Frequently Asked Questions
What thickness is this gasket?
0.020 inch — the standard thickness for Twin Cam and Evo base applications.
Will this fit my 2011+ Milwaukee-Eight?
No — this gasket is for 1999-2010 Twin Cam and Evo engines only. M8 engines require a different part number.
Is this an OEM Harley gasket or an aftermarket replacement?
Cometic manufactures this to OEM specifications as a direct replacement. It meets or exceeds factory sealing performance.
Do I need a new gasket every rebuild?
Yes — gaskets compress under engine heat and pressure. Always use a fresh gasket when you break down the crankcase.

Good gasket, I like these because they are the same thickness as factory, and do not change the end play on the cam and breather

Decent gasket. Sticks out of the nosecone cover a bit at the top as it doesn't follow the nose cone shape precisely. Seals well.
