Product Details

The COMP Cams 4818-8 guide plates are precision-engineered flat, one-piece steel guide plates designed specifically for Ford 289-351W small block V8 engines. These guide plates ensure proper rocker arm geometry and valvetrain alignment for optimal performance and longevity.

Key Specifications:

  • Designed for Ford 289, 302, and 351W small block engines
  • Fits 3/8" diameter pushrods
  • Compatible with 7/16" rocker arm studs
  • Flat, one-piece steel construction for durability
  • Sold as a complete 8-piece set (one per cylinder)
  • Maintains correct pushrod alignment to prevent wear

Guide plates are essential components in performance valvetrain systems, preventing pushrod deflection under high-RPM operation and ensuring consistent valve lift. The flat design provides a stable platform for guideplates in applications using screw-in rocker studs. COMP Cams guide plates are manufactured to precise tolerances to ensure proper fitment and reliable performance in street, strip, and racing applications.

<br><br>Borgeson 000940<br><br>I found Autoplicity during a price search on the Borgeson steering shaft for my truck. I had never heard of them, and was a bit skepticle. But after doing some research, found that Autoplicity has a good reputation on a Jeep forum I visit.<br><br>I decided to order, and I am impresed. Extremely fast shipping, I placed my order on Saturday, and its now Monday before noon. I am holding the new part!

I ordered a distributor part number 30001 and Autoplicity had the best price I could find. I havent recieved the part yet but I should be seeing it in the next 2 days. Great Price and Fast Shipping!!!

Best price around. Great Communication. Fast shipping. What else can I ask for?<br>I have already purchased again from them.

Quick shipping and they had the fuel jugs I needed for the best prices thanks!<br><br>UPDATE: they were so good I made another order with them within a week.

Great Pricing (lowest i can find anywhere) and Quick Shipping, Product has no damage from shipping! Thank you Autoplicity!

I received my ARP head studs as described and on time with zero problems, and cheaper than anywhere else.Will use again!!!

We ordered a cover for a pickup truck bed and were so pleased that it was shipped so quickly. The price was the lowest that we found on the internet or in any of the stores where we looked. We were notified by e-mail as soon as it shipped. We will definitely shop this site again.

First time buyer from Autoplicity and found the website easy to navigate and find what I wanted quickly. They had the best price of all the other sites I checked, including shipping.
