{"product_id":"comp-cams-spring-seat-120-x-780-x-878","title":"COMP Cams Spring Seat.120 X .780 X .878","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":41058046967857,"sku":"CCA4690-1","price":11.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0601\/4038\/8401\/files\/1fb124eb-7614-443e-b416-0219963e49e5-800_16dff13e-ad96-40f6-8c07-ba7813fcb141.jpg?v=1782527381","url":"https:\/\/apexspeedzone.com\/products\/comp-cams-spring-seat-120-x-780-x-878","provider":"APEX PERFORMANCE PARTS","version":"1.0","type":"link"}
