What is the main benefit of using these COMP Cams spring seats?

These seats are made from a hardened steel alloy to protect your cylinder head and shim from extreme spring pressures and high RPMs. They also help locate and hold the valve spring in place, ensuring consistent engine performance.

Do these spring seats require machining of the cylinder head?

Unlike older styles that required significant machining for an outer retaining cup, these COMP Cams seats feature an inside locator. This design minimizes the need for extensive cylinder head machining.

What are the specific dimensions of these spring seats?

Each spring seat measures 1.300 inches in outer diameter and .570 inches in inner diameter, with a thickness of .060 inches. This set includes 100 pieces.

Product Details

In this set, you get 100 spring seats from COMP Cams. These aren't your typical shims; they're made from a hardened steel alloy designed to handle the intense spring pressures and high RPMs found in today's racing engines. They work by protecting both the cylinder head and the shim underneath, while also making sure the valve spring stays exactly where it needs to be.

What makes these seats different is their design. Instead of a retaining portion on the outside that requires extensive machining of the cylinder head, COMP Cams offers an inside locator. This means the locating shoulder is on the inside, working with the spring cup to keep everything stable. This updated design makes them easier to install without needing to machine the head as much as older styles.

These seats are a solid option for anyone building a performance engine where valve spring control is critical. They are specifically sized with a 1.300-inch outer diameter and a .570-inch inner diameter, and are .060 inches thick, ensuring a precise fit for many popular valve spring setups.
