About this part

Product Details

Manley Performance valve spring shims are a small but critical component for ensuring your engine's valve train operates correctly. These shims are designed to fit between the valve spring and the spring seat, allowing for precise adjustment of installed spring height. Getting this height just right is important for consistent valve spring pressure and proper engine operation, especially when you're rebuilding or modifying your engine's top end.

This particular shim measures 1.437 inches in diameter and is 0.060 inches thick. They are well-built to handle the pressures within the engine. Ensuring the correct installed height for your valve springs helps prevent issues like valve float at higher RPMs or excessive stress on the valve train components. This is a straightforward part that plays a key role in the overall health and performance of your engine.
