Common questions
What is the thickness of this head gasket?
This gasket has a nominal thickness of 0.045 inches. It's important to confirm this thickness matches your engine's requirements for proper compression and valve clearance.
Why is a fire ring important in a head gasket?
The fire ring is a critical component that directly seals the combustion chamber, preventing hot combustion gases from escaping. It's designed to withstand extreme temperatures and pressures, contributing significantly to a reliable engine seal.
Is this a bolt-on replacement for my Harley Evolution engine?
Yes, James Gaskets manufactures these to OEM replacement specifications. However, always verify the part number and dimensions against your specific Evolution engine model and year before installation to ensure perfect compatibility.
