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 I.D. locator with the locating shoulder on the inside, as well as the spring cup.\u003c\/p\u003e","brand":"FR SPORT","offers":[{"title":"Default Title","offer_id":52711095075132,"sku":"047Z7","price":68.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0740\/5646\/6748\/files\/6dc6926ca4f45bfd249f61dc566f8e34_956ca5d3-9a12-4c87-8d79-4d07e97b852e.jpg?v=1770219857","url":"https:\/\/fortunehunterzmotorsports.com\/es\/products\/comp-cams-570-x-810-x-1-550-040-thick-id-seat","provider":"Fortune Hunterz Motorsports ","version":"1.0","type":"link"}
