COMP Cams Rocker Arms Ultra Gold Arc FS

If you're building a high-performance Ford small block, especially one that needs to handle serious spring pressure, you'll want to pay attention to the valve train. These COMP Cams Ultra-Gold ARC Series aluminum rocker arms are designed to be a strong, stable, and well-lubricated part of your engine's top end. They're built to improve engine power and valve train stability, and they feature an improved oiling system to keep everything running smoothly under load.

COMP Cams has taken their original Ultra-Gold design and made it even better with the ARC series. They used advanced analysis to create a new extrusion that's both stronger and stiffer without adding extra weight. The arced channel and contoured top give these rockers a great strength-to-weight ratio, and the CNC contouring helps ensure clearance with valve covers and springs. These are manufactured in the USA and feature a unique spiral lock clip to retain the trunnion, which is a more durable design than traditional clips. They're also designed to handle up to 700 pounds of open spring pressure, making them suitable for aggressive camshafts. You'll need to use screw-in studs and guide plates with these rockers.

This set includes 16 rocker arms with a 1.72 ratio, specifically for Ford 289, 302, and 351 Windsor engines using a 7/16-inch stud. They also come with revised locking nuts that offer a larger surface area to help maintain valve lash and reduce wear. COMP Cams backs these with a lifetime warranty, so you can be confident in their long-term performance.
