What does the .043 inch thickness mean for my engine?

The .043 inch thickness is the stock dimension for this gasket. Using a gasket of the correct stock thickness ensures that your engine's compression ratio remains unchanged from its original specification.

What is layered steel construction?

Layered steel construction involves multiple thin layers of steel pressed together. This design provides a strong and durable gasket that can withstand the high temperatures and pressures found in an engine's combustion chamber.

Does this gasket come with any hardware?

This product is for the head gasket only. You will need to source any necessary mounting hardware or additional sealing components separately.

About this part

Product Details

If you're rebuilding the top end of your 1999 and later Big Twin motorcycle, a good head gasket is crucial for sealing the combustion chamber. This gasket from S&S Cycle is designed to match the stock pattern, ensuring a straightforward installation when you're putting your engine back together.

This gasket is constructed from layered steel, a well-built material that holds up well under the heat and pressure of engine operation. It measures .043 inches thick, which is the stock dimension, meaning it won't alter your compression ratio when installed as a direct replacement. The 4-1/8 inch bore size is also specified to match the original equipment, making it a reliable choice for maintaining your engine's original specifications.
