What is the main benefit of using these ID Spring Seats?

These seats protect your cylinder head and shim from the high spring pressures found in racing engines. They also help keep the valve spring properly located, preventing movement.

How do these differ from older style spring shims or cups?

Unlike older shims that can't handle extreme pressures, these hardened steel alloy seats offer protection and location. The I.D. locator design also requires less machining than previous cup-style locators.

What are the dimensions of each spring seat?

Each spring seat has an outer diameter of 1.550 inches, an inner diameter of 0.570 inches, and a thickness of 0.060 inches.

Product Details

COMP Cams is well-known for making parts that help racers get the most out of their engines. If you're building a high-performance engine that will see serious RPMs, especially for racing, the standard shims you might be used to just won't cut it anymore. They can't handle the extreme spring pressures that modern racing engines demand. That's where these ID Spring Seats come in. They're a straightforward but really effective fix.

These seats are made from a thin, hardened steel alloy. They do a couple of important jobs: first, they protect both the cylinder head and the shim underneath from the intense pressure of the valve spring. Second, they help keep the spring properly located, preventing it from shifting around. COMP Cams used to offer a cup-style locator that required significant machining to fit into the head. Now, they offer this I.D. locator version, which has the locating shoulder on the inside, fitting directly into the spring cup. This set includes 100 seats, each measuring 1.550 inches in outer diameter and 0.570 inches in inner diameter, with a thickness of 0.060 inches.
