{"product_id":"comp-cams-spring-seat-cups-1-690","title":"COMP Cams Spring Seat Cups 1.690","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":47834110984501,"sku":"CCA4708-16","price":183.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/1671\/0709\/products\/0448e5c774ddd57304ea9b0678980b86_3b71f742-ae43-497c-891b-ee87477a76e6.jpg?v=1705013801","url":"https:\/\/c3-garage.net\/products\/comp-cams-spring-seat-cups-1-690","provider":"C3 Garage","version":"1.0","type":"link"}
