What material are these spring seat cups made from?

These spring seat cups are made from a hardened steel alloy. This material is chosen for its ability to withstand the high spring pressures and stresses found in performance racing engines.

Why are these better than standard shims for racing engines?

Standard shims can fail under the extreme spring pressures and high RPMs common in racing engines. These hardened steel alloy seat cups are designed to protect the head and shim, and also to securely locate the spring, preventing issues caused by movement.

What does the 'Eb 1.550' designation mean?

The 'Eb 1.550' likely refers to the specific dimensions or application for this particular seat cup, such as the intended spring diameter or the type of locator. The manufacturer offers various sizes to fit different engine builds.

Product Details

COMP Cams is a well-known name in performance valvetrain components, and these Eb 1.550 spring seat cups are a testament to their focus on durability for high-demand builds. If you're assembling an engine that will see high RPMs or extreme spring pressures, especially in racing applications, standard shims might not hold up. These seat cups offer a smart solution to protect your cylinder head and the shim itself, while also ensuring the spring stays properly located.

Unlike older designs that required significant head machining, this version features an I.D. locator with an internal shoulder. This design helps keep the spring centered and secure, preventing issues that can arise from movement under stress. They are made from a hardened steel alloy, which is crucial for resisting deformation and wear when subjected to the forces found in performance engines. This set includes 100 pieces, making it suitable for building multiple engines or for shops that frequently work on performance applications.
