Manley Valve Spring Shim, SHIMS-1.480 X .060

This is a Manley Performance valve spring shim, specifically the 03236-50 part number. It's a small but important piece for anyone working on their engine's valve train. When you're rebuilding or modifying cylinder heads, getting the valve spring installed at the correct height is crucial for proper operation and longevity of your engine components.

These shims are made from well-built steel and measure 1.480 inches in diameter with a thickness of 0.060 inches. Using the right shim ensures your valve springs are seated at the manufacturer's specified height, which helps maintain consistent spring pressure across the entire operating range. This consistency is key to preventing valve float at higher RPMs and ensuring your valves seal correctly under all conditions. It's a simple part, but getting it right makes a notable difference in how your engine performs and how reliably it runs.
