COMP Cams ID Spring Seats 1.55 X 570 X

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. Made from hardened steel, these locators use an inboard locating shoulder to center the seat and hold the spring in place. The 4785 features a 1.550" OD and a .570" ID that works well with our 917, 919, and 943 dual valve springs.

The COMP Cams ID Spring Seats are engineered to withstand the extreme spring pressures and high RPMs prevalent in today’s race engines. Crafted from hardened steel alloy, these valve spring locators provide a durable and reliable seating solution that protects the cylinder head and shim while securing the spring in place. Unlike traditional cup-style locators that require extensive machining of the cylinder head, this design features an internal locating shoulder that simplifies installation and enhances performance. The inboard shoulder ensures precise centering of the seat, preventing spring movement and maintaining optimal engine operation.
Designed specifically for high-performance applications, the COMP Cams CCA4785-16 model features a 1.55-inch outer diameter and a 0.570-inch inner diameter, making it compatible with popular dual valve springs like the 917, 919, and 943 series. The thin, hardened steel construction ensures longevity and resistance to wear, even under the most demanding racing conditions. These valve spring seats are an essential upgrade for race engines where reliability and precise spring positioning are critical. Proper installation of these seats can lead to improved valve control, reduced valve float, and increased engine durability.
Whether you're rebuilding a high-performance engine or preparing for competitive racing, the COMP Cams ID Spring Seats provide a robust and efficient solution. Their design minimizes the need for extensive machining and ensures consistent spring positioning, contributing to overall engine stability.
