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\u003eConstructed from hardened steel alloy, COMP's locator cups handle high RPM and extreme spring pressures while holding the spring. Our 4702 features a 1.730\" OD with a .640\" ID that works with a number of our 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":51784016232760,"sku":"C007 4702-16","price":91.62,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/spring-seat-cup-060-640-i-d-1-730-o-d","provider":"MOTORMIA","version":"1.0","type":"link"}
