COMP Cams ID Spring Seats Eb 1.625 X 57 - Set of 100

If you're building a high-RPM racing engine, you know that standard shims can struggle under extreme spring pressures. COMP Cams offers a smart solution with these ID Spring Seats. They're designed to protect your cylinder head and the shim itself, while also keeping the valve spring properly located and seated. This updated design features an inside diameter (I.D.) locator with the locating shoulder on the inside, meaning you won't need extensive machining on your cylinder head like older cup-style seats required.

These seats are made from a hardened steel alloy, built to withstand the intense forces found in demanding engine builds. The 1.625-inch outer diameter and 0.570-inch inner diameter, combined with a 0.060-inch thickness, ensure a secure fit for many popular valve spring setups. Having 100 in a set means you'll have plenty on hand for multiple engines or for future projects.
