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, this locator uses an inboard locating shoulder to center the seat and hold the spring in place. The 4770 features a 1.500\" OD and a .585\" ID that works well with our 985, 978, 924 and 939 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":51783801602360,"sku":"C007 4770-1","price":28.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/horsepower-asset-424466-4777821-square_5c1fee00-643a-45f9-ab0d-9bee73b45b66.webp?v=1778288444","url":"https:\/\/store.motormia.co\/products\/comp-cams-id-spring-seat-1-50-x-585-x-69","provider":"MOTORMIA","version":"1.0","type":"link"}
