This Comp Cams cup adjuster screw replaces the factory set screw for Ultra ARC Ultra‑Gold and Ultra‑Aluminum rocker arms, allowing you to lock down the adjuster nut on ARC series rockers. It supports the extruded ARC rocker design that improves valvetrain stability and oiling efficiency. Use it when securing adjusters on applications where the ARC rockers are fitted to maintain valve lash settings.
