My trucks supposed to have arp studs in it but they look stock someone told me today..i boughtt the truck with all this stuff on it i was told by the guy i bought it from,,,ithe guy i bought it from gave me the number to the shop that did the work to it and i called them they told me arp made head bolts at one time..does anyone knw if this is true?? On the top of the bolt i can see it says /// 12.9. Can anyone help me ? Those are the head bolts on the out side of the valve cover right?

 

Your thinking is correct, those are not studs.

 

Are the head studs under the valve cover??

How do i know if i got arp i dont understand im dumb .......

 

The row of bolts beside the rocker cover are some of your head bolts. If you had studs, you would see this style:

 

Oh,,geezz mine dont look nothin like that....could it bepossiable arp made ones that looked like that?? No hey?

 

Not a chance.

 

Cause like i said i well emailed the shop that did it to ask and their words we're arp made ones like that and that their high tensil steal??? Whats that sound like to you??? this is the shop that did it....manjinmechanics.com. Check it out it was their shop truck

 

Also the 12.9 you see on the bolt is the grade of the bolt.

 

Well tomoro off to the shop here where i live to see if this things really got what the guy i bought it from says it has....oh man im gettin mad this is going to suck if i vot taken for a ride.....man now im starting to dout that the tranny is done cause the shop also said it was all done too.....

12.9 is the stock grade bolts used from the factory, It is however a very strong bolt.
