COMP Cams Part 4779-8 Valve Spring Locators and Seat Spacers for Chevrolet Big Block Engines

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. Avoid 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. See 4779-1 for a single seat spacer.

Designed by COMP Cams, the 4779-8 Valve Spring Locators and Seat Spacers are engineered to withstand the demanding conditions of high-performance racing engines. These hardened steel alloy seat locators provide a durable, thin surface that protects the head and shim from extreme spring pressures and high RPMs, ensuring reliable valve operation during intense engine performance. The innovative design features an internal locating shoulder, eliminating the need for extensive machining of the cylinder head, which was required with previous external cup-style locators. This internal shoulder ensures precise positioning of the spring and reduces the risk of slippage or misalignment during engine operation. The seat spacers are specifically designed to prevent stacking of multiple shims under the valve springs, which can cause inconsistent spring pressure and affect engine performance. With a 1.732-inch outer diameter, these spacers are suitable for 1.568-inch outer diameter springs, providing a secure fit and optimal spring height adjustment. These components are ideal for high-performance applications, particularly in race engines where valve spring stability and longevity are critical. The product is made from high-quality materials to withstand the rigors of racing conditions and is easy to install, making it a valuable addition to any engine rebuild or upgrade. Whether you're working on a Chevrolet Big Block or other high-performance engines, COMP Cams' innovative solutions help maximize engine durability and performance. Proper installation of these spring locators and spacers ensures your engine maintains precise valve timing and reliable operation under extreme conditions, contributing to improved horsepower and overall engine efficiency.
