The COMP Cams 4680 spring seat is an ID locator with 1.300" OD and .505" ID, intended for LS applications and specified for use with certain COMP conical springs. Made from hardened steel, the locator uses an inboard locating shoulder to center the seat and retain the spring, providing correct spring positioning where the .520"/.505" guide dimension is required for reliable assembly.
