These COMP Cams ID spring locators are hardened steel seats that use an inboard locating shoulder to center and secure the valve spring while protecting the head and shim under high spring pressures. The 4860-style locator measures 1.655" OD with a .570" ID, providing a compact, durable solution for demanding race and performance valvetrain applications where traditional shims may fail.
