What is the purpose of these spring seats?

These seats are designed to protect your cylinder head and shims from the extreme pressures of high-performance valve springs. They also help to precisely locate and hold the spring in place, ensuring consistent valve train operation.

How do these differ from older style shims?

Unlike older shims that might not hold up under extreme spring pressures and high RPMs, these are made from a hardened steel alloy. They also feature an internal I.D. locator, which means they don't require extensive cylinder head machining like some external cup designs.

What is included in this set?

This set includes 100 individual spring seats, providing enough components for a complete engine build. The dimensions are 1.565" OD, 0.535" ID, and 0.100" thick.

Product Details

These COMP Cams spring seats are made from a hardened steel alloy, measuring 0.100 inches thick with a 0.535-inch inside diameter and a 1.565-inch outside diameter. In today's high-RPM racing engines, standard shims often can't handle the extreme spring pressures. This is where these seats come in; they're designed to protect both the cylinder head and the shim itself, while also ensuring the valve spring stays precisely located and held in place.

Unlike older designs that required significant machining to fit an external cup, COMP Cams developed these with an internal I.D. locator. This means the locating shoulder is on the inside, working with the spring cup to keep everything stable. This design choice makes installation more straightforward, especially when building high-performance engines that demand reliability under stress. You get a solid, well-built component that addresses a common failure point in demanding applications.

This set includes 100 individual spring seats, giving you enough for a complete engine build. They are a practical solution for anyone looking to ensure their valve train components hold up under extreme conditions, offering a durable and effective way to manage spring pressure and location.
