{"product_id":"bdqq-4779-1","title":"Competition Cams 4779-1 Seat Spacers Spring Components","description":"Avoid stacking .300\" of shims under the valve spring on your Big Block Chevrolet with our seat spacer. This spacer features a 1.732\" outer diameter for 1.568\" outer diameter springs.\u003chr\u003eThe old standard shims will not hold up to the extreme spring pressures and high RPM in today's race engines. COMP Cams(R) 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(R) now offers an I.D. locator with the locating shoulder on the inside, as well as the spring cup.\u003cul\u003e\n\u003cli\u003eMade From Super Clean Wire\u003c\/li\u003e\n\u003cli\u003eCNC Machined\u003c\/li\u003e\n\u003cli\u003ePre-Set For Initial Load Loss\u003c\/li\u003e\n\u003cli\u003e1 Year Limited Warranty\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Competition Cams","offers":[{"title":"Default Title","offer_id":40313294258315,"sku":"COM4779-1","price":18.65,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0554\/5495\/7707\/files\/4779-1_8171db84-26a1-4823-bb88-dbd731608af6.jpg?v=1727910823","url":"https:\/\/jbspowercentre.com\/products\/bdqq-4779-1","provider":"JBs Power Centre","version":"1.0","type":"link"}
