A set of COMP Cams spring locators featuring the 4690-style inboard locating shoulder and 1.253" outside diameter, supplied to center and hold valve springs while shielding the head and shim. These hardened steel seats let you locate springs internally rather than using an external cup, reducing machining and providing consistent seating across multiple valves in performance or rebuilt cylinder heads.
