Frequently Asked Questions

Will this fit my Twin Cam 103 engine?

Yes — this gasket fits both Twin Cam 88 and Twin Cam 103 primary housings.

Is this an OEM gasket or an aftermarket replacement?

James Gaskets manufactures OEM-grade gaskets to factory specifications. This is a direct replacement for the original equipment gasket.

Do I need to replace the O-ring derby cover seal at the same time?

It's a best practice to replace the entire primary housing gasket assembly when servicing the primary. Many riders replace both together for a complete seal.

0.12 inches thick, sized to seal the Twin Cam primary housing without shimming or modification.
