Does any one know what the part number for ARP headstuds are? also does anyone make main studs?

 

231-4701 arp head studs. We do carry them in stock...

 

thanks a lot that is what i found, is there any main studs out there or am i stuck with the stock bolts?

 

there are main studs http://www.summitracing.com/parts/ARP-209-5401/

 

why does summit have them for less than $100 and OTTP have them for $300?

Josh/Sean/John - can you help answer for me? I was gonna buy these but want some insight.

 

subd, im goign with bates tho

 

300? I thought they were 419$.

I was wondering the same.

 

I do believe that the LSJ part number for head studs is actually ARP 209-4701. The part number you have displayed is for the 2.2. I dont know maybe a mix up.

 

Do not get these for the LSJ I ordered these and started to build the motor last night and they are about 3 inches too short note that these are for a 2 bolt main this kit includes 10 studs the main girdle of the LSJ requires 20 of one size and 10 of another

ARP Does not make a specific kit for headstuds the ARP 209-4701 do not work they are a different thread pitch i called ARP this morning and they notified me of this. If you look on turbotechracing.com they show the ARP 231-4701 as head studs that fit the 2.0 2.2 and the 2.4 Ecotec

 

Exactly, the 231-4701 works with ALL ecotecs in the cobalt, do not get any other part number

 

Really? I am so glad I bought them and they are on there way... This blows

I was worried about this because I didnt see a quantity or anything. I just looked it up too, they are for a opel/vauxhall...

 

yeah retarded eh?

 

I called summit to tell them this info, since I didnt even see that it was for a 2 bolt main (weird I would trust that when it says 2.0l chevy saturn) They said that is what ARP specs. I said well there is 20 main bolts that came out of my block, how many are in your kit? After him still saying that ARP specs that exact setup for our car he put me on hold for 5 minutes. Then comes back saying I guess its for the opel 2 bolt main, you will have to refuse shipment since its already in route then they will refund me... what a hassle.

 

i stand corrected. Thank you for the advice before i went and bought the wrong stud kits...

 

great information...thanks for the heads up!

 

whod u talk to if u dont mind me askin? if u remember by chance

 

I went with bates engineering studs

 

IDK, I just talked to someone in the sales tech line or something in that area. Not too sure. I just hope they take off that the stud are NOT for our engine. It has to be hurting them especially because I am going to refuse the package and get a full refund. Now they pay that shipping charge? Seems like a waste.

 

i will make sure it gets off ... and yeah we pay the shipping charge if its our mistake

 

sorry to bring this thread back alive. but any one know the arp main studs torque numbers. caint seem to find them.

 

Wats the part number?? Theres no arp main stud kit for the ecotecs

 

There's no kit. U have to order each one check first post of thread.

 

Ya ive bought it they r to short.
I have part numbers for the correct length studs.
