What is the main purpose of these spring seats?

These spring seats protect your cylinder head and the shim from extreme spring pressures and high RPMs. They also help locate and hold the valve spring in place, ensuring stability.

What material are these spring seats made from?

They are made from a hardened steel alloy, which is designed to hold up to the extreme spring pressures and high RPMs found in racing engines.

Do these spring seats require machining of the cylinder head?

No, these ID spring seats feature an inside diameter locator, meaning the locating shoulder is on the inside. This design avoids the extensive machining required by older, outside-locating cup-style parts.

Product Details

When you're building a performance engine that's going to see high RPMs and serious spring pressure, standard shims just won't cut it. COMP Cams has a well-built solution with these ID Spring Seats. You get 100 spring seats in this set, each made from a hardened steel alloy designed to withstand the demands of racing engines.

These aren't your typical shims. They act as a seat to protect both the cylinder head and the shim itself, while also providing a crucial locating feature to keep the spring centered. COMP Cams designed these with an inside diameter (I.D.) locator, meaning the locating shoulder is on the inside, preventing the need for extensive machining on the cylinder head that older cup-style locators required. The spring cup is integrated right into the seat, making for a clean and effective installation.

With an outside diameter of 1.550 inches and an inside diameter of .570 inches, these seats are .060 inches thick. They're a solid option for anyone rebuilding a performance engine where valve spring stability is critical.
