Product Details

ARP rocker arm studs solve the common problem of wobbling, misaligned studs that create inconsistent rocker geometry. Manufactured from 8740 chrome moly forgings and heat-treated to 180,000 psi tensile strength, these precision studs are concentric within .005 total indicator runout (T.I.R.) from 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 for exceptional strength and durability
  • Precision-manufactured to .005 T.I.R. tolerances for perfectly straight installation and consistent rocker geometry
  • Extra-large radius base provides superior resistance to flex under high valve spring pressures
  • Ground-flush tips ensure optimum adjuster seating and stability
  • Exact lengths guarantee positive seating and proper rocker arm positioning
  • Designed for use with ARP Perma-Loc adjusters (sold separately), not OEM self-locking nuts

Specifications:

  • Overall stud height: 1.895 inches
  • Screw-in thread depth: .710 inches
  • Adjuster thread depth: 1.000 inches
  • Shank diameter and thread: 3/8-24
  • Base diameter and thread: 7/16-14

Ideal for E.T. bracket racing, limited-rule oval track competition, and high-performance street applications. When using longer-than-stock pushrods or valves, verify proper rocker arm stud length to maintain correct installed height and geometry.

Great price and good company to buy from!

I was apprehensiveness at first to make a major purchase with Autoplicity due to their extremely low price and lack of reviews. I decided to take the chance and I am very glad I did. I made my order on a Monday morning at 0900 eastern time and my product arrived on Wednesday at 3pm. The item was exactly as described and the most astonishing part is that my purchase was released from the factory less than 45 days ago. I was expecting a model that had been sitting on a shelf for the last year and needed to be updated. That was not the case. I will definitely order from Autoplicity again in the future.

I found what I wanted and it was overall a pleasant experience.

Very good price. Super quick delivery. Will def. buy from them again. Highley recomend them

Sweetest price on this K&N Filter anywhere! Shipped within 24hrs too. I'm coming back to shop for my car next.
