What is the purpose of these spring seat cups?

These seat cups act as a hardened steel alloy interface between the valve spring and the cylinder head. They protect both components from damage caused by extreme spring pressures and high RPM operation, while also helping to properly locate the spring.

What size valve springs do these seat cups work with?

These specific seat cups have a 0.640-inch inner diameter, designed to work with a number of COMP Cams valve springs that match this dimension.

Are these seat cups suitable for all engines?

This set includes 16 seat cups, which is appropriate for most V8 engines. They are particularly beneficial for performance or race engines experiencing high spring pressures and high RPMs.

Product Details

If you're building a performance engine that's going to see high RPMs and serious spring pressure, standard shims might not cut it. COMP Cams offers these spring seat cups as a well-built solution to keep your valve springs seated and protected. They act as a hardened steel alloy seat that sits between the spring and the cylinder head, preventing damage to both the head and any shims you might be using.

These aren't just simple washers; they're designed to properly locate and hold the valve spring, which is crucial for consistent valve train operation at high speeds. The hardened steel alloy construction means they can handle the extreme forces involved without deforming. This particular set, the 4702-16, features a 1.730-inch outer diameter and a 0.640-inch inner diameter, designed to work with a variety of COMP Cams valve springs.

This set includes 16 seat cups, enough for a typical V8 engine. They offer a straightforward way to add durability and reliability to your engine's valvetrain when you're pushing the limits.
