EngValve Spring Seat

Additional Information

Constructed from hardened steel alloy, COMP's locator cup handles high RPM and extreme spring pressures while holding the spring. Our 4709 features a 1.455" OD with a .570" ID that works with our 26921, 26926, and 26925 dual valve springs.

Engine Valve Spring Seat

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.
