The COMP Cams CNC spring seat is a hardened steel inboard locator that centers and holds the valve spring while protecting the cylinder head and shim under high RPM and heavy spring loads. The 4711 seat measures 1.550" OD and is intended for .570" guide applications, matching COMP valve springs like the 26095. It provides a thin, durable seat option that reduces the need for extensive head machining.
