Longer Wheel studs?

Are they the same pitch thread ?
There is nothing currently listed with the same pitch that has a shoulder shape like the stock parts.
 
I used these on the rear of my FJ40.

The longer of the two is Toyota 90942-02079. The short one was the stock lug I removed.
 
ARP's Special Order fellow, a pretty sharp guy that I worked with years ago on another project, did not recognize that shoulder configuration. He commented that they had several non-cataloged Toyota wheel stud applications, but that none of them looked like these.
So far as I've been able to determine this shoulder config is only used in this application and only comes in one length.
 
ntsqd - bumping an old thread...

any possibility of getting longer front wheel studs made?

I'd like a dozen for my fronts if you can find them. I'm also looking at some spacers that have their own studs (1 1/4 is minimum right?) Any rec's on best ones if the longer studs don't pan out?

It's all spike's fault... 1/4 won't be enough when i eventually run my new rims. Now i also am thinking of 4runner caliper upgrade... thanks Spike! :flipoff2:

Thx!
 
ARP will make them. For 48 of them it was estimated to be about $900-$1000. I'm not sure how the economies of scale would work out. Could be that 480 of them would be quite reasonable, but given the low interest I wasn't going to spend the money.

I guess most just convert to one of the 1/2-20 racing studs and call it good. The shoulders on those isn't correct, but maybe it's close enough that it really doesn't matter? I seem to recall that both the wheel hub and the rotor have to be drilled larger. The hub more than the rotor.

thanks! Spacers it is... any rec's on which to get? Seeing a ton of options online and most are pretty $. 1" ish?
 
Sl33py,

I am running 1.25" wheel spacers and the thread engagement is a little bit suspect. With 1", I'd say you'd be fine. Depending on the wheels/brakes/etc you'll be running you can probably get away with less.

BTW, when looking for 4runner calipers check out CarQuest. I got mine for $33 a piece. Really good price because they do price-matching and will often BEAT the other guys' price. Good warranty as well.

Good luck.

Thanks Elliott! 1.25 spacers from where? I'm looking now. It's a long story but my custom BS rims don't fit in the front...grr... Oh well. I measured some stacked washers and 3/8-1/2" should work, but if i then add the 4runner calipers... so figured i'd shoot for 1" to make sure there is room.

i'm not sure how the spacers you have w/ there own bolts like these right don't fit well for you?

thx!!
 
Rob,

It's hard to explain really. Once the spacer is on the hub, only about half of the wheel stud is exposed to put a nut onto. It's not a straight shot hole (or else the spacer wouldn't be bolted to anything). I'm thinking, the thinner the spacer, the more wheel stud is exposed.

gotcha - in the recessed areas where you put the supplied nuts to secure the spacer to the hub?

that makes sense. Found them local, but will have to pay tax AND shipping...

anyone have good supplier/part # for 1 or 1.25" spacers?

:cheers:
 
Dang! I got the worng Moroso stud. The 46220 was the one that I wanted.

Note that the stock wheel stud has a total shoulder length of 1.344" The longest aftermarket shoulder length that I've found a dimension for is 0.900" long. That's ~7/16" shorter shoulder than stock. Since the stud first goes through the rotor and then the hub on the Mini's and 60's that could be a problem. I don't know for sure.

Links to the three studs that I've found thus far that could work. None of them has as long of a shoulder as do the OE wheel studs. All studs are 1/2"-20

Well I just had an interesting conversation with Dorman. They won't make them in a small qty., but if they get enough calls about the need for them then maybe they will make them. The nice lady that I talked to said that she'd made a note of my request and that they do go through those notes looking for new product suggestions.

You asked for front or rear or both?

And you asked if they stock them or will make them?

Just wanna know what magic words to use when I call...
 
Fronts, 610-264 is their part number for fronts. I asked for some that had a 10-15mm longer thread length.

BTW, Thanks for calling!

Bump - After a lot of searching I've also found there isn't a lot of good replacements. I couldn't believe it so I kept searching. Using the rear studs on the front of a 84+ gives you only 4.5 mm more length. Not a lot but maybe enough. That part is Dorman 610-312.

Dorman 610-312
Knurl diameter: 14.17mm Shoulder length: 12.5mm Length: 44.5mm Thread pattern: M12x1.5

There's also a lexus part with a really long shoulder length but gives 15 mm more length.

Dorman 610-463
Knurl diameter: 14.20mm Shoulder length: 26.6mm Length: 55mm Thread pattern: M12x1.5

Something's not right with the -463 stud's specs. The shoulder looks to be a lot longer than a little over the thread OD. At 14.2mm it is about 20mm (~11/16") shorter than the stock front stud's shoulder length.

Ah-hah! Looked at Dorman's page, they have a 26.6mm shoulder length. The 14.2mm dimension is the knurl diameter. Which is a problem because according to Dorman the stock front knurl diameter is 14.46mm. It also looks like the knurled portion might fall in the area where the OE stud is 14.529mm, which would mean that the knurl wouldn't work. Hard to say for sure w/o a sample to measure.

Summing up:
According to the Dorman page for the stock front stud, their p/n 610-264 the specs are:
Knurl Diameter: 14.46mm
Shoulder length: 25mm
Length Overall: 52.5
Thread size: M12 x 1.5
