These COMP Cams ID spring locators use a hardened steel inboard locating shoulder and a 1.300" outside diameter, intended to center valve springs such as COMP part numbers 26921 and 26926. The locators protect the head and shim from spring pressure while delivering consistent spring positioning, making them suitable for direct replacement and valvetrain builds that pair with those specific COMP springs.
