Hi,

I am wondering if I need longer wheel studs if I get aftermarket wheels. If I do, what length do I need and where can I get them from?

Thanks in advance,
Carlos

Not if you order the wheels in the correct fitment.

Supra GTR,

Thanks for the information! That is very helpful.

Carlos

longer studs are needed if you run a 7 to 10mm wheel spacer. Longer studs are cheap and easy to come by, the ones in mid 80s toyota trucks are almost a straight drop in. They're identical except they're 7mms longer and the splines are a touch longer then needed and need to be filed or grinded down to match. Heres a pic...

Toyota Land Cruiser studs are about 3/8" of an inch longer (pn#90942-02052). If you get proper fitting wheels you shouldn't need longer studs. You'll probably have to buy new lug nuts. Especially if you are still on factory wheels.

do NOT buy those from toyota, the landcrusier studs are the same ones as I was talking about (they're used in many of the trucks as well). I discovered that they were the right size with the help of a friend at Toyota. So I ordered 16 of them then and there because I made the classic mistake, how much could a bolt possibly cost from toyota? Well 80 bucks later I found out when they arrived. They were special ordered too so my friend would have gotten in trouble if I didn't buy them. Most studs at an auto parts stores go for a buck or two, get them there. My friend gave me them at pretty much the dealers cost and they were still over 5 bucks each, list was over 8 (keep in mind these are all cdn dollar figures, though these days that isn't as much a difference as it used to be).

Thank you all for the feedback. That is really helpful.

Carlos

what year landcruiser should the studs be ordered for?

Sorry to kick this back into play but Ill be needing studs for my rears as the rewinds at 0 offset make the wheel look like there too far inside.

So if anyone can give me a part number for like auto zone or parts america.

Thx and Ill look into it on my end as well.

PS. I may need them longer!!! :mofomad:

www.technotoytuning.com for your spacers!

I already got the spacers.

As for the studs I called Auto Zone and Parts America and both say theres 2 kinds listed.

ask them what the difference is, and if they tell you they dont know... tell them to find out.

Some good info on this old thread, so I just wanted to add to it.

I'm planning to replace my factory wheel studs with longer units, and wondered if anyone has tried freezing the new studs prior to install into the hub. Thinking that the lower temp of the new studs might make it easier to install. Also, wondering if heating up the hub mounting surface with a propane torch might help too.

I've changed a few studs before, just bang them out with a sledge, and pull in the new studs with a big lug nut and some washers. Seemed to work ok, but I'm always looking for a better or easier way. Will be changing out all 16 studs, so ease is good!

Thanks!

Wow I never ended up doing this. I have a new wheel stud from Toyota now and Ive been doing comparisons for matches.

This might be able to help those that can make sence out of these numbers. And if anyone can let me know so I can go get mine as well.

This is the way we've always done it. I guess it wouldn't hurt to freeze the lugs, but if you heat the hub you risk melting the seal, if you haven't removed it.

hmmm, good point on the heating. Thanks.
Maybe I'll just try the freezing step for install.

Well no ones come around on getting these on so I looked once more into Auto Zone and now came across these. I dont know my "SHIT" on any of this so maybe someone can tell if there any longer.

1st. Link http://www.autozone.com/R,NONAPP22583/store,2835/shopping/accessoryProductDetail.htm

2nd. Link http://www.autozone.com/R,NONAPP22584/store,2835/shopping/accessoryProductDetail.htm

The second link is 3" long. The first link is 2 7/8". Both use 1/2-20 threads, unlike our cars which use metric M12-1.5 threads. Is that what you wanted to know?

Yeah. So in other words these wont work with anything thats made with our thread pattern.

Pretty much.

What would be the problem using those and just getting lug nuts with the proper threading?

You could do that, but if may open the door to a big PITA.

If the holes the stock ones press into are smaller than the Standard stud hole, you could aug them out, and hopefully the bolt holes in your wheels will be large enough that they'll fit the standard stud. Then you're right, proper nuts with standard threading should work.

But, if the metric press fit holes are larger than the standard stud needs, you're looking a re-drilling the hub.

It'd be easier to just get metric studs, and probably more cost effective.

Here is what DORMAN shows for stock specs (someone confirm):

Knurl Diameter: 14.22mm
Thread Pitch: Right
Shoulder Length: 8mm
Thread Size: M12-1.5
Length: 37mm
Type: Serrated Stud


For reference, the 87 supra stud length is 40mm which could possibly work for a simple 5mm spacer.

After crawling google for a while, I couldn't find a 47mm stud with the same knurl diameter.

What I did find is a 63mm stud that is popular in the UK. That could work for bigger spacers and using an open ended lug nut.

So for reference, what you are looking for is a 12x1.5mm stud, 14.22 (aka 14.3) knurl, 8mm shoulder, and longer then 37mm.

The ARP wheel studs shown above converted to mm are :

ARP PART # 100-7718
Knurl diameter : 14.351
Length : 58.436mm
Shoulder Length : 8.255mm
Pack of 5 : List price $85

BTW if you are calling around and want to deal in inches, you would want a stud that is 1.85" long (for a 10mm spacer)

Hope that helps!

Thank you Robert. That helped allot. Ill look into this with all the info you just provided.

Robert what did you use to convert that to MM??

Math.

Lol.

inches x 25.4 = mm

OK Did the Math on the Lexus ones at ARP they came out to Knurl diameter : 14.1732

Ill do the rest and post up if I came out with something thats close to it.

is there anyone that was able to find a stud long enough for a 20-25mm spacer???

Um, that size would come with studs in them.

Um, that size would come with studs in them.

I'm having them custom made... and according to the guy that will do it, it would be better to simply use longer studs.... if I can find any.

Those will not be long enough for a 20-25mm spacer... So far... I only found some that will work with a 10mm spacer...

I'm having them custom made... and according to the guy that will do it, it would be better to simply use longer studs.... if I can find any.

I've had a 20mm wheel adapter custom made before.
It came with the wheel studs. It's just four more holes that are slightly countersunk to put the M12 1.5 studs in.
At 20mm thickness, you have to use short open end acorn nuts to secure the adapter to the wheel hub.

Actually, I could use a pair of 20mm hubcentric adapters if you are doing a run - PM me.

Ken

DML, that response wasn't for you, obviously.

I'm have a kit custom made for my car since I dont want to spend 3k on wheels this year. I could have some more sets done, but I don't know the price yet.

If we can find wheel stud long enough, it would be easier and cheaper to build the spacer.

I'll pm you when I have more infos...

These may be long enough (70mm):

If they will work, let me know how much your 'inexpensive' 20mm spacers are (60.1mm centerbore).
I've can just ship you the studs USPS (gift) for the studs to avoid brokerage fees and gst :).

FWIW... I couldn't cross that Dorman # at my local jobber, but found this
DORMAN Part # 610414 and it is the same stud.

same here, seems the part number change... local auto part wasn't able to find part#98521, but in there catalog, all parts number are 6 digits and they found 610-414.
