Product Details

ARP 135-7202 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.

Autoplicity had exactly what I needed and at a fair price. My online purchase was fast, convenient and was shipped promptly. Definitely will be going back to Autoplicity for my future automotive needs.

ok so far

Fast, pleasant experience.

Quick delivery, great product

Very pleased with the service. Would recommend to others.

Outstanding transaction. I was amazed my filters were delivered in less than 48 hours from ordering. Well done!

Competitive Pricing

It was good quality and online experience

Looked around online everywhere for my spark plug set. Autoplicity had what I wanted at the lowest price. Thanks guys!

Great pricing. (Check on google and they were the cheapest and had great reviews.) Quick shipment and everything is as they said it would be.

Extremely FAST shipping. Ordered K&N air intake on Tuesday evening and item was delivered Thursday morning!! Item as advertised. The package got here before UPS could upsate the tracking number!! Great service!!

So far so good.

Awesome experience! Lowest price and product was shipped right away.

Found Autoplicity by doing Google search looking for Corsa Sport Axle Back exhaust for my 2008 GT500. By far the best price, even cheaper than other big companies with free shipping by far. Ordered them on Thursday afternoon and got them 24 hours later in NY with the standard shipping. Could'nt be happier.

This was my first order with Autoplicity. I was pleasantly surprised when my order showed up quickly and was exactly what I wanted. I will be buying from this company again. Thanks for the quick service and fair pricing.
