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":45481105686585,"sku":"0218V","price":11.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/shop.throttletherapynation.com\/products\/comp-cams-120-x-780-x-878-x-1-253-seat","provider":"Throttle Therapy Nation ","version":"1.0","type":"link"}
