COMP Cams Spring I.D. Locators [Locator Thickness .060" | Locator I.D. .520" | Locator O.D. 1.300" | Spring I.D. .640"]

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 − 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 I D 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.
