Wheel Stud Spline Dilemma!

[DirtyS14]

Ok guys, I ordered some 15mm spacers from option imports. The spacers came with extended studs. I made certain they were for the FRONT of an S14. Since I know that the knurl sizes differ from front and rear. Anyway I got the correct spacers, the part # on the box and the spacers collaborates with the spacer kit for the FRONT on Ichiba's website so that all good.

I pulled out my old studs and they have 36 splines vs 30 splines on the studs that came in the ICHIBA box. My car has bone stock hubs btw. I didn't install the 30 spline studs, instead I phoned up option and explained the situation, they sent me the 'correct' set of studs which again have 30 splines.

The guy at option said that he has the 30 spline on his S14 and they work great. Is it ok to install these studs even though they have the wrong pattern?

whats a spline? are u talking about the thread pitch? as in 1.25 or 1.50?
sorry just trying to help, but iono what spline is haha

[DirtyS14]

Basically the splines/teeth/keys on the studs that keep it from spinning when you insert it into the hub.

Basically the little slits that keep it still.

Not the threads but the splines.

Do they line up? I know it's probably a little hard to tell, since they dont exactly slide right in... The only thing you need to worry about is it holding that stud in place. The last thing you want is to get all your lugs torqued and then have one spin on you trying to get it off.

[Koopa Troopa]

If they fit they fit... If not then.... However in the picture that looks like a rear stud..

BTW What the fuck wheels you using that requires a 67mm stud?

They may line up. The splines of these studs are thicker than the stockers which kinda makes me think it will mess stuff up. I guess I could force them in and try. Maybe if someone on zilvia has installed these 30 spline studs they can tell me if they lined up or not... thats what I was hoping for.

If they don't i'm going to mess up my 5-lug hubs, son. And I don't want to take that chance but ichiba and option imports claim it will work. It just doesn't seem right.

That was a random picture off the internet to explain to the guy what splines I was talking about. My studs are 15mm longer than stock.

[5t341tH]

well i dont know about 30spline and all that but for s14 front, u need 14mm knurl and s14 and s13 all around is 13mm knurl (the knurl is the part u are talking about)
s14 front- 14mm
s14 rear/s13 all around - 13mm
so u need 14mm knurl.

i have installed 14mm knurls in my front and 13mm in my rears. works perfectly. i bought em off that site too. gl i hope thats your problem

So you have 14mm Ichiba studs with 30 splines and they work perfectly?


If anyone has nismo extended studs outside of their car, please help me out!

If you have NISMO extended studs for an S13 or 14, please count the splines at the head of the studs. Do you have 30 splines or 36 splines?

[lazierhobo]

just check the fit on the hubs, its designed to be an interference fit, if they slide in easily then they are the wrong size, if you have to press them in, then they are the right size.

the splines arent cut into the hubs so the fact of 36 vs 30 doesnt change things, so long as its a interference fit you will be good to go...if your really worried you can lock-tight them in or put a small tack weld on the back.

FRONT:
Moroso Wheel Studs
Wheel Studs, Press-In, 7/ 16-20 in. x 2 7/ 8 in. Long, .560 in. Diameter Knurl, Set of 5

REAR

ARP Wheel Studs
Wheel Studs, Press-In, 12mm x 1.5 Right Hand Thread, 0.509 in. Knurl,



Get all 4 corners done for under 50 bucks. Only downfall is that you need different lug nuts for the front and the back, but I don't care. They share the same 3/4 socket, so if you don't like a bobo and kick your nuts all over the floor, you'll be ok.

i counted my front studs and there are 36 splines. the ones in the back, i have yet to count. hope that helps

[dino6192]

thats weird, same thing happened to me. I ordered 60mm studs and thought they were all the way in, drove fine on the streets and wheels were tight. after about 4-5 runs at the track my wheel got wobbly as hell and almost fell off! after looking closer I realized WTF was I thinking for pressing a 30 spline into a 36??? do as you please.

[INeedNewTires]

get a caliper and measure the knurl on the aftermarket studs and the oem ones... i bought a set of H&R i'll count the splines tonight and let you know.

Cool cool, and they are Ichiba studs right? If so then I can phone them up and tell them to correct their mistake. Thanks a lot dude!

