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.\u003c\/p\u003e\u003cp\u003eMade from hardened steel, these locators use an inboard locating shoulder to center the seat and hold the spring in place. The 4778 features a 1.550\" OD and a .570\" ID that works well with our 938 and 927 dual valve springs.\u003c\/p\u003e\u003cp\u003eThis product may expose you to chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.\u003c\/p\u003e","brand":"COMP Cams","offers":[{"title":"Default Title","offer_id":51783875723576,"sku":"C007 4778-16","price":76.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/horsepower-asset-426841-4767318-square_ba76b5bc-2a27-4a9a-97f3-c25248016bb0.webp?v=1778288478","url":"https:\/\/store.motormia.co\/products\/spring-locator-1-550-o-d-570-i-d-060-thickness-3","provider":"MOTORMIA","version":"1.0","type":"link"}
