Valve Spring Locator - Inside - 0.060 in Thick - 1.550 in OD - 0.570 in ID - 0.810 in Spring ID - Steel - Set of 16

EngValve Spring Seat

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.

Additional Information

Made from hardened steel, these locators use an inboard locating shoulder to center the seat and hold the spring in place. The 4785 features a 1.550" OD and a .570" ID that works well with our 917, 919, and 943 dual valve springs.

Product Overview

The older style 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.

As with all other areas in the valvetrain, the area where the spring sits also takes a beating. The old standard shims and/or seats simply will not hold up to the extreme pressures and high rpm found in today's performance engines. COMP Cams valve spring locators solve this problem and eliminate failures.
