This spacer features a 1.732\" outer diameter for 1.568\" outer diameter springs.\u003c\/em\u003e\u003c\/p\u003e\n\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\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.732 IN\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSpring Inner Diameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.623 IN\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSpring Outer Diameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.568 IN\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eThickness\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.3 IN\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e See 4779-8 for a set of 8 seat spacers.\u003c\/p\u003e\n\u003chr\u003e\u003cp class=\"prop65-warning\"\u003e\u003cstrong\u003e⚠️ California Proposition 65 Warning\u003c\/strong\u003e\u003cbr\u003eCalifornia Residents: This product can expose you to chemicals which are known to the State of California to cause cancer or other reproductive harm.
