The 1.437 O.D. Spring Shims from COMP CAMS are precision components designed specifically for valve spring support in high-performance engine builds. These shims are essential for maintaining consistent spring pressure and preventing valve seat wear in demanding engine applications.
Manufactured to COMP CAMS' exacting tolerances, the 1.437 O.D. Spring Shim features a .645 I.D. bore and .015 thickness that allows for precise valve spring pre-load adjustment. The thin-wall design minimizes mass while maximizing structural integrity, which is critical for maintaining proper valve timing and reducing harmonics during operation.
Engine rebuilding professionals and competition tuners rely on COMP CAMS spring shims for OEM replacement and performance upgrades. Installation requires removal of the valve spring assembly, and these .015-thickness shims are stackable, allowing builders to achieve the desired spring height and pre-load effectively.
