Product Details

ARP 135-7201 Rocker Arm Studs

Rocker Arm Studs
High Performance Series

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

HIGH PERFORMANCE SERIES
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 seating.

PRO SERIES
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.

IMPORTANT TECH NOTE
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.

excellent service A+++++

As expected. Fast delivery

So far So Good

third party shipper, price was right.

Nice!

I am so pleased! Autoplicity had the best price by far for the item I ordered. I was not familiar with them so having the Paypal option was perfect. Over all I saved $30 on an item that was close to $100. Shipping was VERY reasonable and quick. I ordered my item on Saturday. They shipped it right away and I received it on Wednesday. I am definitely an Autoplicity fan and will recommend them to my friends not to mention our mechanic. He found the item I wanted on sale through another major company. Just to double check, I searched online and Autoplicity blew that company out of the water with their pricing and service for the exact same item. Very nice!

Receive my order fast and it fit perfect

Awesome product And fast fishing

I ordered a WeatherTech cargo liner from Autoplicity after finding the product almost $40 cheaper than anywhere else. Usually I'm suspect of the one company with a very low price but the high number of reviews gave me enough comfort to order. The product came in a large box and was shipped for a very reasonable price and arrived in four business days. The product is as described and I couldn't be happier. I will definately keep them in mind for future orders.

Excellent prices and quick shipping. Will definitely use again.

Fantastic prices and fast shipping!! Looks like I'm done with Jeg's and Summit!!

I am very pleased with my purchase from Autoplicity. Price was very reasonable and shipping was great!
