What is the spring pressure rating for these rocker arms?

These Ultra-Gold ARC Series rocker arms are designed for use with up to 700 lbs of open spring pressure. This makes them suitable for many performance street and racing applications.

What makes the Ultra-Gold ARC Series different from older Ultra-Gold rockers?

The ARC Series features an updated arced, recessed, and contoured design for improved strength-to-weight ratio and better oiling. They also use spiral lock clips instead of retaining clips and have revised locking nuts for better lash control.

Do these rocker arms come with all the necessary hardware for installation?

This set includes the eight rocker arms and revised locking nuts. You will need to ensure you have the correct 7/16" rocker studs and any other required valve train components for your specific engine build.

Product Details

COMP Cams is well-known for helping engine builders get the most out of their valve trains, and their Ultra-Gold ARC Series Aluminum Rocker Arms are a prime example. These aren't just any rocker arms; they feature an updated Arced, Recessed, and Contoured design that helps improve valve train stability and oiling, all while being manufactured in the U.S.A. This set is specifically for Chevy Small Block V8 engines with 265-400 cubic inch displacements and uses a 7/16" stud with a 1.5 ratio.

The engineers at COMP Cams developed these rockers using advanced analysis to create a body that's both stronger and stiffer without adding unnecessary weight. The unique arced channel and contoured top contribute to an excellent strength-to-weight ratio. You'll also find CNC contouring on the body to help ensure clearance with valve covers and springs, a common concern during installation. Instead of traditional retaining clips, these use durable spiral lock clips, and the included locking nuts are revised for better lash retention and reduced wear. They are designed to handle up to 700 lbs of open spring pressure.

This set of eight rocker arms is a solid option for many classic Chevrolet and Buick vehicles from the 1970s and 80s, including models like the Chevrolet Camaro, Chevrolet C10 Pickup, and Buick Regal. They come with a lifetime warranty, meaning COMP Cams stands behind their durability.
