on yesterday, I noticed the lugs dont screw as far down. I added a pictured. Is this ok? I pressed one out and have been looking for one about 1/2" longer but have found nothing. The studs are M14 x 2.0 and inside lip to end of thread are 2-3/8" long. Anyone know where I can find studs about 1/2" longer?
just wanted to make sure that u checked to see if your trucks wheel studs aren't sticking out past the flat of the wheel spacer
that would in turn hold out the wheel and make it look as if the spacers stud were to short
so u would be tightening the wheel against the original studs rather than the face of the spacer
i have had to cut the factory stud ends off on some trucks to keep them from sticking out from the spacers
I know quite a few of you will probably say “they worked fine for me!”, but I cannot stress enough how bad it is to use wheel spacers.
It is great to find a good price on some factory take-offs, but I would keep looking for wheels that you like AND scan bolt up without using spacers. It is an engineering no-no.

I agree with Dave 110%, with those spacers you’re definitely to thick. Second those studs are too short and you can start pulling the threads. There needs to be at least 1 & 1/2 threads above the nut.
I very highly suggest you do you do not drive it and if you must do not put any load or tow anything. Lots of people will tell you “Oh It’s Fine” and maybe they were lucky. Years ago a lot of people tried spacers and got to watch their wheels pass them going down the road. Also they will say that for years large trucks had them but those were engineered and definitely not 2” thick.

So I took the wheels back off right after I took the pics because I didn't want to chance it. The thread length on the studs is about 1.5" and if I could find replacement M14-2.0 studs atleast a 1/4" or 1/2" longer I would use them. So my next question is this. The hub thickness on these wheels is .835" or right at 21mm. Compared to the stock 16" wheels I've got on the truck they are about 3/8" thicker. The pic is of the 20" wheel hub thickness. Could anyone with another set of 20" factory wheels of another style check there hub thickness and let me know if others are thinner? Thanks
i take it the OEM studs didn't stick out past the spacers?
Sorry for not addressing this, but the factory studs do not come past the face of the spacer. They are recessed with no contact. Thank you for the suggestion.
So now I will try to press in longer studs. So my next question. The studs in the spacers have a knurl of 15.32mm max diameter (outside), and 15.12mm min diameter (bottom of the knurl). The stud I've found with the correct length has a knurl diameter of 15.98mm max, and 15.78mm min.
What size should I drill or ream the spacer bore to get the correct interference fit for these studs? The spacer is aluminum.
I have had 2" spacers on my truck for a few years without issue, as long as they are the correct spacers and properly installed they are as safe as any other part of the drivetrain and suspension, 95% of wheel spacers failures are caused by improper installation, or using the wrong spacers for the application. I am using my spacers with the factory 2000 model wheels and the lug nuts go all the way on like they should. In your situation I would suggest finding longer studs.

Yes, Im going to try to ream/drill out the bores to fit the new longer studs. BTW, The 2000 16" wheels have a thinner hub and they would've bolted up ok.
