{"product_id":"comp-cams-spring-seat-cup-1-550","title":"COMP Cams Spring Seat Cup 1.550","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":52578534916403,"sku":"CCA4700-1","price":11.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0669\/9971\/4099\/files\/63e83236f00b3c7df297561291b8f1ff.jpg?v=1761458545","url":"https:\/\/pureautoperformance.com\/products\/comp-cams-spring-seat-cup-1-550","provider":"Pure Auto Performance","version":"1.0","type":"link"}
