The 4712 features a 1.400\" OD and a .520\" ID.\u003c\/p\u003e\u003cp\u003eThe old standard shims will not hold up to the extreme spring pressures and high RPM in today's race engines. COMP Cams offers a simple but effective solution to this problem. These Valve Spring Locators provide a thin, hardened Steel alloy seat that will not only protect the head and shim, but also locate and hold the spring in place. Previously, this part has been available only in a cup form with the retaining portion being on the outside of the part. This required that the head be machined a great deal to accept this cup so COMP now offers an ID locator with the locating shoulder on the inside, as well as the spring cup.\u003c\/p\u003e\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eLocator Inner Diameter\u003c\/strong\u003e: \u003cspan\u003e0.52\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eLocator Outer Diameter\u003c\/strong\u003e: \u003cspan\u003e1.4\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eSpring Inner Diameter\u003c\/strong\u003e: \u003cspan\u003e0.69\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eAmazon ASIN\u003c\/strong\u003e: \u003cspan\u003eB001G8OFP6\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eC.A.R.B.
