{"product_id":"comp-cams-rotator-eliminators-cb-exh","title":"COMP Cams Rotator Eliminators CB Exh.","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.\nAvoid stacking .300\" of shims under the valve springs on your Big Block Chevrolet with our seat spacers. These spacers feature a 1.732\" outer diameter for 1.568\" outer diameter springs.\nSee 4779-1 for a single seat spacer.\n\u003cp\u003eThe COMP Cams CCA4779-8 Valve Spring Locator Set is engineered to withstand the extreme spring pressures and high RPM conditions typical in modern race engines. Crafted from hardened steel alloy, these thin seat locators protect the cylinder head and shim while securely positioning the valve spring. Unlike traditional cup-style locators requiring extensive machining, this innovative design features an internal locating shoulder, simplifying installation and ensuring reliable spring retention. This upgrade is essential for racing applications where durability and precision are critical, providing a robust solution to prevent spring movement and reduce the risk of failure. The set is designed to fit Big Block Chevrolet engines with outer spring diameters of 1.568 inches, and the seat spacers can be used to avoid stacking excessive shim thickness under the springs, ensuring optimal spring pressure and longevity. These components are ideal for high-performance engine builds demanding enhanced spring stability and alignment, contributing to improved engine reliability and performance.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eHardened steel alloy seat for durability and protection against high spring pressures\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eInternal locating shoulder simplifies installation and maintains spring position\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesigned specifically for high-RPM, race-ready engines\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatible with Big Block Chevrolet engines with 1.568-inch outer diameter springs\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePrevents excessive shim stacking, ensuring optimal spring pressure\u003c\/li\u003e\u003c\/ul\u003e","brand":"COMP Cams","offers":[{"title":"Default Title","offer_id":53519759475004,"sku":"cca4779-8","price":101.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1865\/9007\/files\/74a423dd21b67dec2fa6794a8505eb67.jpg?v=1784236250","url":"https:\/\/necycleshop.com\/products\/comp-cams-rotator-eliminators-cb-exh","provider":"NE Cycle Shop","version":"1.0","type":"link"}
