COMP Cams Spring Shims .030 X 1.437

COMP Cams is well-known for performance valvetrain components. These valve spring shims are a simple but important part of ensuring your engine runs right, especially if you're working on a performance build or rebuilding your top end. Their main job is to help you get all your valve springs installed at the exact same height. This consistency is key for proper valve sealing and overall engine performance.

These shims are made from heat-treated shim stock, which means they're built to handle the stress from aggressive camshaft lobes without deforming. With a 1.437-inch outer diameter and a .030-inch thickness, they're designed to fit precisely where you need them. Getting the installed height right on every spring helps prevent issues like valve float or inconsistent spring pressure, which can affect how your engine runs, especially at higher RPMs.
