COMP Cams ID Spring Seats Eb 1.55 X 630 - Set of 100

COMP Cams is well-known for performance valvetrain components, and these ID Spring Seats are a prime example of their focus on solving specific engine-building challenges. If you're putting together a high-performance or racing engine that will see serious RPMs, standard shims just won't cut it. These seats are designed to handle the extreme spring pressures that would otherwise damage your cylinder head and the shim itself.

What makes these seats a smart choice is their construction from a hardened steel alloy. This material is tough enough to resist deformation under high spring loads. Unlike older designs that required extensive machining to fit, these feature an inside diameter (I.D.) locator. This means the locating shoulder is on the inside, helping to center the spring and keep it seated properly without needing to cut into your cylinder head. They also act as a spring cup, providing a stable platform for the spring.

This set includes 100 seats, giving you plenty for multiple engines or for keeping spares on hand. The specific dimensions are a 1.540-inch outside diameter, a .640-inch inside diameter, and they are .060 inches thick, making them a solid option for many popular performance builds.
