COMP Cams ID Spring Seats Eb 1.55 X 630 - Set of 100

If you're building a high-RPM racing engine, standard shims might not hold up to the extreme spring pressures you're dealing with. COMP Cams has a straightforward fix with these ID Spring Seats. They're designed to protect your cylinder head and the shim underneath, while also keeping the spring properly located. This is a well-built solution for engines that see serious use.

Unlike older cup-style seats that required significant machining to fit, these feature an inside diameter (I.D.) locator. This means the locating shoulder is on the inside, making installation simpler. The hardened steel alloy construction ensures durability under demanding conditions, preventing the spring from shifting and potentially damaging the head or shim. This set includes 100 seats, giving you plenty for multiple builds or engines with a large number of valves.
