{"product_id":"comp-cams-id-spring-seat-gm-ls71-270in-x","title":"COMP Cams ID Spring Seat GM LS71.270in X","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":45886338203827,"sku":"CCA4862-1","price":45.12,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0635\/1831\/0579\/files\/08fc0a36-91db-4a40-8d8d-c28c3fab9aab-800.jpg?v=1787449758","url":"https:\/\/www.standardautopart.com\/fr\/products\/comp-cams-id-spring-seat-gm-ls71-270in-x","provider":"Standard Auto Part","version":"1.0","type":"link"}