Holy crap!!!!! Yeah I need the right ones as its a drift car...... don't want my shit falling off and in the process fucking up my 5-lug hubs.

That would be really helpful, thanks man!

Yeah the knurl is 14mm, which is good, its just the splines are off.

Codyace, its not that I wouldn't buy new lugs to match those studs, its the fact that I paid Ichiba for extended studs for my car and they keep on sending me incorrect shit. Its their mistake and one that needs to be corrected. If nothing else I will follow your suggestion. Thanks.

[BustedS13]

they just smoosh in. put it on, throw a few washers on it, and torque down an acorn lugnut with an impact gun. that's it.

I was thinking about it.. wouldn't I mess up the stock pattern? So basically If I wanted to go back to stock studs I would have to buy new hubs...

If the 30 spline ones line up by skipping splines then thats cool... i just need to confirm with ichiba. The guy up there claims his shit came loose. And one other member claims that ichiba sent him 36 spline studs. I don't want to do this half-assed and then have my wheel come off later on and endanger myself and other people.... with a crucial part like this I really want to be sure that its completely legit to use.

I really think ichiba sent me the wrong equipment... which is why i'm frustrated. First they told me the spacer/studs were on backorder, my car sat for a month. Then they finally got them and sent me the wrong studs. I complained and they sent me the wrong studs again and my car is still sitting.

[alkemyst]

the splines on studs are to just provide an interference type fit. The original bores are manufactured smooth. Diameter is what matters.

Now to much pulling and refitting of studs will cause the bores to wear out and the studs to spin.

[orion::S14]

^^^ Yep...there is no 'correct' spline count.

The hub holes are basically smooth...and as he stated, the splines just kinda smash and hold the stud in.

This isn't like a domestic axle, where spline count matters.

The ones you have will be fine.

[INeedNewTires]

dude really wierd, My H&R studs have 45 splines!!! i'm kinda freakin out now, havent installed em yet but shit, how can they have that many? and usually that means the teeth are smaller so they may not hold as well as OEM teeth.... didnt measure knurl dont have a caliper here but they look the same.

Oh wow I never knew this! Cool thank you guys very much!!!!!!!!! :bigok:

[DirtyS14]

Thanks for your help dude! It seems that both our studs should work fine as long there is sufficient interference.

Thanks again guys! Saved me a lot of frustration! :cool:

[jeffc8486]

I know this thread is old as hell, but i just ordered some ichiba 15mm hub centric spacers and tried to install the new studs that came with it and they dont fit in my hub they just push right in, i think the knurl diameter is wrong. I looked at the stock hub and its a little bit thicker around the knurl than the aftermarket one. Do you think that a tire shop would have different type of studs??

[[email protected]]

Old threads never die... but I'm going to add for completeness

The nissan 13mm knurl is 32 spline, ideally your wheel stud should match, or you will end up tearing out some metal from either the stud or the hub when installing them

The side effect of this is they are harder to get seated all the way, and will take many cycles of torquing and driving to finish the job... however you can use a counterbore bit to bevel the backside of the stud holes to give that material somewhere to squish

And I'm going to repeat this as a manufacturer (yes I have extended studs for nissans): NEVER use an impact gun and wheel nut to draw in the studs, ALWAYS press or hammer them in (I recommend carpenter's hammer)!

Is this true? A friend of mine said that there are supposed to be splines on the holes on the hub to match up with the splines on the studs. If the holes on the hubs come smooth and spline-less from factory then hell yeah.

[[email protected]]

Only in the sense that you do less damage matching the old ones, otherwise you will wear out the bore and it may not grip the next one

Since people do snap studs (usually from over-torqueing) it's safe to say many get replaced more than once

But barring damage, you just want the ideal spline size for the hole, for a Nissan, a good rule of thumb is: .008" or .2mm over

You can get away with a bit more (.010" or .25mm) on aluminum or softer cast iron hubs

[anti tyler]

It doesn't matter. Pound it in and drive off into the sunset. 34/36/40/80 splines, never-the-less it will be fine


If they fit they fit... If not then.... However in the picture that looks like a rear stud..

BTW What the fuck wheels you using that requires a 67mm stud?



Wheels that have spacers on them. That's what requires longer studs....

Figured that was a dead give-away but I guess not.
