James Gasket Cylinder Head Gaskets

James Gasket cylinder head gaskets are replacement head gaskets for motorcycle engines, especially Harley-Davidson applications. They seal the joint between the cylinder and the cylinder head. This keeps combustion pressure, coolant and oil where they belong. The line is offered in several head gasket thicknesses. Thickness affects the engine's static compression ratio, so riders can choose a gasket that suits a stock rebuild or a performance build.

Key Features:

• Made in the USA by James Gasket, a brand known for Harley-Davidson gaskets and gasket kits
• Replacement head gaskets for many engine families, including Evolution, Twin Cam, Shovelhead and Panhead
• Available in different gasket thicknesses so you can choose the compression you want
• Construction options include multi-layer steel, copper, graphite and PTFE (Teflon) composites, and Fire Ring and Armor-style designs
• Many versions include O-rings where the original design calls for them

Use a James Gasket head gasket to restore a dependable seal during a top-end rebuild or a compression change. Pick the child item that matches your engine's bore and the gasket thickness you want.
