COMP Cams Rocker Arm Ultra Gold Arc FS

Starting with an arced, recessed, and contoured design, these COMP Cams Ultra Gold ARC rocker arms are built for improved valve train stability and oiling. They are manufactured in the USA using a new extrusion based on FEA analysis, which results in a stronger, stiffer body without adding unnecessary weight. This design also includes additional CNC contouring to help with clearances for valve covers and springs, making installation smoother.

The body features a spring oiler channel running through it for better lubrication, and the trunnion retaining clips have been upgraded to a more durable spiral lock type. Stress-relieving radii have been added to key areas like the body, trunnion, and pushrod seat insert. Even the included locking nuts are revised to offer a larger surface area, helping to maintain lash and reduce wear. These rockers are designed to handle up to 700 lbs of open spring pressure and are a popular choice for a wide range of Ford engines, including the 289, 302, and 351 Windsor.

For installation, you'll need to use screw-in studs and guide plates. These rocker arms are designed to be a direct fit for many Ford vehicles and are backed by a lifetime warranty from COMP Cams.
