Product Details

The COMP Cams 4852-8 guide plates are precision-engineered flat, one-piece guide plates designed specifically for Pontiac V8 engines. These guide plates ensure proper rocker arm geometry and pushrod alignment, which is critical for optimal valvetrain performance and longevity.

Key Features:

  • Flat one-piece design for consistent rocker arm geometry
  • Compatible with 3/8" diameter pushrods
  • Designed for use with 7/16" rocker arm studs
  • Application-specific fitment for Pontiac V8 engines
  • CNC-machined for precise pushrod alignment
  • Sold as a complete set for engine rebuild or upgrade

Guide plates are essential components in performance valvetrain systems, preventing pushrod deflection and ensuring that rocker arms operate at the correct angle. This results in reduced wear on pushrods, rocker arms, and valve tips while maintaining consistent valve lift throughout the RPM range. The COMP Cams 4852-8 set provides a direct-fit solution for Pontiac V8 builds using the specified pushrod and stud dimensions.

Great prices and quick shipping! They kept me informed of when the item was shipped also. Couldn't be happier!

Great prices. Great live customer service. Very pleased, will definitely order again.

Lowest prices I found on the net and great customer service! Fast shipping too!

Nice website, easy to order

Excellent service. I called in Monday for a hard to find item which I had ordered from several other online shops who despite saying were In Stock online were not actually in stock at all and the orders were canceled after waiting a week to find out. They had the item in stock as listed on their website and shipped the next day. The price was the cheapest of anyone who actually had the item in stock by a substantial amount.

Its amazing the prices Autoplicity is able to offer some of their products at. The product i ordered was consistently msrp on every site i searched through, yet autoplicity had it for $10 less. Lowest price along with a attractive and intuitive website is a win in my book. Having it shipped in less the 24hrs is another bonus

Lowest prices with quick processing and shipping. Very happy and will shop again!

Love that item was the cheapest found anywhere and that I could use Amazon checkout!

Best price around, very fast shipping and great service! I will buy from them again!
