When it comes to engine performance, every detail matters. One of the most critical yet often overlooked components is valve spring height. Even a slight variation can lead to inconsistent valve timing, reduced performance, and potential engine damage. That's where precision-engineered valve spring shims come into play.
Over time, valve springs can compress differently due to wear, temperature changes, or manufacturing tolerances. This creates uneven pressure across your engine's valves, causing some cylinders to perform better than others. The result? Reduced horsepower, poor fuel efficiency, and uneven engine operation.
These .060" thick valve spring shims solve this problem with surgical precision. With a 1.500" outside diameter and .645" inside diameter, they're designed specifically for most standard valve spring applications. Made from high-quality shim stock and heat-treated to withstand the most aggressive cam profiles, these shims maintain their shape and performance under extreme conditions.
What sets these shims apart is their construction quality. Unlike cheaper alternatives that can deform under pressure, these are manufactured to exacting standards. The heat treatment process ensures they won't crack or flatten when subjected to radical cam lobes and high spring pressures. This means consistent performance whether you're running on the street or the track.
This set of 100 shims gives you plenty of options for different applications:
These shims are designed for straightforward installation. Simply measure your valve spring height, determine the needed thickness, and install between the spring and retainer. The precise dimensions ensure they fit perfectly without modification, saving you time and frustration during engine assembly.
Whether you're a professional engine builder or an enthusiast working in your garage, having the right tools and components makes all the difference. These COMP Cams valve spring shims represent that precision engineering that separates good engines from great ones.
