{"product_id":"comp-cams-id-sprg-seat-1-300-570-840","title":"Comp Cams ID SPRG Seat 1.300*570*840","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 I.D. locator with the locating shoulder on the inside, as well as the spring cup.","brand":"FR SPORT","offers":[{"title":"Default Title","offer_id":45480858714169,"sku":"0HUTF","price":68.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0762\/8632\/8889\/files\/e7dcf7490f802cc6879b618bceba14ad.jpg?v=1772884997","url":"https:\/\/shop.throttletherapynation.com\/products\/comp-cams-id-sprg-seat-1-300-570-840","provider":"Throttle Therapy Nation ","version":"1.0","type":"link"}
