{"product_id":"comp-cams-spring-seats-for-gm-ls1-1-400","title":"COMP Cams Spring Seats For GM LS1 1.400","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":62149108105587,"sku":"CCA4712-16","price":96.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0897\/6289\/0099\/files\/b13cfc25b07a68f9e8e4b09d84eb1cb4_839ed7cf-35f8-490d-b8a4-f2b92e9f36ec.jpg?v=1759309271","url":"https:\/\/dspperformancemotorsports.com\/products\/comp-cams-spring-seats-for-gm-ls1-1-400","provider":"DSP PERFORMANCE MOTORSPORTS","version":"1.0","type":"link"}
