Frequently Asked Questions

What does an exhaust spigot do?

The spigot is the mounting boss where the exhaust header bolts to the cylinder. This replacement restores a worn or damaged attachment point.

Is this a direct bolt-on replacement?

Yes — it replaces the worn spigot on classic Panhead engines without modification to the cylinder.

Will this fit other Harley engines?

This part is designed for Panhead motors. Twin Cam, Shovel, and Milwaukee-Eight engines use different spigot geometries.
