What is the main benefit of using these spring seat cups?

These cups are made from a hardened steel alloy to withstand extreme spring pressures and high RPMs. They protect the cylinder head and shim while also accurately locating the valve spring, preventing movement under stress.

Do I need to machine my cylinder heads to install these?

No, COMP Cams designed these with an I.D. locator shoulder on the inside. This means they locate from the inside diameter and don't require extensive machining to the head to fit properly.

What are the specific dimensions of these seat cups?

This set features a 1.475 inch outside diameter, a 0.640 inch inside diameter, and a thickness of 0.060 inches. They are designed to fit specific valve spring setups and provide solid support.

Product Details

These COMP Cams Spring Seat Cups are made from a hardened steel alloy, a smart choice for engines that see high RPMs and extreme spring pressures, like those found in racing applications. Standard shims alone can struggle to hold up under these demanding conditions. These cups offer a straightforward yet effective way to protect your cylinder head and the shim itself, while also ensuring the valve spring stays precisely located. COMP Cams has updated the design to include an I.D. locator with the locating shoulder on the inside, meaning you don't need extensive machining to the cylinder head to install them. This updated design works with the spring cup to keep everything in place, even under significant stress.

This set includes 100 seat cups, giving you plenty for a full engine build. The 1.475 inch outside diameter is designed to fit specific valve spring setups, and the .640 inch inside diameter helps center the spring. At .060 inches thick, they add minimal height while providing solid support. This well-built component is a practical addition for anyone rebuilding a performance engine where reliability under stress is key.
