This set of COMP Cams GM Duramax spring locators supplies hardened steel lower seats that center and hold valve springs in Duramax cylinder heads. Each locator uses an inboard locating shoulder to position the spring and protect the head and shim from elevated spring pressures. The set streamlines assembly while avoiding extensive head machining required by older cup-style retainers.
