ARP Head studs soon availible (and a lot cheaper then what's currently availible!!!!)

[ScottWright]

I figured a lot of you guys would be interested to know (or mabye already know) that ARP will soon be offering head studs for the cummins. They will be made out of the ARP-2000 material which is 220,000 psi steel. (same strength material as haisleys 14mm studs) I got a part number from ARP. I'm sorry I didn't get the 12v one, but the part number for the 24v is 247-4202. I am not a dealer of anything, and since these are brand new of course I honestly can not vouch for their quality. But concidering ARP's reputation I'm sure these will be a great product. From a material yeild stress point of view they are about 15% stronger then the haisley 12mm studs (220 ksi vs 190 ksi) (I dont' mean to pick on haisley but they are the only one's I know that offer these things)



Anyway, I priced getting them from ARP direct and they were $486. But I went to summit and typed in the part number and they are only $354!!!!! It says they will be availible to ship after 5-28 on summits site.



This is all the info I have on these, if you guys have any more questions you can call ARP direct. I just figured I'd pass on the good news!!

Cool Thanks!

DonM from F1 Diesel helped in the development of these studs going as far as sending samples and providing measurements and data including the push for EDM allen head broaching. He recieved the very first shipment of the 24v studs and has them in stock now. Many of his customers have purchased these studs already for their trucks, myself included. Summits overwhelming buying power enabled them to sell these studs for Kmart pricing. Unfortunately Summit Racing did this with exhaust systems a year or so ago also but provided little to no technical support for the product. Looking at the retail price of 486 you can see no one is being overcharged even at Don's present pricing. Head gasket sealing is not a easy task in extreme conditions and a little technical support can go a long way. O-ring type, size, protrusion, etc. etc. are all critical specs that Summit cannot provide at the present time. BTW the part number for the 12v is 247-4201.

Yes I agree, summit is about useless when it comes to tech help. They can only point you to the manufacture. And Granted ARP is more then willing to give you specifics on there bolts/material/application, but even ARP isn't going to be able to tell you those types of things like



"... O-ring type, size, protrusion, etc. etc... . "



But who ever is doing the o-ring job better be able to tell you those things regardless of who's studs you use, or where you by them at.



Don for sure has done a lot to help out the dodge cummin's group, Especially with the EDM'd injectors that he offers,and if you live in his area, I'm sure many people would highly recommend him and his expertise. I don't mean to take any business away from anybody. I really just wanted to post the info for the guys doing it themselves so they could get a break on the price. That's why I purposely posted in the competition forum I figured most of these types of people are capable of doing work for themselves.

 

[ScottWright]

You know I just reallized a really strange thing? . . . did anyone else notice that the 12v cummins has the exact same amount of bolts as a v10 viper motor? The ARP part number for the 12v actually shows up as a viper head stud. . . strange? Too bad nobody noticed that they were the same until just recently, because it looks like the viper head stud kit can be had for about $300? Can anybody else confirm this?

 

[Piers]

When I talked with Summit, they said the

12v part # was 247-4203 @ $356. 39

24v part # was 247-4202 @ $352. 99

if ya want to spend $2500. 00 with ARP, they'll sell them direct for $342. 51, not really worth spending $2500. 00 for a $10. 00 discount.

It'll be interesting to see if the Viper studs are correct???

 

[J.R. Adkins]

I thought the 12v part # is 247-4201??

[Piers]

I see that is the number Nathen posted as well, maybe I got the number wrong?

 

[Floor It]

PIERS has the right part #'s. I agree with piers because ARP told me the same thing on the $2500. 00 buy in and the price was not very good! Mike at ARP when I talked to him 7 months ago had told me a whole different type of price range. Now this really SUCKS!

now ya know why a guy has to bust his butt to make a living with the deisel group... everyone wants something for nothing



Give the guys who support us a break and support them !!. . cause sure as God made green apples you'll be calling one of them to ask questions and use their knowledge. . 'bout time we gave them something back like a living... no flame meant to anyone here... I for one will support those who support us even paying a bit more for the parts is well worth the price of admission !

12v part # 247-4203 @ $356. 39

24v part # 247-4202 @ $352. 99

Gary, I agree with you.



You have to support the people who support the industry. We would not have the head bolts w/o Don, and Credit goes to him for his legwork.

I'm just a little confused

i bought studs about a year ago and they came in an ARP box and had ARP install grease included. what am i missing???

just wondering thats all.

[justinp20012500]

Stupid question, but I need to know...



I know the purpose of o ringing the head and block, but why not just use the stock head bolts instead of studs????

 

[Piers]

Higher clamp load, studs are less likely to stretch under heavy load

 

[T. Baker]

Aprox. what boost and timing require studs? If you aren't "o" ringed or fire ringed are studs any help?

I will soon have twins but I am going to stay below 45 PSI on boost. I'm going to leave my timing at 15*

 

[willyslover]

T Baker. . that is what Blair [BPine] did with his twins. . studded and no O ring. . testing out what would happen as he isn't interested in high boost levels just enough to use the power his 5er pulling truck makes . . sugggest you contact Blair



ON Edit... Blair is running Piers pulling twin set up... looked very good from early reports from Blair, seams like he said he gained 12 MPH on Baker Grade by Vegas at 1200 degrees

 

[F8LDOSE]

Another reason to use 14mm head studs and 150 pd of torque is to distort the cylinders so you get lots of blowby, then you can blow your tappet cover gasket. Or you could do it right and send your block to somebody like Piers who has a deck plate and have everything done right the first time.

 

[OPoole]

A torque plate so when you hone the cylinder walls they will be round. And we use one on all of the motors we build iam NEW to the diesel game but not to performance and hope to build more for the public and the deal with ARP is 25,000. 00 for the good price!

 

[Brandon]

i'll be honest with you I will support the people and their studs as they have been with us from the beginning screw them arp guys they would not support us 3 years ago when I first studded my block



so thank go to all the guys

block

haisleys

mitchells

russin and all the others back there who have got things done without big companies



this is not meant to offend anyone, but a big company that has been asked to do something years ago and WONT does not impress me... . on the contrary it offends me



read the thread from dc by Block... ... ... it gives amazing insight
