Frequently Asked Questions

Will this fit my Softail?

Yes — fits all Milwaukee-Eight Softail models. Verify your engine is M8 before ordering.

Is this a single gasket or a set?

Single gasket per pack. Order multiples if you need spares.

How do I know if I need a new primary housing gasket?

Primary leaks at the cover seam, or gasket failure during routine maintenance, indicate replacement is needed.

Do I need any special tools to install?

Standard motorcycle hand tools and a gasket scraper are typically sufficient. Torque specs should follow your factory service manual.

Almost identical to OEM. Good fit. I did miss that they are sold as each and not as a pair. Small detail and my fault but it did slow my project down a bit.
