You should measure your current spring pressure and installed height to determine if .020\" provides the necessary preload without causing coil bind.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is coil bind and how does this shim help?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Coil bind occurs when the valve spring is compressed until the coils touch, which can damage your valvetrain. While shims increase pressure, they also reduce the available travel of the spring.
