ARP studs
« on: May 01, 2013, 20:54:00 PM »
Hi all , does anyone happen to have a list of all the different size studs that ARP have to offer .
Not happy with the head studs I have , and need to find longer ones .

M12x1.75 bottom thread @ 30-32mm long
M12x1.25/top thread

Overall length 110 - 115mm .

Thanks
Matt

Why don't you contact ARP direct? Also, out of interest what makes you think there's something wrong with what you have?

The Studs they do for the V6 main caps are about that size.

The best thing you can do is fill out this & email it to ARP as Mike says.

They will tell you closest stud they do that suits what you want.

Thanks guys .
Hours of internet searching have led me to an archived toyota forum .

It turns out head studs for the good old pinto are what I'm after .

Dave , I bought two sets of mains studs easter last year to use for the heads .
When I trial assembled the engine last year I felt they were a little short and mentioned it to engine man .

Now , after a painfully long wait - don't ask - he's getting on with it , and we were checking this out last night .
The mains studs are 101mm long . Head 61mm . Gasket , nut , washer approx 10mm .

If we use the full depth into the block to have 30mm of thread in use ( holes 40mm deep but no thread for the first 10mm )
then the stud doesn't protrude enough for the nut to fit on .

Pinto studs are 116mm long . Result .

Matt .

Going to speak to ARP direct now and confirm the info with them .
If they are indeed what I am after and also have M12x1.25mm top thread I'm hoping to
swing a deal for sixteen studs only .

Although Pinto studs are appropriate length they only have 25mm thread top and bottom .  :angry:
Have an enquiry with ARP now for suitable studs .
I'll post this up if they have an answer .

Right , as stated , found the info for Pinto studs being appropriate length .

Then I found this :

 AU3.965-1LB is 1.75 & 1.25 pitch 12mm the 1.75 has 1.200 inches of thread and the 1.25 has 1.125 inches of thread
 AU4.175-1LB is 1.75 &1.25 pitch 12mm the 1.75 has 1.200 inches of thread and the 1.25 has 1.125 inches of thread
 AU4.315-1B is 1.75 & 1.25 pitch 12mm the 1.75 has 1.000 inches of thread and the 1.25 has 1.000 inches of thread
 AU4.600-1LB is 1.75 & 1.25 pitch 12mm the 1.75 has 1.000 inches of thread and the 1.25 has 1.000 inches of thread
 AU4.900-1LB is 1.75 & 1.25 pitch 12mm the 1.75 has 1.000 inches of thread and the 1.25 has 1.000 inches of thread
 

These are individual stud part no.s .
The 3.965 is the stud used in the mains kit .
The 4.600 is used as Pinto head stud .

I then sent ARP a copy of their calc sheet .

Their reply was
  "Hi Matt ,
Your calc sheet shows a length of 4.544 inches. What I have is part # AU4.600-1LB THIS IS 4.600 LONG and is used in kit # 151-4201. this kit has 10 studs nuts & washers. You would need to buy from our dealers over there. here is a dealer list to choose from."
RonF

So Pinto stud after all .

Already have nuts and washers for the other studs and I've managed to find the studs in the states for $5.71 each !!
Just hope they will ship them over .

Matt

It's amazing how hard this info is to find.

Thanks Matt


I used for mine

AU6.230-2LB = 160.53MM = Studs from a Dodge 5.9L 24V Cummins Diesel
AU5.400-2LUB = 137.2MM = Studs from a VW/Audi 1.6L &1.9L Turbo/Non Turbo Diesel

But of course I have a thick bar to allow for lol!


AU5.400-1LUB = Is YB studs which are 137mm long.

Do the Pinto studs go thinner in the middle or not?

I don't know if they are waisted or not yet .I'll let you know .

Trying to get some over here now . Engine guy deals with coordsport a lot so fingers crossed .

I spoke to two companies in the states . One was $5.71 a stud with the other at $9.51 a stud ( cheapest I could find ! )

Including shipping                                             $324.00  :'(                  over $700  :-X

I find it a little silly ARP don't just provide a listing for every stud they do !

ARP studs and bolts are getting very expensive lately, even the us. crowed in the states is already complaining about it.

To give you a example, I have used ARP studs and bolts true out my 427w build. The bill for just the bolt and studs internal (rods, main and head studs and a few others) = 1117.18 euro (that's $1366.75) including the shipping cost and tax.

Coordsport as useless but unfortunately they have the uk dealership for alot of gear.they need to improve on there customer service as i have had several incidents of chasing them as they are crap at returning calls.they lost out on potential income from me.cant stand companies like that.

If coordsport can't help then I'll just get two stud kits from raldes .
I bought a lot of the engine parts from them .

Fingers crossed though as engine guy gets a good deal with coord.
