Product Details

ARP 135-7222 Rocker Arm Studs

Rocker Arm Studs
High Performance Series
2Pieces

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.

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.
