{"product_id":"cca-rotator-eliminators-5","title":"COMP Cams 4779-8 - Seat Spacer Set for Big Block Chevrolet - 1.568\" OD, .623\" ID, .300\" Thickness","description":"\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 req uired 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\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmazon ASIN:\u003c\/strong\u003e B00062Y9TU\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eC.A.R.B.
