The COMP Cams 4706 hardened locator cup is engineered for high-RPM valvetrain service where spring pressures are extreme. With a 1.830" OD and .640" ID, this thin-steel seat holds and locates valve springs while protecting the head and shim. It replaces older outside-retaining cup styles that required heavy head machining and delivers consistent seating for a variety of COMP valve springs in demanding applications.
