{"product_id":"comp-cams-spring-seats-cnc-100x-535x1","title":"COMP Cams Spring Seats Cnc .100X.535X1.","description":"The old standard shims will not hold up to the extreme spring pressures and high RPM in today's race engines. 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.","brand":"COMP Cams","offers":[{"title":"Default Title","offer_id":51534122058048,"sku":"CCA4713-16","price":104.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/5614\/5216\/files\/0bdf1246-ca68-4aa8-9714-c44401f5191b-800.jpg?v=1770992655","url":"https:\/\/velocityracewerks.com\/products\/comp-cams-spring-seats-cnc-100x-535x1","provider":"Velocity Race Werks","version":"1.0","type":"link"}
