COMP Cams Rocker Arms Ultra Gold Arc SB

Starting with an arced channel and contoured top, these Ultra Gold ARC rocker arms from COMP Cams are built for strength and a good strength-to-weight ratio. They are manufactured in the USA and are designed to improve engine power, valve train stability, and oiling. The body has been CNC contoured to help with clearances for valve covers and springs, and a spring oiler channel runs through the body for better lubrication. These rockers are well-built for use with up to 700 lbs of open spring pressure.

The Ultra Gold ARC series uses an updated extrusion based on FEA analysis, making the body stronger and stiffer without adding unnecessary weight. Instead of retaining clips, they feature durable spiral lock clips, and stress-relieving radii have been added to key areas. Even the included locking nuts are revised to increase surface area, helping to maintain lash and reduce wear. This set is designed for Chevrolet 200-262 cubic inch V6 engines with 3/8" studs and a 1.6 ratio, fitting a range of vehicles like the Chevrolet Astro, C10, and Pontiac Parisienne from the mid-80s.
