COMP Cams Spring Shims Eb .015 X 1.480in

These COMP Cams valve spring shims are made from heat-treated shim stock, measuring .015 inches thick with a 1.480-inch outer diameter. This specific material and thickness are important for handling the demands of radical camshaft lobe profiles. When you're rebuilding an engine or installing a new camshaft, ensuring your valve springs are seated at the correct and equal installed height is crucial for consistent valve train operation and longevity. These shims are a straightforward way to achieve that uniformity across all your valve springs.

Using these shims helps equalize the installed height of your valve springs. This means each spring will have the same amount of preload, which is vital for preventing valve float and ensuring reliable performance, especially with aggressive camshafts. The heat-treated construction means they're built to withstand the high stresses and temperatures found in the engine's valve train, giving you confidence in their durability.
