Constructed from hardened steel alloy, COMP's locator cup handles high RPM and extreme spring pressures while holding the spring. Our 4704 features a 1.570" OD with a .640" ID that works with a number of our valve springs.
The old standard shims will not hold up to the extreme spring pressures and high RPM in today's race engines. COMP Cams(R) 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(R) now offers an I.D. locator with the locating shoulder on the inside, as well as the spring cup.
