Valve Spring Shims 1.270 OD/.570 ID/.015

Valve Spring Shims 1.270 OD/.570 ID/.015 from Dura-Bond are essential components for engine builders and mechanics. These precision shims are designed to sit between the valve spring and its seat, helping to maintain correct spring pressure and preload. They are particularly useful for those working on engine rebuilds or modifications.

With an outer diameter of 1.270 inches, an inner diameter of .570 inches, and a thickness of .015 inches, these shims are engineered for specific valve spring configurations. They help ensure that the valve train operates smoothly and efficiently, reducing the risk of wear on components like rocker arms and cam lobes.

These shims are ideal for small-block and big-block engine rebuilds, especially when upgrading camshaft profiles or addressing valve spring pressure issues. Proper shim selection is crucial for achieving optimal engine performance and longevity, making these shims a valuable addition to any performance mechanic's toolkit.
