Product Details

ARP 234-7206 Engine Rocker Arm Stud

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. The solution ARP quality. ARP rocker studs are concentric within .005 T.I.R. thread pitch to thread pitch. They run-in straight and true, and the extra-large radius base offers greater resistance to flex. Lengths are exact -- designed to provide positive seating every time. These Pro series rocker arm studs are from premium grade 8740 chrome moly steel and heat-treated to a tensile strength of 200,000 psi. ARP's patented Perma-Loc adjusters (available separately) should be used, not OEM-style self-locking nuts. 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 longer-than-stock components. The dimensions for these studs are: 1.900 overall stud height, .850 screw-in thread depth, .850 adjuster thread depth, 7/16-20 shank diameter and thread, and 7/16-14 base diameter and thread.

  • Designed for use with ARP's patented Perma-Loc adjusters, not OEM-style self-locking nuts
  • Stud dimensions are: 1.900 overall stud height, .850 screw-in thread depth, .850 adjuster thread depth, 7/16-20 shank diameter and thread, and 7/16-14 base diameter and thread
  • Made from premium grade 8740 chrome moly steel and heat-treated to a tensile strength of 200,000 psi; designed for competition applications
  • Lengths are exact, designed to provide positive seating every time
  • Manufactured to high tolerances so they run-in straight and true, and the extra-large radius base offers greater resistance to flex

Can't wait to get this part

So far, so good. We will see how long it takes

My order was angled dignified I appreciate it. Thank you very much

First time customer.

Easy to use site and best price I could find!!!

Great service

I recently needed head bolts for my 408 stroker motor that I'm building. I searched the Internet and Autoplicity had the ARP Head Bolts that I needed. Great price and quick shipping. Will definitely buy from again!!

I found your site very easy to get around in.

Mazda cargo mat for the CX-9 SUV came within 1 week. Mat fits perfectly; just as described. Autoplicity had the best price listed for this product; we are very pleased.

Great prices for the springs I got. Def. the cheapest around! Everything was fast and straight forward.

I have searched the internet for the best pricing on auto accessories and ended up at Autoplicity. I tried everything to negotiate prices with some supplies and still got the best pricing usins Autoplicity without any hassles or delays. My invoice number 9314 shows that I got a great deal thanks to Autoplicity. I will be a returning customer for my future purchases.

Almost a perfect score! I was pleased with the customer service but knowledge about their products warranties was lacking. Other than that, the representative that I spoke with on the phone was great. He was friendly and had a good overall knowledge of the products I was asking about. Pointed me in the right direction because I couldn't be happier with my bike rack. They had the best prices, lowest shipping costs, and my order arrived a day early. Great website to work with. I will definitely be doing business again and spreading the word about Autoplicity.com.

I got all of my parts in and where happy with them. The website is about the cheapest around. Something about them really gives me a good feeling. :)
