{"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":51374304330027,"sku":"CCA4708-16","price":135.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0951\/1868\/8555\/files\/3fc3de04dd32c0f71c4c84d48092f941_febb8e71-9fe5-4fcb-80d5-e3a91c3ab050.jpg?v=1760095416","url":"https:\/\/shop.adrenalineperformancellc.com\/products\/comp-cams-spring-seat-cups-1-690","provider":"My Store","version":"1.0","type":"link"}
