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 4780 features a 1.540\" OD and a .640\" ID that works well with our 938, 953, 927 and 929 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":51783884767544,"sku":"C007 4780-16","price":91.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/horsepower-asset-426679-4767282-square_8df0192c-4d4b-4426-8a2d-b040d9bfc2a0.webp?v=1779469217","url":"https:\/\/store.motormia.co\/products\/spring-locator-1-540-o-d-640-i-d-060-thickness-2","provider":"MOTORMIA","version":"1.0","type":"link"}
