Why are these spring seats better than standard shims for high-performance engines?

Standard shims can deform or fail under the extreme spring pressures and high RPMs common in racing engines. These hardened steel alloy seats are built to withstand those conditions, protecting the head and shim while ensuring the spring stays properly located.

What is the advantage of the I.D. locator design?

The I.D. locator design has the locating shoulder on the inside, fitting around the spring. This often requires less machining on the cylinder head compared to older external-locating cup designs, simplifying installation.

What is included in a set of these spring seats?

Each set contains 100 individual spring seats. This quantity is typically enough for a complete V8 engine build, covering all valve springs.

Product Details

These COMP Cams ID Spring Seats are made from a hardened steel alloy, a solid choice for engines that see high RPMs and extreme spring pressures, like those in racing applications. Unlike older shims that can fail under stress, these seats are built to last. They not only shield your cylinder head and the shim itself from damage but also provide a stable platform to keep the valve spring precisely located. This is crucial for consistent valve train operation, especially when you're pushing the limits.

What sets these apart is their design. Instead of a cup that requires significant machining on the cylinder head, COMP Cams offers an inside diameter (I.D.) locator. This means the locating shoulder is on the inside, fitting snugly around the spring. This design simplifies installation compared to older external-locating cups, reducing the need for extensive head modification. You get a well-built part that ensures your valve springs stay put, contributing to reliable performance when you need it most.
