4640-1 COMP Cams Spring Seats

Made from hardened steel, this locator uses an inboard locating shoulder to center the seat and hold the spring in place. The 4640 seat's 1.600" OD works well with our 26055 Beehive spring..

The old standard shims will not hold up to the extreme spring pressures and high RPM found in racing engines being built today. COMP Cams offers a simple but effective solution to this problem and a thin, hardened Steel alloy seat which will not only protect the head and shim, but also locate and hold the spring in place. Previously, this part has been available only in a cup form with the retaining portion being on the outside of the part. This required that the head be machined a great deal to accept this cup so COMP now offers an ID locator with the locating shoulder on the inside, as well as the spring cup. Many sizes are available to locate from the inside or outside diameter.
