{"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":43287799496769,"sku":"CCA4690-16","price":68.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0553\/2637\/6001\/files\/1fb124eb-7614-443e-b416-0219963e49e5-800_30d95b64-c96e-403a-854c-be8296290df7.jpg?v=1769489678","url":"https:\/\/shop.kingsperformance.com\/en-de\/products\/comp-cams-spring-seats-120-x-780-x-87","provider":"Kings Performance","version":"1.0","type":"link"}
