COMP Cams ID Spring Seats Eb 1.550 X 57 - Set of 100

When you're building a high-performance engine that's going to see serious RPMs, standard shims just won't cut it anymore. They can't handle the extreme spring pressures that racing engines demand. 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 but effective solution for locating and holding your valve springs securely.

These aren't your typical shims. They're made from a hardened steel alloy, which means they'll protect both your cylinder head and the shim itself from damage. The unique design features an I.D. locator with a shoulder on the inside, which helps keep the spring centered and stable. This design avoids the need for extensive machining that older cup-style locators required. With an outside diameter of 1.550 inches and an inside diameter of .570 inches, these seats are made to fit a variety of popular valve spring setups.
