COMP Cams 4712-1 - Spring Seat For GM LS1 1.400in

ID Spring Locator - 1.400" OD, .520" ID, .060" Thickness

Made from hardened steel, this locator uses an inboard locating shoulder to center the seat and hold the spring in place. The 4712 features a 1.400" OD and a .520" ID.

The old standard shims will not hold up to the extreme spring pressures and high RPM in today's race engines. COMP Cams offers a simple but effective solution to this problem. These Valve Spring Locators provide a thin, hardened Steel alloy seat that 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.
