Common questions

Will this gasket fit my Milwaukee-Eight engine?

No, this gasket is specifically designed for Twin Cam engines. Milwaukee-Eight models require a different gasket part number due to their unique design.

Is this an OEM Harley-Davidson gasket or an aftermarket part?

James Gaskets manufactures this as an aftermarket replacement to OEM specifications. While not a genuine Harley-Davidson part, it meets the same stringent sealing standards.

Where is this gasket located on the engine?

This gasket seals the rocker box cover base on Twin Cam engines, sitting between the rocker box cover and the base assembly to prevent oil seepage.
