COMP Cams 4786-16 - ID Spring Seats 1.635 X 570 X

Valve Spring Locator - Inside - 0.060 in Thick - 1.635 in OD - 0.570 in ID - 0.870 in Spring ID - Steel - Set of 16

Made from hardened steel, these locators use a shoulder to center the seat and hold the spring in place. The 4786 has a 1.635" OD and .570" ID that works well with our 959 dual springs and our 947, 948, 26082 and 26028 triple 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 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.
