If you have ever installed a rocker stud into a cylinder head
and watched it wobble as it screwed in you knew from the beginning
that the rocker geometry was going to be inconsistent all over the
place. ARP rocker studs are concentric within .005
T.I.R. thread pitch to thread pitch. They run-in straight and true.
Lengths are exact designed to provide positive seating every time.
An extra-large radius base offers greater resistance to flex.
Available in both High Performance and Pro Series models.
NOTE: Not to be used with
OEM-style, self-locking nuts. To be used with ARPs
patented Perma-Loc adjusters
Made of 8740 chrome moly forgings and heat-treated to 180,000 psi.
Excellent for E.T. Bracket Racing, limited rule oval track
competition and street use. Tip ground flush for optimum adjuster
Designed for competition applications, ARPs Pro Series rocker arm
studs are made of premium grade 8740 chrome moly steel and
heat-treated to a tensile strength of 200,000 psi.
It is highly advisable to determine what the optimum rocker arm
stud length is for your particular application. This is especially
true when long pushrods and valves are employed you should raise
the installed height of the rocker arm to compensate for the
1.300 Exh./0.820 Int.
Base thread length is 1.300 in. exhaust, 0.820 in. intake.
Sold as a set of 16.
I looked for hours and this was by far the best price I found anywhere. Told all my friends about it. Thanks Autoplicity!

I ordered an AEM intake from Autoplicity because they had the best prices but it was on backorder from AEM. Autoplicity emailed me to let me know right away and sent me a confirmation when it was back in stock. I'll be shopping here again!

No issues at all and a very good price to boot. What could be better? Will definitely order from them again.
