{"product_id":"comp-cams-id-spring-seats-1-55-x-630-x-1","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":47051427250343,"sku":"CCA4780-16","price":96.53,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/8344\/1063\/files\/c183646f875c7ad376caea19d7974fc9_4d63906f-b936-4dd5-8c90-a17bef2da5a5.jpg?v=1758231542","url":"https:\/\/www.straightsiximports.com\/products\/comp-cams-id-spring-seats-1-55-x-630-x-1","provider":"Straight Six Imports","version":"1.0","type":"link"}
