COMP Cams 4705-16 - Spring Seats, for 26918 with . 570" Guide

COMP Cams Valve Spring I.D. Locators for 26918-16 Springs 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 I.D. locator with the locating shoulder on the inside, as well as the spring cup. I.D. Locator for 26918-16 Springs; Spring Locator O.D. is 1.300"; Spring Locator I.D. is .570"; Hardened steel alloy seat;
