{"product_id":"comp-cams-spring-seats-120-x-780-x-87","title":"COMP Cams Spring Seats.120 X .780 X .87","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":47051418009767,"sku":"CCA4690-16","price":69.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/8344\/1063\/files\/d88d26eeb6005c5c74d50a2ae3ff3fe5.jpg?v=1758231441","url":"https:\/\/www.straightsiximports.com\/en-us\/products\/comp-cams-spring-seats-120-x-780-x-87","provider":"Straight Six Imports","version":"1.0","type":"link"}
