ARP wheel studs

[4WD Toyota Owner Magazine]

I've installed ARP's WSAU 558-1 wheel studs in our FJ Cruiser, but I'm not quiet clear on whether they will work with the 80. Anyone put them in?

Hey David

We installed them on our race truck

They were a cross part to a Mitsubishi EvoIII!

Worked great, but very long for a stock wheel

My .02

How long?

Running open end lugs and need another 3/8-1/2" to engage all threads on the lug.

The ARP studs for is300 should interchange as well. They're really a lot longer tho

 

[Delancy]

If running open ended lugs, shouldn't matter, should it?

Not sure the cost to machine down, but...

I know on the 80s, the front studs are longer than the rear studs due to the hub face being thicker. It might be that you've been given studs for the rear. I would definitely like to see the nuts wound onto the thread fully, for maximum safety.

You and I, both. Have other issues that have sidelined the 80, but hesitate to drive, as is.

Just hate to have to machine them down, yet don't know if protruding that far out is a potential issue, either.

Can't open ARPs catalogue on IPhone, to even know what lengths are available in the correct thread pitch, base, length, nor do I know the lengths I need to replace.

Do find it odd that the only stated " kits" are for an IS300.

I'd give a nut for a definitive ARP parts list for hub studs, knuckle studs, and wheel studs.

My eyes are stinging from either the ATF fluid spewed in them this morning, or web perusals.

Protruding through is no problem, but too long and they will hit the bottom of your socket/lug wrench/etc

 

[Delancy]

Good point.

Anyone know the OE wheel stud length?

How about the hub/knuckle stud?

 

[SOYLENTPLATINUM]

Front Stud;
12mm x 1.5 Thread
OAL 45mm / 1.78"
UHL 40mm / 1.57"
*Shoulder Length 8mm / 0.31"
*Knurl Length 5.5mm / 0.22"
Knurl Dia 14.4mm / 0.56"
Thread Length 30 mm . 1.18"

Rear;
12mm x 1.5 Thread
OAL 49mm / 1.93"
UHL 43mm / 1.7"
*Shoulder Length 29mm / 1.15"
*Knurl Length 0.35"
Knurl Dia 14.4mm / 1.57"
Thread Length 29mm / 0.47"

*In the ARP catalogue the "Knurl length" is shown to be the shoulder length regardless of how much of it is knurled. Catalogue attached.

I found that I can order studs for the front (ARP #100-7718) but that there is no 12mm stud with both the correct shoulder/knurl length and knurl diameter. you would have to basically run the rear on front studs, or change to a standard thread pitch. I figure there is a reason Mr T made the rear shoulder larger (9" vs 8" diff) and I didn't want to undo his good works (and pay the price). So going with OEM on the rear, I guess.

PS there is a "request part" form on ARP's site, if enough mud members request it, maybe they will make it? ARP | Official Website | Kit Suggestions - https://arp-bolts.com/p/kitsuggestions.php

Plenty of people have ran these arp stud kits in their rear hubs.

I just broke a set about a month ago.

This thread is referencing wheel lug studs.

 

[leonard_nemoy]

Haha, that makes more sense. I can't imagine why anyone would want to use ARP wheel studs.

40’s might end up just going oem but wanna do arps while I am in there.
