{"product_id":"comp-cams-id-spring-seat-1-55-x-570-x-8","title":"COMP Cams ID Spring Seat 1.55 X 570 X 7","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":45886316183731,"sku":"CCA4778-1","price":45.12,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0635\/1831\/0579\/files\/1fb124eb-7614-443e-b416-0219963e49e5-800_1bb94d6c-c8f7-4fd9-90f4-280391ac228c.jpg?v=1787449697","url":"https:\/\/www.standardautopart.com\/products\/comp-cams-id-spring-seat-1-55-x-570-x-8","provider":"Standard Auto Part","version":"1.0","type":"link"}
