Product Details

ARP High Performance Series rocker arm studs deliver precision-engineered consistency for demanding engine builds. Each stud is manufactured to exacting tolerances, with concentricity held within .005" T.I.R. (Total Indicator Reading) from thread pitch to thread pitch, ensuring straight, true installation and consistent rocker geometry across all positions.

Key Features:

  • Manufactured from 8740 chrome moly steel forgings
  • Heat-treated to 180,000 psi tensile strength
  • Precision-ground tips for optimal adjuster seating
  • Extra-large radius base provides superior flex resistance
  • Exact length specifications ensure positive seating every installation
  • 2-piece set

Ideal for E.T. bracket racing, limited rule oval track competition, and high-performance street applications. The superior dimensional accuracy eliminates the wobble associated with inferior studs, while the large-radius base design increases rigidity under valve spring loads.

Important Installation Notes:

  • Must be used with ARP's patented Perma-Loc adjusters
  • Not compatible with OEM-style self-locking nuts
  • When using longer-than-stock pushrods or valves, verify optimal stud length to maintain proper rocker arm geometry and installed height

I found the best price any where for the Autolift 2.5 inch lift kit for my 04 Chevy Colorado. Autoplicity is an awesome place to shop for automobile parts and accessories.

Seamless Purchase and great communication

Great Price! Fast Shipping!

Cheapest place to buy the tires I was looking for. Fast shipping as well.

First off, the price was excellent and they communicate every step of the sale. Shipping was immediate and arrived promptly with the complete order. One observation is the shipping calculator is flaky. I had to revise the order during checkout and noticed it seemed to give a different price each time. 6 cans of satin black $12 add 6 more of gloss, $15 change to 12 of the satin then $24 cancel order and purchase 12 satin then back to $15

Great Prices and fast, fast shipping. I will definitely do business with them again.
