What material are these spring seats made from?

These spring seats are constructed from a hardened steel alloy. This material is chosen for its ability to withstand the high spring pressures found in racing engines.

What is the main benefit of using these I.D. spring seats?

The primary benefit is their ability to protect your cylinder head and shim while also accurately locating and holding the valve spring in place. This helps prevent spring movement and potential damage at high RPMs.

How do these differ from older style spring seats?

Unlike older styles that located on the outside, these feature an inside diameter (I.D.) locator. This design often requires less machining in the cylinder head to install.

Product Details

When you're building a high-performance engine that's going to see serious RPMs, standard shims just won't cut it anymore. The extreme spring pressures in today's racing engines can cause them to fail. That's where these ID Spring Seats from COMP Cams come in. You get a set of 100 of these well-built seats, designed to be a simple yet effective solution for protecting your cylinder heads and keeping your valve springs properly located.

These aren't your typical shims. They're made from a hardened steel alloy, which means they can handle the intense forces involved. The unique design features an inside diameter (I.D.) locator with a shoulder on the inside, along with the spring cup itself. This design helps to keep the spring centered and stable, preventing it from shifting under load. Because they locate from the inside, they often require less machining in the cylinder head compared to older styles that located on the outside. This set includes 100 seats, each measuring 1.500 inches in outer diameter, 0.585 inches in inner diameter, and 0.060 inches thick.
