{"product_id":"comp-cams-id-spring-seats-1-55-x-630-x","title":"COMP Cams ID Spring Seats 1.55 X 630 X","description":"The 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.","brand":"COMP Cams","offers":[{"title":"Default Title","offer_id":52578541830451,"sku":"CCA4777-16","price":68.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0669\/9971\/4099\/files\/be78541f0fa234a030316b6c0e3a90c1_594303c3-92a9-4daf-a652-a8ba5f516987.jpg?v=1761458602","url":"https:\/\/pureautoperformance.com\/products\/comp-cams-id-spring-seats-1-55-x-630-x","provider":"Pure Auto Performance","version":"1.0","type":"link"}
