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":45481569976377,"sku":"02Z4R","price":11.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0762\/8632\/8889\/files\/63861c6ec926836965b14a148eb41f4a_d208d743-a971-40aa-983d-1e640a128b3e.jpg?v=1774076509","url":"https:\/\/shop.throttletherapynation.com\/products\/comp-cams-1-300-x-520-id-spring-seat-for-gm-ls1-1","provider":"Throttle Therapy Nation ","version":"1.0","type":"link"}
