Product Details

ARP High Performance Series rocker arm studs are precision-engineered to deliver consistent rocker geometry and reliable performance in demanding applications. Unlike standard rocker studs that wobble during installation, ARP rocker studs are manufactured concentric within .005 T.I.R. thread pitch to thread pitch, ensuring they install straight and true every time.

Key Features:

  • Made from 8740 chrome moly forgings heat-treated to 180,000 psi tensile strength
  • Precision concentricity within .005 T.I.R. for consistent rocker geometry
  • Exact lengths designed to provide positive seating
  • Extra-large radius base offers greater resistance to flex
  • Tip ground flush for optimum adjuster seating
  • Ideal for E.T. bracket racing, limited rule oval track competition, and street performance

Important Installation Notes:

  • Not compatible with OEM-style self-locking nuts
  • Must be used with ARP's patented Perma-Loc adjusters
  • Determine optimum rocker arm stud length for your specific application, especially when using long pushrods and valves

ARP's High Performance Series rocker studs provide the precision and strength needed for reliable valve train operation in performance engines. The premium chrome moly construction and precision manufacturing ensure consistent performance under high-stress conditions.

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!
