Product Details

When you're building a high-RPM racing engine, especially one that's going to see a lot of hard use, standard shims just won't cut it anymore. The extreme spring pressures and high RPMs can cause them to fail. COMP Cams has a straightforward fix for this: these ID spring seats. They're made from a hardened steel alloy that's built to handle the stress.

These aren't just simple shims; they're designed to do a few important jobs. First, they protect your cylinder head and the shim itself from the intense pressure of the valve spring. Second, they help to properly locate the spring, keeping it seated correctly even when the engine is really working. COMP Cams offers these with an inside diameter locator, meaning the locating shoulder is on the inside, which is a neat design that helps keep everything stable.

This set comes with 100 seats, which is usually enough for a full engine build. They have a 1.635-inch outside diameter and a 0.570-inch inside diameter, with a thickness of 0.060 inches. This specific design helps ensure the spring stays put, which is crucial for consistent valve train operation at high speeds.
