COMP Cams ID Spring Seats Eb 1.550 X 63 - Set of 100

COMP Cams is well-known for making performance valvetrain components. If you're building a high-performance or racing engine, you know that standard shims can struggle to hold up under the extreme spring pressures and high RPMs these engines see. These ID Spring Seats from COMP Cams offer a smart solution to protect your cylinder head and shim, while also keeping the spring properly located.

Unlike older designs that required significant machining to fit, these seats feature an inside diameter (I.D.) locator. This means the locating shoulder is on the inside, making installation simpler. They are made from a thin, hardened steel alloy that's built to withstand high stress. This set includes 100 seats, giving you plenty for multiple engines or projects. The specific dimensions for this set are a 1.540" outside diameter, a .640" inside diameter, and they are .060" thick.
