COMP Cams 4700-16 – Spring Seat Cups 1.550

Valve Spring Locator – Outside – 0.060 in Thick – 1.670 in OD – 0.640 in ID – 1.565 in Spring OD – Steel – Set of 16

Constructed from hardened steel alloy, COMP’s locator cups handle high RPM and extreme spring pressures while holding the spring. Our 4700 features a 1.670″ 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 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.
